Circa 1973-1977 (Pots typically date as early as 1972 and as late as 1977)
E-H had progressed to using larger boxes for their pedals around 1973 and the Big Muff was given an upgrade to this box for Version 2, and a new art nouveau-ish typface. It has come to be known as the "Ram's Head" version, based on the most common nickname. Early V2 Big Muffs shipped with a rubber skid pad attached to the bottom panel, similar to the Triangle Muff skid pad, but this was later changed to four rubber feet around 1974 or 1975. The list price was originally $39.95, but it could found for $32 and under according to some original owners. Around 1974 the price went up to $49.95. There were numerous versions of the V2 circuit, each with a slightly different sound. It was produced until around 1977.
David Gilmour of Pink Floyd got into using the Ram's Head Big Muff in the late 1970's and recorded some of the most famous solos in Rock and Roll with it. Ernie Isley of the Isly Brothers used a Ram's Head Big Muff throughout much of the 1970's. One can be seen in the photo below. J Mascis of Dinosaur jr is another well known user.
GRAPHICS - I have noted three editions, loosely differentiated by graphics colors and face graphic. The most notable change for the Version 2 Big Muff was the addition of the strange little elfin like face, with ivy-like hair that was added to the lower right corner of the front panel. This face graphic has led to the common nickname, “Ram's Head” Big Muff, or Ram Head. I have also heard numerous other nicknames, such as lambs head, face, sheeps face, and medusa head Big Muff. The face does not look at all like ram or sheep to me, but Ram's Head seems to have become the most common nickname for this version, so that is the name I use. The face graphic was printed in a box shape and also in a round shape on some V2 models, as you can see in the photos below. This now iconic graphic was used in Electro-Harmonix advertising and packaging throughout the 1970s, and continues to be used to this day. A person on one gear forum noted that the face resembles Mike Matthews! A graphic designer created the design in the early 1970's, and when Mike Matthews saw it he decided to use it as the company logo graphic.
The plain font used on the Version 1 Big Muff was changed to the more stylish Arnold Böcklin typeface, created by by Schriftgiesserei Otto Weisert foundry. This font was also used on several other EHX pedals from this era. Sort of an art nouveau font, this typeface was created in 1904, named after the Swiss surrealist painter Arnold Böcklin, who died in 1901. It was a very popular in the 1960s and '70s, and is very much associated with the early Electro-Harmonix look.
First Edition - Early production used the square face logo. BIG MUFF and the pi symbol were usually printed in red, with everything else in black. The word ON was in the graphics, but no OFF for the first editions with red and black ink. The missing OFF was also common to other EHX pedals from this time, like the Black Finger. These alwasy had a rubber skid pad on the bottom, like
Second Edition, the "VIOLET" Ram's Head - Later production changed the square face logo to a circle face. Graphics were all one color: usually all blue or all purple (nicknamed the Violet Ram's head), but there was also a short run in all red, and one in all black. There was also a circle blue graphic with the bottom of the circle chopped off.
Third Edition - Around 1974-1975 the word OFF was added to the graphics, the colors transistioned back to the common red and black, and the face logo returned the the square box. Production with OFF in the graphics almost always had four rubber feet on the bottom rather than the skid pad, but I have seen exceptions.
I am calling the Violet Ram's head a "second edition", since it is so well known as a separate version, although nothing really changed other than the graphic and colors. The circuit was similar to the previous circuit variant. Some people have claimed the violet color version was actually the first edition but information I have collected (original owner buy dates, pot codes, pcb boards, component types, knob types) indicate these were actually the fourth circuit variant of the V2 production. The fifth circuit variant had blue ink on the case, both ON and OFF in the graphics, as well as a flat area at the bottom of the round face logo. I suspect these were some of the last Violet Big Muffs made, as they can be found with both skid pas and 4 rubber feet on the bottom.
CONTROLS / KNOBS- The on/off switch was moved to the back panel for this version and the only power option was the 9V battery. The foot switch is a Carling SPDT. The three control knobs were now in a line across the top. As on the V1, none of the three control knobs on the V2 start at zero in the same place. This is due to the potentiometers (pots) being mounted to the circuit board with the leads wrapping over the edges of the board - one over the left side, one over the top, and one over the right side. Technically the tone pot now had treble and bass in reverse of the V1 Big Muff, but since the pot was now mounted upside down on the pcb, the treble and bass orientation appears the same as the V1. Pots had plastic D shafts. The first V2 Big Muffs had tall, skinny "reactor tower" shaped silver knobs that Electro-Harmonix also used for the Marveltone and Lyle OEM versions of the Big Muff, the last V1 Big Muffs, and other E-H pedals. There were three version of the reactor tower knobs, pictured below. A variety of other knob types were used as E-H searched for a knob style that they could use for all pedals. Around 1975 E-H settled on the common Daka-Ware black Bakelite type, with d-shafts, ridged sides, and protruding pointer. Most of those were made by Davies Molding of Chicago. Some of the alternate knobs found on V2s were purchased for use on the OEM versions, and others were used by E-H when they were trying to find consistant knobs for production before settling on the black Davies Molding knobs. Many of the odd knobs are thought to be after market replacements, but they are usually original.
ENCLOSURE - Similar 2-piece sheet metal enclosure as the V1, but in a larger size. First prodcution had a ridged rubber skid pad glued to the bottom as on the V1, changing to four rubber feet areound 1974-75.
CIRCUIT BOARD, COMPONENTS and the VIOLET V2 - All circuit boards were marked with the number 3003 and a stylized “EH” symbol. As with the V1 Big Muff, circuit board component types and values for the V2 frequently changed during production. At first glance there appears to be very little consistency in component types and values from one V2 circuit to another, leading one to believe production was sloppy, with parts seemingly picked at random. In reality, they were anything but random. There were at least 20 different circuit variants, each following a set schematic, and each repeated in production by the thousands. I call these different schematics "variants". For an explanation as to why there were so many different schematics used, see the V1 entry here. Among these, several common variants of the circuit can be easily identified. One of the first was the "47" version, from around 1973, nicknamed for the .47µF, .047µF, and 470pF caps and 470k resistors used. The "73" Ram's Head variant followed that. Next was the "Violet" Ram's Head variant in 1973, probably the most common version of the V2 circuit. The "White Can" variant was the next most common, circa 1974, followed by the common white box cap variants, circa 1975-76. You can read more details about the workings of the circuit here. Schematics for many of the circuit variants are posted here.
Early V2 circuits used mostly ceramic and polymer film capacitors, but around 1974 polarized electrolytic caps were used along with ceramic and film caps. There is also a variant with all ceramic caps, circa 1974, and another circa 1975. Resistors were almost always carbon composition type, but smaller carbon film type began to be used on the later V2s in 1975/76. Often you will see the two types mixed. Diodes were silicon type, but most were unmarked (black band only), or gray/black/silver bands. A few were marked 125, and some 1975-76 Big Muffs had 1N925 diodes. Based on measurements, and the diodes used in later Big Muff versions, it is assumed the unmarked diodes were 1N914/1N4148 equivalents. Circuit board colors varied through the production, beginning with yellow, tan, then brown, white, dark brown-red, then back to yellow, and light brown.
TRANSISTORS - Some V2 Big Muffs were made with silicon NPN (negative ground) button top shaped (TO106 package) transistors marked with FS36999 like the previous V1 Big Muffs. The non stock number marking was likely used to confuse counterfeiters, although it is unlikely that E-H ordered the custom mark, but rather purchased them from a supplier already marked this way. Some early V2's have also been seen with NPN 2N5133 (TO106 package) transistors, which is likely what the FS36999 tranys really were (see the V1 section). Several other transistors were also used, including: PNP (positive ground) FS3700 button top shaped, NPN BC239 half cylinder shaped (TO92 package), PNP 2N5087 (TO92 package) and NPN 2N5088 (TO92 package) transistors.
POWER - Power is from a 9v battery only. You can also use a 9V battery snap adapter like the 1 Spot CBAT and connect to a standard power supply with a negative center barrel type jack, like the Boss PSA120T, 120S, or 1 Spot 9V AC Adapter. Note while most V2 Big Muffs are negative ground (NPN) circuits, some are positive ground (PNP). The power of a PNP circuit cannot be daisy chained with standard NPN pedals with a negative center plug. The common ground on NPN pedals is negative, so if you daisy chain power to a PNP positive ground pedal it will short out the power. See the TRANSISTORS entry above to find out if your pedal is PNP or NPN. If you intend to add a standard 9V power jack that works with standard negative tip power supplies, you can find out where to wire the + and - wires by looking at the wiring diagram for your version, or simply follow the red(+) and black (-) wires from the battery snap.
CLONES OR SIMILAR PEDALS - Note that since there were numerous versions of the real Big Muff V1 and V2 circuits there is no one version to clone, and some clones have modifications to the Muff circuit design. For those reasons most of these clones sound different from each other. Jordan Creator made by Jordan circa 1971, Mirano EF-1 Exiting Fuzz (Japan) circa 1971, Sekova Big Muff (Japan), Maccanbell Big Muff Sustainar (Japan), The Supa Tonebender made by Sola Sound of Britian circa 1973, Elk Super Fuzz Sustainer (Japan), Elk Big Muff Sustainer (Japan), Electro Sound Big Muff Sustainer (Japan), Big Mag Sustainer (Japan), Hohner MF-50 Tri-Dirty Booster from around 1976 (USA), Ibanez OD-850 Overdrive/Maxon OD-801(third version, Japan) circa 1979, Ibanez 60s Fuzz - SF-5 metal case/FZ-5 plastic case (Japan) circa 1990. Some modern clones or alternatives are the D.A.M. Ram's Head (UK), Ronsound Hairpie '75 (USA), BYOC Large Beaver (USA), Stomp Under Foot Ram's Head and Violet Ram's Head (USA), Top Tone Drivegate DG-1 (Brazil), Sweet Sound Pi Face (minus the tone control), Tym Guitars Big Mudd (Australia), Basic Audio Ram/Triangle Big Muff, Electronic Orange Pig Hoof (Czechoslovakia), Dice Works Muff Diver (USA), MJM Foxy Fuzz (USA), Skreddy ? Lady and Ernie (USA). The Skreddy Mayo, Mayonniase, Pink Flesh, Pig Mine, are all similar, but based around V1 component values. The Pete Cornish P-1 (UK) is one of the best Ram's Head replica's. See DiscoFreq's Effects Database for a thorough listing of all the Big Muff clones and variants throughout the years.
THE SOUND - It should be clearly stated that there is no 'one' Ram's Head Big Muff tone. Basically the V2 is just a new box for the V1. As with the V1 Big Muffs, the bass, treble, gain, and fuzziness of the tone varies slightly from unit to unit, sometimes wildy, due to constantly changing the schematic to work with component supply. I am describing some typical attributes here, based on dozens of examples I have played or own. The mids were very scooped, as in flat or removed, giving them a nice, dark sound. The tone is usually large and aggressive with a scooped grit, though some are more smooth sounding. On many later examples the sustain seems to be less than most V1 Triangle Big Muffs I have played. Some have slightly less clarity for leads, and can be difficult to palm mute through certain amps. The "violet" version would be an exception, as that one has a smooth clarity for leads and chords, and typically less bottom end. Some V2 Big Muffs will sound identical to some V1 Big Muffs. There is more of a mids scoop on most late model V2s that I have played versus the V1 Muffs, and a tighter bottom end. That bottom end creates a huge, thunderous sound through a tube amp. The scooped tone makes them easy to get lost in a band mix when playing live with certain amps. Listen to the Animals and The Wall era Pink Floyd albums for examples of solo tones using this pedal, and listen to Dinosaur Jr. for examples of the raw lead tone and wall-of-sound use of this pedal.

Shown above (left to right) - A 1973 Triangle V1 Big Muff with "reactor tower" knobs, one of the last produced in the small enclosure, and the larger first edition V2 Big Muff enclosure that replaced it. The larger pckaging retained the same graphics as the Triangle Big Muff. In the middle is a 1974 Electro-Harmonix magazine ad (click to enlarge) showing the new, larger V2 enclosure with the same knobs, all in line. These knobs were also used on several other Electro-Harmonix pedals, including the Black Finger sustainer. To the right is a warranty card packed with the V2, showing the 15 West 26th St address.
Shown above - Two V2 "Ram's Head" Big Muffs with the new enclosure, new Arnold Böcklin typeface, pots dated 1973, and the new "47" circuit, manufactured circa 1973. The "reactor tower" knobs shown are the first version, with the indicator dot on the front, identical to the knobs used on the last V1 Big Muffs (shown below) just prior to changing to the larger V2 enclosure. Knobs on bottom left are after market replacements. Many other production knobs were used, including the common black Daka ware knobs. This rare circuit is nicknamed the "47" version. It features unusual .47µF and .047µf input, clipping, and coupling caps (typically .1µF or 1µF), 470pF feedback filter caps, and 470k feedback resistors. The word ON is shown in the graphics but no OFF, typical for the early V2 Big Muffs. I have seen several examples with this exact circuit. Component types sometimes vary, but all have the yellow pcb's marke NVF, and same round green .47pF capacitors. The NPN ransistors were marked FS36999 327, or 2N5133 301. Those were likely the exact same transistor. (thanks to G Smith for the pix on top, and O Joseph for two circuit pix onbottom).
Shown above - A V2 Rams' Head Big Muff with the same "47" circtuit shown above. It was purchased new in 1973 or 1974. The battery clip has been replaced, but according to the original owner the Muff shipped new with these unique knobs from E-H (thanks to John C for the pix). On the right is another V2 with the same knobs, both missing the word OFF from the graphics. EH was still searching for the right knobs for their pedals, and in the process tried many different types.
Shown above - All V2 Big Muffs have the exact same circuit board, marked with the numbers 3003 and a stylized EH logo. They came in a variety of colors. Boards made in the first year of production have printed manufacturer markings like NVF and MC7. Many of these early V2's used the mysterious NPN FS36999 transistors (#FS36999 327), which were almost certainly Fairchild Semiconductor 2N5133 transistors (#2N5133 301) with a special mark. These mysterious transistors are considered the holy grail of the Big Muff universe, as current 2N5133 production are of lesser quality, noisier, and generally have a much lower HFE. Probably too much emphasis is placed on transistors, as the capacitor and resistor values are actually what sculpts the sound, but good transistors seem to have a richer tone.
Shown above - A V2 "Ram's Head" Big Muff with pots dated 1973, NPN FS36999 transistors, and production "reactor tower" shaped knobs. Commonly called the "73" Ram's Head. Note this version of the knobs does not have the indicator dot. This is likely the second circuit version for the V2. PCB board were yellow on the populated side with NVF markings, just like the "47" circuit boards shown above. The circuit includes carbon composition resistors, Silicon diodes, and Polyester film caps. Most Big Muffs from this time have fat polyester film caps like this, in black or the more common red-brown color shown below. The more common version of this circuit had .12µF caps rather than .1µF shown here. This is one of the best sounding Ram's Head Big Muffs I have ever played.
Shown above - A few more early V2 Rams' Head Big Muffs circa 1972-73 with "reactor tower" knobs, black Daka Ware knobs, and other prodcution knob types. Knobs on the right are likely after market knobs. The circuit is the same as the 1973 schematic shown above, but the .1µf caps are .12µf here. This same circuit was used in the Marveltone and Lyle OEM (original equipment manufacturer) versions made by Electro-Harmonix. Only the word ON is shown the graphics, but no OFF. The OFF was added to the graphics much later. All have rubber skid pads on the bottom. Note there were three versions of the reactor tower knobs used in prodcution.
Shown above (left to right) - "Reactor tower" shaped silver knobs used around 1972-74 on V1 and V2 Big Muffs. Also used on the Marveltone and Lyle OEM versions, as well as other E-H pedals like the Bad Stone, Frequency Analyzer, Black Finger, and the E-H made Guild Foxey Lady. The were three types, as shown above - indicator dot top, plain top, and indicator line top.

Shown above (left to right) - Several “Violet” V2 Ram's Head Big Muffs with the new circle face logo graphic. These were made with a wide variety of different production knobs and were printed with one of four different ink colors. These same knobs were are also used on many other E-H pedals from the mid 1970s. The word ON is in the graphics, but no OFF, and they always had a rubber skid pad on the bottom. The pots are almost always dated 1973 but the date on the example shown on the left with purple graphics is February 1975, making it hard to determine when these were actually made (thanks to Scott for the pix). In the middle are examples of each of the four ink colors ( purple, red, blue, and black) used by E-H, from the collection of J Mascis (photo by J Mascis).
Shown above - Another example of a "Violet" V2 showing the circuit. This was likely the fourth circuit version for the V2, and the most common version of the popular "Violet" schematic. These are considered among the best sounding and most desirable of the 1970's Big Muffs, and there were probably more of this circuit version made than any other. The rubber skid pad on bottom is a feature that dates this pedal to around 1973-1974. Knobs are actual production. The word ON is in the graphics, but no OFF. (Thanks to Steven C for the pix).
Shown above - More “Violet” V2 Ram's Head Big Muffs with the round face graphic, and the word ON in the graphics, but no OFF. Note the EHX Black Finger pedal with similar ink color, same fonts, and missing OFF. Silver knobs on the examples in the middle are actual production knobs. Circuit shown on the top right follows the popular "Violet" Ram's Head schematic. Most have 1973 pots dates.
Shown above - Common Daka-Ware knobs Electro-Harmonix used on V2 and V3 Big Muffs, and many other E-H pedals in the mid-late 1970s, manufactured by Davies Molding of Chicago. The three potentiometers were mounted in different orientations from each other, just like the V1 "triangle" Big Muffs.
Shown above - Bottom of an early V2 Ram's Head Big Muffs showing the large rubber skid pad, similar to the Triangle Big Muff skid pad. It was changed to four rubber feet around 1974-75, although the skid pad occasionally appeared on some later versions of the Big Muff in the late 1970s. Shown on the right is a V2 Big Muff schematic dated October 15th, 1975, possibly an actual E-H factory schematic. I have seen another version of schematic is on the web that is very compressed, but this one appears to be a photocopy of the original schematic (thanks to Bob for the scan)
Shown above (left to right) - Second version of the "Violet" Big Muff circuit, with 2N5133 transistors, circa 1973-1974. The circuit had a slightly different tone section and larger input and collector resistors, but sounded very similar to the first violet version. The graphics often fetaured the round face graphic clipped at the bottom. Early version had no OFF in the graphics a rubber skid pad on the bottom, and later version had both ON and OFF in the graphics and either a skid pad or four rubber feet on the bottom. The pots are almost always dated 1973.
Shown above - Various V2 Ram's Head Big Muffs with the "square" face and the word OFF added to the graphics. The silver knobs on the V2 shown on the left were actual production knobs that were also seen on V1 Big Muffs. The four Muffs on the right likely have after market replacement knobs. The one on the far right is mounted with knobs similar to the Dallas Arbiter Fuzz Face knobs from this period, similar to one David Gilmour has used on his touring pedal boards
Shown above - An Electro-Harmonox box stuffer, circa 1974, and a magazine ad for the V2 Big Muff, from December 1975. Note the price increased from $39.95 to $49.95.
Shown above - Several V2 Ram's Head Big Muff circuit boards, nicknamed the "White Can" Ram's Head. This is likely the fifth circuit version for the V2. These are easily identified by the large white axial poly film caps. Pots are almost always dated 1974, NPN FS36999 transistors, 680pF filter caps, and similar .1 or .12uF film caps.
Shown above - Another V2 Ram's Head Big Muff "680"circuit with pots dated 1974, NPN FS36999 transistors, and large axial poly film caps. Component types and values nearly match "680" circuits shown above (thanks to Steel Warrior for the pix)
Shown above - V2 Ram's Head Big Muffs showing the the “square” shaped face graphic including both ON and OFF in the graphics, and the now common Daka-Ware knobs. Original packaging and paperwork. Note the packaging graphics changed from the old Triangle Big Muff box art to the art from the V2 Big Muff enclosure silk screen.
Shown above - V2 Ram's Head circuit boards with pots dated 1975, NPN 2N5088 transistors, and box film caps
Shown above - Some V2 Big Muffs from around 1975-76 have NPN 2N5088 transistors with color bars on the back side
Shown above - A V2 Ram's Head with typical Daka-Ware knobs and both ON and OFF in the graphics. Pots are dated 1975 and the circuit was made with NPN BC239 transistors. The circuit is nearly identical to the one used for the B.Y.O.C. Large Beaver (Ram's Head spec clone), and is a rather common circuit. This is a typical sounding V2.
Shown above - Another common tV2 Ram's Head circuit board, with pots dated 1976. This one uses rare PNP 2N5087 transistors rather than NPN. Note the components types vary slightly from the NPN BC239 example shown above, as as is the case with almost all V2 Big Muffs, but the value selection had become relatively consistent at this time. True bypass and LED were added by Kevin Russel of KSR Custom Shop. This is a particularly good sounding late model V2. The B.Y.O.C. Large Beaver (Ram's Head spec clone) is identical to this version, only with NPN transistors. This is a typical sounding V2.
Shown above - Various V2 Ram's Head circuit boards from 1973 to 1976, all with exactly the same 3003 PCB trace pattern. Note that the component types and values vary from Muff to Muff, making each sound slightly unique. Also note the positioning of the potentiometers which caused the three knobs to each start with zero in a different position from each other, common to all V2 Big Muffs
THE LEGENDARY DAVID GILMOUR AND HIS PINK FLOYD BIG MUFFS (article updated 2011) - A V2 "Ram's Head" Big Muff was reportedly the most used Big Muff by David Gilmour, both in Pink Floyd, and in his solo recordings. It was famously used on the legendary Comfortably Numb solos, from Pink Floyd's The Wall double album, as well as many other Gilmour Big Muff guitar solos throughout his career. David's gear tech, Phil Taylor, said he introduced David to the Big Muff in 1974, though I do not believe David started using one regularly until around 1975 or '76. Big Muffs appeared on Pink Floyd's Animals/In The Flesh tour, David Gilmour's first solo record and tour, The Wall studio recordings, The Wall tour, The Final Cut studio recordings, likely many of Gilmour's guest solos on other artists songs from the 1980s/'90s, the Momentary Lapse of Reason studio recordings and 1987 leg of the tour, the Division Bell studio recordings, the On an Island studio recordings, and the 2006 On an Island tour. According to Phil Taylor, this #1 Big Muff he gave David "has often been preferred for most things" over all others David owned. The #1 unit was likely his main recording Muff, though David owned several different V1 and V2 Big Muffs for use in the studio and touring. Out of the many Ram's Head Big Muffs I have played, one of the few that really stood out among the others to me, and that sounded exceptionally Gilmourish, was one with similar component values to the Violet Big Muff circuit. It has the typical huge, dark V2 sound, but a clarity unlike many typical Ram's Heads, and not too thick and bassy. Perhaps David's is similar to this? Of course, there was a very large variety of different component values used for these early Big Muff circuits, and many different V2 sounds, so we will never know what David's truly sounded like.

THE LEGENDARY J MASCIS AND HIS DINOSAUR JR. BIG MUFFS - J Mascis is most well known as the frontman and lead guitarist for Dinosaur Jr, among his many other bands. J's sound on the early Dinosaur albums came from a Deluxe Big Muff, but he later transitioned to using vintage version 1 and version 2 Big Muffs, often using one particular favorite Ram's Head Big Muff. That pedal became the backbone of Dinosaur Jr's live sound. From his thunderous, punk rock power chords and complex rhythm playing, to his volcanic and melodic solos, J is a master of the Big Muff as a distortion pedal. J also owns an extensive collection of vintage USA Big Muffs from the 1970s. READ MORE
