David Gilmour’s Big Muffs
Few pedals are as Gilmourish as the legendary Big Muff. It’s been featured on some of David’s best performances including perhaps the greatest solo of all time – Comfortably Numb. In this feature we’ll look at the different models employed on the albums and tours.
The Big Muff was designed by Electro Harmonix founder Mike Matthews in the late 60s. The first years of production saw the pedal in various shapes and forms, both under the Electro Harmonix banner and other brands as well. As talked about in the Big Muff – Tone Tutorial feature, the early so-called Triangle and Ram’s Head (named by the alignment of the knobs) circuits was often hard to tell apart and few pedals sounded identical. You could very well end up with a Ram’s Head that sounded closer to a Triangle and vice versa. It seems that Electro Harmonix would use whatever parts they had available as long as they sounded somewhat similar. A nightmare for the avid collector but it’s perhaps this very inconsistency that made the Big Muff so special.
Phil Taylor (David’s backline technician since 1974), introduced David to the Big Muff in the mid 70s. Taylor had been hired during the summer rehearsals in 1974 and one of his main jobs (which continues to this day) was to upgrade David’s rig. They bought new Hiwatts, WEM cabs and lap steels and it was also around this time that David started to collect both pedals and rare guitars. Taylor explains: “I introduced David to the Electro Harmonix Big Muff Pi in 1974. He liked it, and he has continued to use one ever since. David has tried many of the different incarnations and models over the years, but his original has often been preferred for most things.“ – Phil Taylor, Guitar Player January 2009.
David might have gotten his first Big Muff in 1974 but it was not employed until the recording of Animals in 1976. Personally I think 1974 is a bit too early and a theory could be that he got the pedal(s) in 1975 during the US-leg of the Dark Side of the Moon tour or possibly later. In early 1976, David and Phil, comissioned a custom pedal board from Pete Cornish, that would feature both new items and some that had been in David’s setup since the late 60s. See this in depth guide to the Animals/Wall Pete Cornish pedal board.

Electro Harmonix “ram’s head” Big Muff
#1 “ram’s head” – David acquired the pedal sometime between 1974-76. The pedal has been featured on possibly every Floyd/Gilmour album since Animals but never used on a tour. Based on comments from Phil Taylor and Pete Cornish, it is likely that all of David’s Muffs, the ones featured in the Cornish boards and stand-alone pedals, has been modified to sound like this pedal.
#2 “ram’s head” – The pedal can be seen lying on top of David’s Pete Cornish 1976 pedal board during the 1977 Animals tour and later in the 1984 About Face and 1989-90 Momentary Lapse of Reason stage setups. The pedal was modified by Cornish to sound like #1 and it was also fitted with buffers and new round potentiometers – hence the Fuzz Face-like knobs. The pedal was last seen at the Bray Studios, London UK rehearsals in May 2006 but was never used for the tour.
The Pete Cornish 1976 Animals studio/stage board originally featured a Cornish P1. As noted above, the #2 Big Muff was lying ontop of the board paired with an Electric Mistress, throughout the tour. The board was modified after the tour, in October 1977, and according to Pete Cornish he replaced the P1 with a new “ram’s head” circuit (most likely modified to sound like #1) and he also built in an Electric Mistress cirquit, removing the two stand alone pedals (Guitar World 2006). The board was later used for David’s 1978 solo album and Wall 1980-81 tour. See this in depth feature about the Pete Cornish Animals board.
The Pete Cornish 1979 Wall studio board featured a “ram’s head” Big muff. The circuit was most likely modified to sound like David’s #1 “ram’s head”. The board was later used for the About Face and Division Bell recording sessions and possibly also The Final Cut sessions – David at least used a Big Muff on the sessions.
The Pete Cornish 1980 mini front stage Wall board features a “ram’s head” Big Muff. The circuit was most likely modified to sound like David’s #1 “ram’s head”.
The Pete Cornish 1999 All Tubes MkI board features a “ram’s head” Big Muff. The circuit was most likely modified to sound like David’s #1 “ram’s head” (it might have been required for the construction of the board or Cornish used a circuit from one of the earlier boards). The board was used for the 2001/02 semi-acoustic shows, On an Island studio sessions, Live 8 and on several guest appearances between 1999-2012. It was also used as a back up board on the 2006 On an Island tour.
Electro Harmonix “triangle” Big Muff
David probably own several so-called “triangle” Big Muffs but there are no reports on him using one during the Floyd days. However, one is seen on top of the Pete Cornish 2006 All Tubes MkII pedal board during the last leg of the On an Island tour, between May and August 2006. The pedal was connected via send/return looped with a T-Rex Replica echo – possibly used for Echoes where both pedals needed to be engaged simultaneously.
Pete Cornish P1
Originally called “Custom Fuzz” the P1 is loosely based on one of the many Big Muffs David presented to Cornish in late 1975 or early 1976. It was featured in the Animals session/stage board from January 1976 to October 1977 when it was replaced by a “ram’s head” circuit. It is not documented whether David actually used the P1 or perhaps the #1 “ram’s head” for the recording sessions – possibly both. It is also not known why David chose to have both the P1 and the #2 “ram’s head” (on top of the stage board) on the tour. He might have used both perhaps with different settings (one with high gain settings and one slight milder in a combo with the Colorsound Powerboost).
The Pete Cornish 2006 All Tubes MkII On an Island touring board features a P1 – most likely a new circuit.
Pete Cornish P2
Originally called “Precision Fuzz” the P2 was introduced around 1988 as an upgrade of the P1. The P2 is first seen in David’s 1989 Momentary Lapse of Reason stage rig after it replaced the #2 “ram’s head” Big Muff. It was also featured in the 1994 PULSE stage rig labeled “Big Muff”. Considering the small size of this early version it’s likely that it didn’t feature Cornish’s buffers.
Pete Cornish G2
The G2 isn’t really a Big Muff but one of Cornish’s more unique circuits – although it has obvious similarities to both the germanium Fuzz Face and early RAT models. The pedal was originally introduced around 1992 but wasn’t featured in David’s rig until the 1999 Pete Cornish All Tubes MkI pedal board. The board was used on the 2001/02 semi-acoustic shows, 2005 Live 8 and 2005/06 On an Island recording sessions as well as several guest appearances between 1999-2012. The G2 was also featured in David’s 2006 Pete Cornish All Tubes MkII On an Island touring board and used for many of the performed songs.
Sovtek “Civil War” Big Muff Pi
David is seen using this early Sovtek model during the 1993 Division Bell recording sessions. It’s not documented whether it was actually used for the album or not or if he perhaps employed one of the “ram’s head” models – or both. The pedal was again featured in the 1994 stage rig as David’s main distortion pedal for the tour.
David’s Big Muff tone
David’s Big Muff tone has changed a lot over the years since he first used during the recording of Animals in 1976. Different amp setups, pickups and recording techniques are employed to get the tones needed for the specific song or album as a whole.
The guitars were recorded with a wide range of microphones but the main source would often be a Shure SM57 placed slightly off center and 8-20 inches away from the cabinet. The slightest variation could create a whole different tone. Recording a Big Muff can be tricky and setting the amp up for that powerful, warm tube tone is essential to avoid harsh overtones.
Animals, David’s first solo album, The Wall and Final Cut were all recorded with a setup consisting of a 100w Hiwatt head with a WEM 4×12 speaker cabinet and a Yamaha RA200 rotating speaker cabinet. The signal from David’s pedal board or stand alone pedals would be split into these two amps and the Yamaha would often be mixed slightly lower for a mild, chorusy effect. This would also be David’s stage setup for the era. Animals is interesting because on most of the lead parts the Yamaha is almost left completely out of the mix. However, for some solos, like the ones in the verse sections on Dogs, the Yamahas are mixed quite high – almost leaving out the dry signal from the Hiwatts.

Most of The Wall would also be mixed this way – either dry or with the Yamahas mixed high in the mix. A crucial element to The Wall is also all the studio trickery that’s added in the mix and mastering. David’s guitars are often very compressed and gated, creating an impressive presence and punch. These tones would be almost impossible to recreate on stage.
David’s first solo album and Final Cut are perhaps the most honest recordings. It sounds like the mics have been placed further away from the speakers allowing a natural ambience for the Hiwatt and Yamaha. This perfect blend of the two adds a warm, liquidy flavour to the Big Muff, rolling off any harsh overtones and bringing out all the subtle nuances in David’s playing. On an Island is recorded in very much the same way although this time, David would use a much simpler setup with just the Big Muff plugged straight into the amp.
On tour, David often uses the Big Muff in combination with a booster/overdrive. This is not so much for boosting the volume but more like using an EQ. Although David’s preferred boosters, Colorsound Powerboost and Tube Driver, are very transparent, they have more character and balls than an EQ. The Muff is set fairly mild and the booster is set up for a slight volume boost at the very edge of breakup. The result is a much smoother Big Muff tone with a natural, dynamic attack and compression. This combo with the powerful Hiwatts is the essence of David’s live tones between 1977 to present.
Using a booster while recording is not a good idea because it’s often hard to tame both the increased gain and the noise caused by blending two gain effects. To get that same smooth, compressed Big Muff tone, David would play incredibly loud to get the amp’s tubes really hot. This was something he also would do to smooth out the even harsher fuzz pedals in the early 70s during the recording of Meddle and Dark Side of the Moon. As described above, mic placement and additional compression, limiting and EQ is also crucial to manipulate the tone.
