Welcome to All Music Inc's Musicdungeon.

​Right now, you are looking at an insanely cool and rare effects pedal.

This is the 1972 Big Muff Pi 'Triangle' V1 guitar fuzz effect pedal.

Featuring the mystical and highly sought after FS36999 silicon transistors.

The mysterious FS36999 has become legendary in Big Muff lore as the most desirable of all silicon transistors.

This is part of what makes this pedal extremely rare - that at least 2 out of the 4 transistors (that I can read) are coded FS36999.

The CTS pot codes date them to 1972, which was the last year the V1 was manufactured.

First released in 1969 as the version 1 Big Muff, now known as the "Triangle" nicknamed for its triangular knob layout.

Join the likes of Santana, Lennon, and Howe (just to name a few) who recorded with this legendary model.

Featuring a Volume knob with the on/off switch built directly into the pot, a Sustain knob, and a Tone knob.

The indicator lines on the knobs do not line up properly, leading us to believe that they are replacements. Though when I was researching these pedals, there seemed to be inconsistencies of what the original knobs looked like.

The wide variety in sounds is one reason the V1 Big Muffs are so collectible. You can have two different V1 circuit variants that sound the same through an amp, then you blend them together with an overdrive and you find one sounds very different than the other.

This pedal is in great overall condition, especially considering its age. Thoroughly tested and works as it should.

Typical marks/scratches from use, but nothing that effects the awesome performance many consider to believe the best fuzz pedal ever created.

Even the skid pad on the back is in good condition.

We just installed a new 9v battery.
