Sempre dal sito di Kitrae a proposito del G2:
BIG MUFF OVERDRIVE / G2 - Pete Cornish, famed effects rig builder, has built a range of rugged, high quality, custom variants of many classic effects, including the P-1 (Ram's Head based) and P-2 (Russian based) Big Muff variants used by David Gilmour. Pete was creating his customized takes on the Big Muff long before the electronics community had the internet available to pass ideas back and forth. The G-2 was his third take on the BMP circuit, created in the early 1990's for Lou Reed, then sold to the public as a stand alone pedal circa 2002.
This is one of the more unique sounding revisions to the Big Muff circuit, in that it does not sound like a Big Muff at all, but more of a low gain, smooth overdrive. It features some very unusual component values, and trades the Silicon diodes for Germanium. The pedal also included Pete's signature unity gain input/output buffer system for a very clean and balanced signal to your amp. Strip away the buffer components down to the sound circuit and you find the basic Big Muff pathway architecture, with the high pass tone section and part of the low pass removed, and a slightly modified recovery stage (all shown in red). Ge diodes do not compress and distort as much as Si, and they cut the signal level down in the clipping stages, meaning less volume. Pete's blend of component values compensate and take advanatge of that.
