In the words of BBE:
Imagine a killer fuzz tone like Jimi at his best, with that creamy fuzz driving his Marshall into incredible sustain. For many fans, that tone is their holy grail. Unfortunately, the quest to find it is more like “chasing the dragon” because there’s so much hype and misleading information out there. Windowpane cuts through that nonsense with experienced engineering for tone so authentic you’ll swear the grail has landed on your pedal board.
The all-analog Windowpane’s two sequentially-wired silicon transistors are properly biased at the factory and the tone is dialed in with a carefully selected treble roll-off on the second transistor, recalling the slightly mellowed top end of early germanium transistor fuzz pedals. But unlike those old classics, Windowpane fuzz pedals are remarkably consistent from one to the next, thanks to reliable, predictable silicon transistors and low-tolerance 1% metal-film resistors. Add in high-voltage poly caps on a rugged circuit board and Windowpane delivers the mind-altering fuzz tone you’re after, gig after gig. And when you don’t want to melt faces, a properly engineered true hardwire bypass means signal passes entirely around the circuit, from input jack to output jack without a hint of loading.
Stop chasing the dragon and pick up a Windowpane, the experienced fuzz.
