in dirty sock’s words:
based on the infamous "life" circuit, the black one v1.5 takes this concept further, with a completely redesigned circuit, for a greater breadth of tonal variety and lower noise. it's keeping with the original concept of an all-in-one distortion/fuzz box that includes a boost that will destroy the clean headroom of even the most stubborn amplifier.
the improvements start with a completely overhauled analog octave-up section. this octave is spittier and fuzzier than the original and pairs perfectly with the rat-style distortion placed after it. it uses hand-matched nos germanium diodes paired with modern silicon transistors. the "octave" control blends in the octave as you turn it up and can take you from mild octave-up tones to total end of the world octave-up fuzz.
the distortion segment (mass) stays true to the original 80's white logo circuit with some modern updates, including improved buffer circuitry and the addition of a clipping selector. the clipping switch allows for stock (symmetrical) clipping, op-amp clipping (loud!) and asymmetrical clipping. different settings change the distortion characteristic of the whole circuit, so choose wisely!
rounding out the circuit is a foot-switchable jfet booster stage that will deliver more than enough gain to push any amp into natural distortion. use it to push the front end of your amp or as a subtle clean boost for a little extra level – the choice is yours.
