I've been trying to figure this out for years. Almost everyone I listen to can make fuzz sound truly remarkable, but when I try it, it's either so muddy it doesn't cut through in a live situation or it's a lifeless fizzle thats bright and really not the sound I'm looking for. And not to mention if you have a buffer in the signal chain. Absolute poop. And then try using it with your favoriute wah pedal, complete poop. I've tried using it everywhere in the chain to boot. First, before wahs, after wahs, before overdrives, and after overdrives. I try to blend it with an overdrive - it's so muddy sounding on the neck pick up and still too dark on the bridge, and if you have the fuzz after the overdrive, it's really bright and shrill sounding. I've tried just about everything. I've owned a Fulltone 69, Dunlop Fuzz Face, PE Experience, PE Yard Box, Fulltone Soulbender (twice), Analogman Sunface NKT-275, MJM London Fuzz (GE), BYOC germanium clone, BYOC Silicon Clone, NYC Big Muff RI, Frantone The Sweet, Frantone Peachfuzz, and an expandora (even though it's not really a fuzz, it had a fuzz setting.) I've tried the Fulltone 70, Fulltone Ultimate Octave, McFuzz, other various no namers, etc..... I've tried just about everything there is. Why can't I get the sound I'm looking for?! I like the tone of the NYC the best and the sustain of the MJM London. I'm really messed up... :NUTS And yes I do have a FOXROX Retro-Fit in my wah and it does work wonders.
