ok, i built another fuzz, tried bc109's but they are just way too hot. bc108's tho, offer a pleasing tone, as do ac176 ge's. tested it with low gain transistors, you can get useable tone with anywhere from 30-120 hfe. i like the classic fuzzface-ish ratio, 87hfe q1 and 105hfe q2. this is verified, built it tonite, it has the potential to be TOO distorted. it's pretty sick, you can overload q2 if you want and make it fade in and out. not that you'd wanna do that. overdrive your amp, add fuzz, or both. have fun!
it's another 10,000 monkeys kinda thing, i'm sure it's been done before. if so, please let me know!!
got a prominent 2nd harmonic, cleans up nice from the guitar, seems to respect your guitar's tone when changing pickups.
nice sustain, too, not too gated. crank the overdrive control over about half, and it starts to get fuzzy. pegged, it can be REAL fuzzy.
criticisms also welcomed. just having fun. peace!
