You've done it again Anders, this is another MONSTER fuzz!
I've not got any 1k pots, so had to use a 5k. I'm sure a 1k will improve the sweep. I've only tried it with 2N2222 so far, so I will try others tomorrow, as it's too late to do it now.
I've had a play around with transistors - I don't have any of the originals. I've tried 2N2222, 2N2904, 2N5088, ME4003, BC108 and MP38.
My favourites are ME4003 and 2N2222 - ME4003 sounds darker, tighter and more compressed, and 2N2222 metal cans are brighter, with more fizz and a looser, more ragged fuzz. For me the 2N2222 wins out.
I'll have to get some 1k pots, as the sweep is lousy with a 5k. I'm sure this will get boxed up though, so thanks again Anders.
Yes, 2N2222's is the winner for me as well, tried 2N3409, 2N5088, Mp38 and BC108 and the 2222's suited me best. I really like the Eq control, it goes from really dark and heavy to a skanky blown out fuzz bliss.
Any chance you could add a gain control, per Brad/CreepyFingers' post here? I'm guessing the layout would need to be re-drawn a bit to accommodate the pot and adding the 240r limiting resistor.
Yeah I tried the distortion pot and it works really good but you want a log taper 50k pot for a good sweep.
Also I found out I preferred higher gain trannies like 2N5088, BC549C etc in there.
I built Ander's updated layout w/ gain and tried 2222's at first, but settled on 2n5089's. The original 2n3565 transistors varied widely in gains. I've read anywhere from 150-600 hFE, so I felt free to experiment.
It's a huge, heavy sound! I'm glad the gain control was figured out, as I usually have it backed off a bit to bring some pick attack in, while still being very distorted.
Just built one with bc109c's, really like it. Tone Machines blog described it as a cross between a Fuzz Face and an fy2, I think that's close. Gonna try some higher gain trannies and see what's what. Thanks for this one!
I built it today : it works fine, and has plenty of gain indeed !
The filter sounds a bit like a notch (not the regular tilt or low pass filter).
I tried with 2n222, and found it sounded much better than with 2N5088.
