Lovepedal Karl (2-knob version)
The Karl is essentially a modified Tim Escobedo Tripple Fuzz, basing it's sound around an NPN/PNP transistor network known as a "non-selective frequency tripler." I modified the power section a little bit. The original has an unnecessary 47µ cap at 9v input before the 330Ω resistor which I eliminated. I also moved the anti-popping pull down resistor to before the Intensity pot (the original had it after) and it might not even be necessary at all. But better safe than sorry.
You can mark this one as verified. I built the pcb and I like it a lot. Great sounding fuzz. Once again thanks for the layout!
ReplyDeleteAny idea of how is designed the tone control in the new version? I'll try the BM tone stack.
ReplyDeleteAnswer to myself, maybe it help somebody :-)
DeleteI found out on the net that the tone pot in the new version is a simple treble roll off control.
BMP tone stack would be a better choice I guess.
Is 1N5819 a good substitute for BAT46?
ReplyDeleteNot really. But just about anything will work there. Socket and experiment with what you have
