I've got it on the breadboard right now, had to make a few substitutions - used a 100 ohm in place of the 10, 220nf instead of 180nf, 220uf instead of 100uf, 2k2 for 2k7 and a 4k7 for 3k9. Through a Jaguar (low output) it's really gated. Turning off the neck pickup barely cracks the gate at all. What's making it work this way? I'm guessing the 4k7 at Q4? Does anyone have working voltages their willing to share?


It sounds like the replacements you've made substituting R8 and R9 have thrown the bias points off. All the other subs you've made should be fine ;)

That's what I figured. I'll try to work up some parallel resistor combos with what I have to get as close as possible. Man, I wonder how they figure this stuff out. :scratch:

For some weird reason OSHpark turned off sharing for the PCB i designed. Here's a new one, in case someone wants to build one...
