I would start with an electrolytic cap about 100uf on the black and red wires with the neg stripe on the cap going to the black wire. if you have access to a battery powered practice amp, the results would give us usefull information. also, is there a battery in your guitar? if so, can you use a guitar with passive pickups instead?


My bass does have a battery. It can switch from a passive to active mode. Just to test it, I switch from one to the other. When in passive mode, it almost makes no sound at all. When I put it in active, the fuzz functions but not like it should. When I tweak the eq on my bass and turn everything up, it works fine....very odd. I checked and I think I may have nicked one of the wires with the soldering iron. Being new to soldering, I can see how I would have done this very easily as I have really no idea what I'm doing. :picard: So there is a little spot on the black wire that looks like I hit it. I covered that with electrical tape and still the same issue. Should I get a new wire?

Also can you explain what I'm doing with the electrical caps? I'm not sure I understand.

well the problem here is that the bass has a preamp in it that is negative ground. the pedal is positive ground. there are all sorts of weird things that can happen. in a perfect world, one is operating at +9v and 0 while the other operates at 0 and -9v. but the magic is where one battery (or power supply) overpowers the other one or if one of the circuits makes dirty power for the other. any dirty power here means oscillation coming right through the DC blocking cap and you can hear it. putting a 100uf electrolytic cap across the power rails in the fuzz pedal should bleed these oscillations back to ground before they enter the fuzz pedal. electrolytic caps only work one way so always put the negative stripe on the negative or black. no guarantee that it will solve the problem. another option is to use a special cable that you can make yourself or use a plastic jack on the input of the fuzz pedal with a dc blocking cap somewhere on the ground. it might just be easier and more complete to put the battery back in the pedal. totally up to you if you want to spend time mucking about to see what works.

Cascades, no? Spooky into Lucky? Localized spacetime deformation?

The Spooky Tooth is pretty time melting by itself. The spooky
and Lucky can run in series, yes. The lower gain sounds sounded better
to me when cascaded. Honking midrange semi cocked wah tones and
overall weirdness/coolness.

I've considered giving them a try but I feel they would annoy me on a board.

...Does look nice though. :thumb:
