im makeing one... can i use only the potentiometer and bypass the photocell completely ?

[thedefog]

Yep. I used a DPDT selector switch to go between the two, but you can omit it and just supply a pot.

Another thing you could do would be to add a range selector by putting in a switch with a cap that goes in and out of the circuit. Just make sure your math is right in conjunction with your pot value and resistor values so that the range is correct, unless of course you don't care about playing it musically and just want a noise maker.

Can you give me a link for the waveshaper? I can't find it anywhere and it's the only thing that I miss

@ignoranzanoisecore

You should just wire in a .047 cap with a pot to gnd like a guitar tone roll off. It sounds almost identical to the wave shaper I used in mine and is about 100 times less complicated.

shabby.

just inspired me to do some research and experiment.

i like your set up by the way.

fck organization. ha

[thedefog]

It has since been re-organized... But tends to get messy fast. Too much stuff.

Yeah it sounds like the weird wah stuff Mike does with the turntables.
