Anyone having any noise issues? I am, and I'm trying to figure out whether it's transistors or power conditioning or what.

No noise issues here. I was actually kinda surprised how quiet it was. Have you tried it on a battery? I think that'd reduce power supply issues as a source.

Thanks, Corksniffer!

Can anyone help with how to wire the pots and the 3 way toggle switch?

I thought that I read that a resistor is not necessary for the on/off led. Is that correct?

When you look at a pot as installed in the enclosure with the lugs facing towards you, the lugs are numbered 3, 2, 1 from left to right. Just match up those lugs to the right lug number on the PCB.

With the SPDT switch youll only have three lugs. The middle lug has to go to the middle pad for the switch but the other two lugs can be connected to either side because the switch is just choosing between one connection or the other. If you use a Center-Off SPDT youll have a middle position for the LEDs too and get three sounds.

There is an LED pulldown resistor on the board. All you need to do is connect the positive leg of the led to the PCB pad marked LED and then connect the negative leg to your 3pdt stomp.

Thanks, Corksniffer,

The toggle that I got has 6 lugs. It's a DPDT. Did I get the wrong one? I'm not sure how to wire this one up.

Youll notice that you have two rows of lugs on a DPDT. You can just use one of those rows of 3 contacts and youll be perfectly fine. You just wont need to use the extra set of switching contacts.

I've done it on both a PP2+ and a battery. Gotta check it out and see what's up here.

is the pedal noisy when the guitar volume is off?

[Sweet T]

Don't know--I'll have to check that out.

[Sweet T]

No, does not seem to be noisy when the volume is off. The hiss/noise is relative to the volume knob--something I discovered this weekend. The dirt knob can be all the way up, but it may/may not be any noisier. Could it be something with the electrolytics I used? How important is it to use the exact voltages called for in the schematic (ie, as long as they're over nine volts, should it matter)?

[jfromel]

I usually try to use electrolytics that are rated about double the max voltage for power rails (100uf/16v for a 9v rail). If there is no noise when the volume is turned down then there is something before the fuzz that is generating the noise and the fuzz is amplifying and distorting that signal further. This is pretty common if you are using single coils or if you have a cable that is old.

[Sweet T]

All the EL's are 16 or 25 v. I actually wonder if it could be the volume pot--I used one I already had, recycled from a failed project.
