The insulation type and thickness is the only thing that matters for the voltage, for current (amps) it is the thickness of the copper that matters. For best practice I would go with better then 24 AWG for any pedal with tubes in it, but 20AWG might be too hard to get in the hole on the PCB...

I am also interested in this question, the Nobelium was designed to be a DI pedal first and foremost so the idea is that it should convert the unbalanced 1/4" signal to a balanced XLR signal as cleanly as possible. I think that a separate pedal is best for some drive or distortion. Which output...

I think that reverb might get too muddy at very low frequencies (from what I have read), it will be interesting to see what you come up with.

Lately there has been some people wishing that the Space Heater would become available again at Sushi Box FX, the Space Heater is apparently just a Particle Accelerator without a tone stack. You still need a 100nF 630V capacitor between V1 output and the Gain pot, and I imagine the output will...

I use 0.5mm2 wire which is close to 20 AWG for all wiring and that is plenty big enough, 22 AWG is also good to use. 24 AWG is fine for powering 1 tube pedals and it should be ok for a 2 tube pedal since it is just a very short run. If you are building a pedal with 3 or 4 tubes I would be using...

The resistors can be standard 1/4w resistors, they are not really needed but they help to bring up the voltage across the un-used caps so when you switch them in there is less chance of a pop noise. They will charge the caps slowly so not much current goes through them so 1/4watt will be fine...

I couldn't help myself but to check the different values so here are the pics, C9 different values. I am also considering using a different mid pot on my next build, using a 20k would give you a small gain boost. I might try a B20k pot for Mid next time EDIT: The flat tone stack response is...

You could go a lot lower as well, on Marshall JCM800's the lead input would use a 0.68uF capacitor in a similar position. I think I ran 2 wires to a switch on mine so I could select different capacitors to give me more tones, I can't remember what values I used.

My limit on SMD is 1206 size, and normal SOIC-8 size for Op Amps. I did one PCB as a front panel for an amp and I placed tiny SMD LED's under the knobs so they would glow, that looked fairly nice but a bit fiddly to make. (SMD pinheader on the inside for connections) I think these days it would...

That small PCB is an adapter PCB so you can mount SMD components onto TH PCB's. It looks like there is a MMBFJ201 SMD transistor mounted on it, it also looks like the legs are standard SIP pins. Some people sell the PCB bare and others will sell them with a MMBFJ201 already mounted. Tayda has...

I think the problem is in the switch itself, but I have been wrong in the past. I would replace the switch but if I was you I would check it with a meter first before doing anything.

This is the signal path to the switch. Try placing a jumper between 1 and 2 on the switch when you have it in bypass mode. The signal has to come to terminal 1 and 6 of the Switch PCB or it would not work in normal mode.

The only thing I can think of is a bad contact in the stomp switch, because it works when the effect is on proves there is a signal going into and leaving the stomp switch. On bypass the contact should be closed on the top left terminal to the middle left terminal on the switch. (looking at the...

Think of them as 2 separate volume controls working in opposite directions, except one goes from 0-10 and the other from 10-0. The difference is that you don't transfer from one pot to the other until they are both at full volume, when one pot goes to full volume the other pot starts to decrease...

Are you familiar with the MN taper pots ? they are dual pots where both are at full output at 12 a'clock. One track starts at 0% and goes to 100% at 12 a'clock and stays at 100% from 12'clock to 5 a'clock. The other track starts at 100% and stays at 100% till 12 a'clock and then it drops to 0%...
