Uberdrive with DPDT diode options

[MatNasty]

Hi,

I'm building a Uberdrive and I want to add a 2 position DPDT switch with options for symmetrical and asymmetrical clipping. At the moment I tried to solder the wires where D2 goes. Is that correct? I plugged the pedal and nothing is working at the moment.

Thank you very much for any help!

Can you post pictures of both sides of the board?

D1, D2, and D3 are connected and set up for asymmetrical clipping already on the board. How do you have the diodes soldered on the DPDT? Or are you using a mod board like this?

Hi, thanks for your reply. Here are the picture where I soldered the wires.

Hi, I used a DPDT switch and soldered up position for stock asymmetrical and bottom for symmetrical. They are soldered to the switch.

I took this diagram. They are soldered exactly like that. Thanks!!

You could simply add a SPDT to short one of the diodes on the asymmetrical side. Anyways, I doubt the switch is the reason why the pedal doesn’t work. More pics may be needed for debugging.

Ok thanks, I might try that. I'll take pictures of the whole thing in the morning. Looking at the schematic and the direction of the diodes, doesn't it go through diode D3, D1 and then D2. I was wondering if I soldered the wires at the correct spot.

Thanks again for your help!

Yah the diode pads on the board are all connected, it wouldn't matter which set you soldered it to. If nothing is working at all (E.g, you're not getting pass through signal at all) then something else is going on. Even if you left the diodes completely out of the circuit you should be getting signal and op-amp clipping.

Thank you very much!! I'll check out everything in the morning and see if I did something wrong. I'll let you know!
