CryBaby GCB95 True Bypass With DPDT Switch
« on: May 17, 2018, 07:51:47 AM »
Guys, have a problem with truebypass mod. My GCB95's original switch (3 leg spdt) broken some how... It wasn't go bypass and wah effect was staying always on. I have to say this; wah function was still working. So I wanted to change switch (6 leg dpdt) and a truebypass mod. I followed these steps;

Canceled the connection between input and buffer like this; http://media.stinkfoot.se/2010/11/pcb1.jpg
Made a new circuit like this http://media.stinkfoot.se/2010/11/pcb2.jpg
Finally wired like this http://imgim.com/d49055d9-8d1d-4f7c-afbc-4ab48ecaa526.png

So, i failed somewhere :) Pedal can go bypass now, but when i switch on, there is no signal. Only a very weak signal when i %100 push down.

Please help, best regards

I can't get what you drawn, I'm sorry.
But try to follow this layout:


Because you have a DPDT switch I guess it's enough to ignore the third column of lugs of the 3PDT footswitch (9v negative, resistor + LED).
