Title: Man, this Total Recall just keeps having glitches
Post by: ckim715 on September 27, 2019, 08:33:08 AM
Got the bias issue solved, got the regulator issue solved, now it's a really really weird thing:

Even when the pedal is not powered, it passes signal when engaged. It is very faint, but it's there. I have it wired true bypass. I am assuming I have a short somewhere on my switch, but wanted to see what you guys thought. More digging to follow...

Sounds like a job for a continuity tester, probably just a loose strand of wire.

Continuity test shows that there isn't a short on the switch...anywhere else it could be?

Hm. Wondering if this is normal function. Does anyone else have signal pass through their true bypass wired Total Recall when there is NO power, but pedal is engaged?

It's not uncommon to have some signal through a circuit when it is unpowered. Look at the schematic - with no power there is an AC path from input to output through a series of resistors.
