I’ve been fighting this thing for about 2 weeks now! Here’s the build thread... https://www.tdpri.com/threads/seems-like-i’m-doing-this-backwards.1015555/ in the course of trying to track down why this thing has such an excessive amount of gain, I have been trying various tricks and while doing so, I tried putting a resistor in between the phase inverter grid and the final gain stage coupling cap. This knocked the gain down considerably, actually too much, so I figured I’d clip in a pot wired as a variable resistor to figure out what value I would need to accomplish the desired amount of gain. In doing so, I (accidentally) discovered that with the whole preamp (theoretically) disconnected from the phase inverter, I’m still passing guitar signal. This signal responds to everything upstream, including volume, tone and reverb controls. I put on my jewelers magnifiers and turned on the best lighting and I cannot find anywhere that signal could be getting through. Any pointers on where I should look?
