Not sure if I should have posted this in the tech area, but since the pedal is nearly 30 years old, I thought I’d start here.

I finally (!) got my Pedaltrain set up last night with everything mounted. Been playing around with different combos (not many) to see what worked and didn’t, but I’d left the Soul Preacher out figuring it would work pretty much anywhere. I don’t think the issue is with the compatibility with other components, but then I’ve never had trouble with it before (also hasn’t been used that much, sat for a dozen years in storage, and to boot, this is the first time I’ve run it off a power adapter).

It’s simply cutting out altogether, no signal. Generally when switched on, though a few times I lost signal with it off. Once I turned the threshold knob back a bit and the signal came through. Several time bumping the foot switch did the trick, sometimes without even actually switching it.

Another symptom I saw (first actually) was that switching one of a few different effects on or off would momentarily cut the signal (these were all after the Soul Preacher in the chain). I tried unplugging the effects that were in front of it and going straight into it. No change, still comes and goes (mostly gone at this point, generally I have signal with it off, and mostly not with it on).

One thing I’ve not tried yet is to pull the power cord and go back on battery (will try later or tomorrow), But I think something is probably loose or dieing inside the old Dude.

FWIW, signal path currently is: Tuner, Fuzz Face, Cry Baby Wah, vintage TS9 Tube Screamer, TS-808 Reissue Tube Screamer, Soul Preacher, Octavio (the Hendrix “cheese” pedal), Uni-Vibe, Phase 90 reissue, Carbon Copy and Micro Amp. Running a Stratocaster into a Fender Blues Deluxe.

Do we have someone, a “Guru”, Wizard of these vintage pedals to work on them? Does E-H still service a pedal this old? Any thoughts on what might be ailing it or what to try would be welcomed. TIA!
