Hey folks! I bought a Fender Reverb Unit (90's Reissue) on eBay. The seller said he couldn't get a reverb signal to pass through so I asked for a small refund and to send the unit as-is. I got it today and have been playing around with it to try and get to the bottom of the issue. The Problem: The unit passes dry guitar signal only. I can give the unit a smack and will hear "the splash" but that's it. What I've tried: DeOxit on the pots and contact cleaner on the RCA jacks, Tube pins/sockets, and all mono jacks. Different 1/4'' cables Different tubes Different RCA cables Different Reverb tank Testing the Unit's cables and tank in a different amp (worked fine) The only thing that I can possibly think of would be that the electrolytic caps are outside of their useful life as this is an early 90s reissue... What do you think?
