So the reverb is dead on my Roadster Combo but here's the kicker, when i turn up the reverb knobs on the back i get an increase in volume and gain almost like if you turned up the gain on a OD pedal but no reverb. Im thinking the reverb tank is dead and signal is getting passed through the reverb knob and that's why I'm hearing more of the weird volume and OD like gain increase. Ive tried 3 or 4 different tubes in the reverb slot so I'm positive its not a tube issue, the other thing is maybe i didnt put the little RCA connectors from the reverb tank in the right slot I'm looking at amp from the back which one goes first white or black? What do y'all think could be the problem or have any of you had a problem like this?
