Just bought a Twin for a great price. New output tubes. All other tubes are orignal. When I use the reverb it doesn't hardly make a difference. Something changes but doesn't add reverb. Everything else works except the reverb. Tubes possibly bad ? Other suggestions ? I believe V5 & V7 have to do with the reverb.

I suppose it's '65 Twin Reberb.

For the reverb stage consult:
http://support.fender.com/schematics/gu ... ematic.pdf

The V3 12AT7 is the driver and V4b is used to mix with the clean sound, check also the tank and the wires, another thing is the footswich, may be a broken jack ...

(Edit: consult other same thread for Retroverbial answer with more details)

This one is just Twin, not the twin reverb or the '65. I'm going to check the reverb tank first. Funny thing there's no reverb at all. It does change sligghtly but just a little more static or white noise as you turn up the reverb. i'm assuming the reverb should work with out the pedal too. I know the trem works only with the pedal.

End up being one of the spring ends broke clean off in the reverb tank. Guess you just never know. Thanks for the response
