This is a very subjective question... I think personally I never liked the reverb on any tube amp that I have owned. I guess that might be why your asking this question. The horrible part about it is that I never tried other reverbs and just stuck with what was there on the amp. However, I do love reverbs on solid state amps much better but not in regard to playing in a band. I love the reverb effect of solid states when practicing in low key environment on my own(no drums or whole live band). I think if I was gonna slap some reverb on it then I would choose a Boss reverb pedal or a Lexicon reverb rack mount unit. All this is subjective but reverb in tubes is a hard thing to get just right.
