My Hot Rod Deville 2×12 amp started acting up on stage, so I took it to Dennis. He fixed the problems, installed his magic mod and it now works perfectly. It sounds better than ever. The clean channel sounds like a good Twin Reverb, the distortion channel with guitar turned back sounds like a good Marshall and with the guitar turned up on full, it sounds like a good Boogie…it’s all here in one amp. I couldn’t be happier. Great service and killer results.
