I have a '72 Traynor YBA 1 Bass Master. I don't know a lick about amps, let alone tube amps, and I'm curious if something is wrong with the amp. It's old so things can happen over time. I just purchased it off Reverb. I can get the eq I want out of it but my other amp, an Ampeg B5R, has all 3 eq pots working with equally wide eq sweeps. Is this something an amp tech could fix? Does it need fixing? I appreciate any of you knowledgeable TB folks chiming in.
