I've had this Bassman for 3 years, and it was serviced right after I bought it by my tech, who does good work. I know these amps are valued for their distorted tone, and I played this one cranked whenever I could and I enjoyed the distorted tone. In fact, it seemed I never played it clean. I was chatting with a friend who mentioned his steel player uses a similar amp and it got me wondering about my own amp - could I get a crystal clean tone? Turns out I couldn't. Normal channel, volume at 3, I was getting unpleasant distortion, especially at lower frequencies (like my open E string). Almost like it was getting choked. I thought it might be the cab, so I opened it up. Wiring looked a bit sloppy, and one speaker was 16 ohms.... swapped them both and wired it up nicely. My low volume, low frequence distortion is still there. I'm wondering if anyone has any hunches on what it might be? Pictures attached. I'm wondering if I have EVER heard what this amp can actually do?
