FYI, I replaced a Mesa D350 with my Traynor SB 500H.What's your recommendation between the D350 and the Traynor?
I have an older GK MB500 Fusion which is awesome, but I don't think it's going to last forever. I enjoy a slightly driven sound which I've been getting with a boost pedal and the tube preamp in the GK. But I'd happily put a pedal or two before the new amp.
The Mesa was great but the bass notes in the lower register were too boomy for me and the Traynor SB500 is more articulate and clean. The Mesa sounded "generic" to me.
If I was playing soft jazz or using a fancy 5 or 6 string jazz bass, I would have kept the Mesa as it’s more hi-fi but I now play almost exclusively hard rock and blues with a p bass with stainless steel rounds so I wanted a more rough and aggressive tone with bass notes that burp and the Traynor does it well.
