I have an older Traynor YCV40. 40w, 2 x 5881 output valves, Celestion 70/80. It has it's shortcomings - the speaker can't handle low notes from a tele (why put such bad speakers in?) - and although it's quite a clear sounding amp, it doesn't really have a lot of midrange personality, if you know what I mean. I'm wondering if a speaker change can improve things or whether I should take the hit, sell it on for what I can get and find something else....any thoughts? I'm reluctant to get into a lot of speaker-swapping, as cash is tight. Just wondering about other folks' experiences. Any and all advice welcome.
