there is nothing wrong with my bass, I got a MIM jazz with hot pickups, compared to an american bass by my teacher, and I love the sound of it through almost every other amp I've tried - and I got 2 other jazzes which also sound good through my Kustom so...
Thanks for the advise on the EQ thing

I'll have a bash and C if it makes it sound better... I still prefer the sound of my Kustom over almost everything I've tried though, so I think a Kustom rig or large combo would probably be a good alternative...they got more watts too!
I suppose it is all down to personal taste, and maybe the trace combo just isn't for me
I usually just have the EQ wih a kind of hump leaning more to the left and tailing off a lot near the high mid-treble.
If an amp has warmth it just gives it a nicer tone, I can't really explain it - it's like "Why do people prefer valves over trannies?" - to me it just sounds unexciting and sterile, I didn't know till just that trace did valve amps too, so I can't really comment on their valve sounds...
Just out of interest, tho here prefers a valve amp to a solid state?
