Thanks some good food for thought there. I play a Rickenbacker 4003 and a Fender P. I have used a Zoom bass pedal for a bit of distortion. I just feel that if I need a bit more head room there isn't anywhere to go!! I understand the use of the tube knob I have it set at about 12 o clock, the sound I get I'm really quite happy with, that classic Ampeg sound but I just think for the power output it has I should have a bit more left in the bank. I haven't made much use of the eq though which I may try, any tips on settings (really like that JJ Burnel, Bruce Foxton Sound)? That maybe the answer. I have had a look at the Ashdown and Markbass gear looks pretty good!
Mike
