I have recently bought a Rickenbacker 4003 and an Ashdown ABM 210 500w EVOII combo with Ashdown ABM 115 Extension cab and I'm really disappointed with the sound that I am getting. The volume isn't anywhere near what you would expect. I am unsure whether this is due to the size of the practice room, the amp or the guitar... Or a combination of all 3. I have been considering changing the pickups in the Rickenbacker or swapping it for something like a Fender Precision, but don't know if this will help. I've also considered switching amps, but feel I should get some advise before I waste any more money. I want a really full, fat, deep bass sound that you can feel, rather than a twangy sort of Joy Division sound. The music I play has been compared to Snow Patrol, The National and Explosions In The Sky. Any advise would be much appreciated. Thanks.
