I play in a 3-piece punk/indie band. I usually use an Ashdown amp but during recent support gigs I have been forced to use Trace Elliot's. Basically, despite the fact that the tone was turned down on my bass and the high was turned down on the amp my sound was still incredibly high pitched. I am just wondering does the problem here lie with my bass, the sound engineer or the amp itself. Any advice would be much appreciated, I have only been playing a year and a half and often struggle to recreate my jamming sound when on stage.
