O.K, One of my "sidelines" is fixing and servicing Amps. This week I had a Trace Elliot 250w Bass combo who's owner was complaing it was "distorting horribly". A quick check out proved it to be nothing more the a corroded output jack (on the back where the internal speakers connect) - Soon sorted with contact cleaner and gentle application of abrasive paper. Trying it out with my AM Standard P Bass it sounded AWFUL - The speakers were "Bottoming" out BADLY. Anyway, as a double check I plugged the P into my Ashdown combo (same cables) - sounded brilliant. I returned the Trace to it's owner who tried it out with his Stingray .... It sounded great! ....one happy chappy. My question is WHY does it sound so awful with a P Bass?
