I'm not askig for too much, just a nice clear defined sound down to E at gig volumes. I'm losing the tone I like below A sharp on the E string. Is it my avatar neo 410 @ 4 ohms, my gk700rbII, or the Squire Tele bass that's to blame. I thought the avatar should handle a low B, but it's not really even getting to E. What component would you replace first?
