O.k., got a strange question. Just got a Eden WT800, love it. I play a Spector and Rick and gig with both. When switching between two basses I need to make adjustments to my head for each bass or it sounds like crap, major adjustments. Spector is active Rick is passive, at first glance it should just be a volume issue. Should I have to do that, is that normal? Am I doing something wrong is there a way around this?
