So I am playing a Sandberg California (P and MM pickups) through a Hartke HA3500 and two Hydrive 112s and I'm not really happy with what's coming out. To me it kind of sounds like wet cardboard - boomy bass and thin sterile highs. I have the tweeters turned off and the Hydrives stacked on each other and on a box, so they are ear level. The bass knob is usually turned down a bit. Before I got the Hydrives I used an Orange 115 and a I still own an Ashdown Mag 300 with pretty much the same results. I play with my fingers and use Pressurewound. Does anybody have any ideas what to try and do to get a "livelier", growler sound, and how to reduce boomyness without losing the bass itself?
