Ok, here's the deal. I dig the tone that I'm getting through my Markbass F500 but I want it to be fatter. I usually have the bass, low mid (@ ~250Hz), and hi mid (@ ~700Hz) set to about 2 o'clock. My bass is pretty bright naturally but when I run it through my computer (flat, no preamp, no amp sim) it sounds HUGE but when I but it through my rig and have to tweak quite a bit to get there. The F500 EQ seems kind of weak in comparison to other preamp EQs (on amps and in basses) that I've tried and I'd like something with more toneshapping power or something that gets me closer to the sound I'm looking for without tweaking. Of course, the easiest way to fix this would be to get a new cab but I really like the mid and treble characteristics of the Berg AE410 so I'd like to keep it. I'm only interested in micro heads. Suggestions?
