I got a bass I am really happy with, fantastic to play, and after I installed a P/J pair of EMG Geezer Butler pickups in it have close to near my ideal tone as well. An Ibanez Mikro bass that I was lucky had perfectly leveled frets from stock and possible the most stable neck I ever had on any guitar or bass. It sounds amazing through my tube preamp and an 8 band graphic EQ that I use to adjust the tone slightly, going through my old transistor amp and a 2 X 10" cab with tweeter. I don't know how it could possibly sound any better really, very close to ideal for me. Yet I can't help but keep feeling the urge to look for alternative basses, pickups, preamps and amps. Don't really know what it is I am hoping will improve, as I, as said, am really happy with the playability and tone of my bass and rig, and never sounded better. But apparently that doesn't help my GAS. I guess I am lucky to be relatively poor, which prevents me from acquiring a lot of gear I would likely find wouldn't be any improvement at all, probably ending up in a drawer or a corner of my apartment unused, and forced to really think things through before I buy anything new. Anyone familiar with this irrational affliction? I could understand it if I wasn't actually perfectly happy with the tone and playability of my bass and rig, but as it is it just doesn't seem to make any sense to me.
