So, since I started playing back in '95, I've always been a fan of having on-board eq, just for more flexibility. My newest bass (NJBD (New Japanese Bass Day)--Bacchus WOODLINE DX5-AC/E-BGP), though, sounds so good without any eq at all, that I only use the preamp when I slap, which is maybe 10% of my band's show. Granted, the slap eq sounds unreal, but the finger tone opens up and growls noticeably more without the darker tone (compression?) of the eq, and our sound guy says that every note is clear and defined going passive. I can even get close to a Spector "Haz Lab" sound, and I have single-coils now...whaaaa?? It's pretty cool knowing that I hardly use the battery, too. What bass changed your mind to go passive?
