You will take all those guys' gigs if you play great time and sound great. Sounding great, in general, means a P or a J type. Sorry to the "all music is art" crowd, but playing a bass that has inappropriate frequency response all over the place ain't art. You show up to the gig with a P or J, the sound man will love you. Show up with a dual parametric mids preamp, soapbars, and mahogany EVERYTHING, the sound man will want to murder you. That stuff can sound really cool in the right context, but a working top 40 band is not it.
That's funny, cuz all three of my top 40 bands seem to like my dual soapbar, active, mahogany bass just fine. Fine enough, in fact, to have used me to replace all of their original bassists. Wouldn't have anything to do with my ability and musical taste now, would it?
