Well, I play mostly in a church praise band these days. I listened to a tape recently of some of our stuff and the bass was pretty muddy and undefined. I get a nice stage sound, but it just wasn't coming through the PA. This was with Fender Flatwounds, which I really like. So I got a set of Ernie Ball "Hybrid Slinky" (.045-.105) nickel roundwounds and tried that. Now it sounds like I'm playing a bass, and not some sort of tone generator. It's kind of interesting getting used to rounds again. They feel softer to my fingers, and I have to work on eliminating finger noise. Got some GHS Fast Fret, and it helps a lot. The Ernies are almost as thumpy as the Fender flats, and obviously a lot brighter. They sound a little harsh soloed, but sit pretty well in the mix. The Fender flats weren't really the problem, the problem is either PA EQ, or the direct signal I was sending, or something like that. Still, I'm going to use rounds for a while. I've got a set of SIT Rock Brights on the way, and I'm going to try some RS66LDN's as soon as Dude has them in stock.
