After reading some other posts about how miscellaneous resonance can be picked up by the piezos, I added light foam rubber under the trem springs and that cleared up a lot of the problems. After that, I found that some models sounded decent on all strings and some others now only sounded bad on the low E. That tells me that the problem is in the model. btw, string gauge is 10 and strings are almost new. I actually played this guitar on stage for about a year, just because it played and felt nice and the mag pickups were as good as I've heard on any strat. Even after extensive editing, I never used any of the modeled stuff. Some of it sounded useful but just too much of a hassle to pull up when you're playing live, even if you stick to using only Custom one. Also the tone knob didn't affect both the mags and the models evenly, so a little more hassle switching between those. I'm a long time synth programmer, love my tech, but this isn't for me. Good for some studio work but a version without the mags would be just as good for that. I appreciate the suggestions, thanks.
