Congrats on the JBL's Charlie. The thing I like about them is their fantastic bass and clean highs, even at lower volumes. Crown designs great amps and JBL designs great speakers. Hard to beat. With the amount of tone control you have, you should be able to dial in a good stereo sound just for listening also. Then set them back relatively flat for mixing. My bet is that you're well set for a good long while.

I'd be completely happy if I had just one more guitar.
