@lowplaces , this was my problem trying to gig with the 500. Just too woofy and boomy for my taste -- though I am an absolute neophyte when it comes to figuring out the various adjustments on it. It's great in rehearsal but I've not had good luck performance-wise. OTOH my ancient Music Man + 115 EV punches through walls. If anything you have to roll up the bass a bit and dial down the treble/mid.
@jdshimkoski , we aren't ridiculously loud and we try to play at a pretty reasonable volume -- our drummer just gets enthusiastic sometimes...

And one place we play, the stage is just LOUD. That's the one I'm thinking of where the 500 just was not cutting it for me, sound wise. I'd turn it up and more woof-mess, even dialing down the bass etc. Granted, I don't know what I'm doing with it!
Anyway I think I'm going to go ahead and get the 200W, with crossed fingers!
