Does anybody have gigging experience with these two amps? I'm basically wondering about the difference between the all-tube GROWL and the classic Trace GRIND when playing at gig volumes. Both seem to provide aggressive mids and punch - thoughts anyone? I've been reading the YBA200 threads -extensively- and I'm still left wondering if I'll get enough mids for my liking even after all the literature about the tone-stack on this amp. With the Trace, I kinda like the idea of putting a touch of my Fulltone Bassdrive in the High-Pass FX loop. I play either a Fender Jazz or a Ric 4003 and like aggressive mids and a touch of overdrive. Thanks!
