Help me decide please! I'm about to make a major amp purchase here. I've heard Nothing but praise about the SVT VR and it being the standard for all bass amps. The SVT7 pro however has me interested too with it being much more affordable. I'll run either Through an Ampeg 810 AV cabinet. We'll be doing both large inside and outside venues. Any thoughts or help you can give this confused novice bass player would be very much appreciated.
