Hi everyone! I think I've decided to get a Avatar 1x12, some kind of power amp, and a preamp...maybe a 2x10 instead...either way I plan on adding a 1x15 or 18 later. I have two questions. 2x10 or 1x12? And can I use my digitech RP200 multieffects pedal as my preamp directly into the poweramp? Will that put too much strain on the poweramp or clip and hurt the speakers? I don't know how much it amplifies my signal, and I don't know how much a rackmounted preamp amplifies a signal, but I do know that my pedal definetly increases my signal cuz my bass gets way louder when I crank that pedal when the amp and bass are set up the same. Any help is much appreciated.
