The thing to remember is that 9V batteries don't like the constant vibration and tend to fail in such circumstances. Pedals that are welded to a beater should be driven by a DC adapter. This will also cut down on weight and allow for faster playing.
Anyways, I guess I will get the used 2002c, grow familiar with it, then try out a demon drive in a shop and see if it's an improvement.
Thanks for the advice, guys!
