Yeah I know it's newish. I've tried all the amps on my list except the Promethean. Sam Ass, Alto Music & Guitar Center by me don't have one. I guess I'm heading to 48th street unless anyone knows a store in NNJ that has one. I'm down to a used SVP Pro or a MB2-500 (no budget for the RH450) but before I pull the trigger I wanna give the Promethean a shot.
