Any one try the V-wah on bass, it sounds too good to be true. I was at the valley forge guitar show and the roland rep had one. BUT the bastard wouldnt let me try it on bass. HE WAS SUCH A PRICK! It sounded really good on guitar through head phones and a roland practice amp. the tremelo was decent and the pedal sweep adjustment knob was really nice. Built like a tank. I dont want to drop $150 on it and hate it. No music stores around here will stock it.
