Now is that RC booster similar to my Seymour Duncan Pickup booster pedal? ...gives a nice mix of drive to that 5150 regardless I had a Marshall Plexi head which I kick myself for selling years ago but have yet to try a 5150 they don't pass through my way at the local retailers here I'm hoping some guitarist in town has one and puts it up for sale but I know almost everyone in this town so I'll be waiting for awhile I figure...I wouldn't give up my Twin Reverb for all the tea in China but I'd sell my Line6 for one in a heartbeat....great noodle on that track by the way
