Yet another, around the 12th RP500 I’ve had and they’ve proven to be my hottest selling floor multi-effect The RP500 is the latest and greatest from Digitech’s RP series. More than just an extremely powerful modeler and multi-effect, the RP500 has an exclusive “pedalboard mode” which changes it into 5 individual stompboxes and effects.
