Just got back from rehearsal, first time I’ve used my RM500 EVO2 with the band and it sounded great, if anything I need to tweak it to reign it in a bit. It was through an Ampeg 810 though.
Shape in, touch of compression & drive. Might either take off the drive or put a set of Rotosound flats on my Precision, reckon for 70s classic rock they should work nicely with the RM.
