im a bit concerned the retro 30 combined with the reaper might be too bright with the peavy classic 30.as the reaper already is pretty bright by itself in this amp. the extension cab i would be using is a peavy 1 x 12 closed back cab.a panel can be removed to make it partialy open also.is there a wgs speaker that would pair with the reaper and no make the overall sound too bright?
