Does anyone have any experience with finding a decently powered combo amp that is pretty transparent or FRFR, for purposes of amplifying an HX Stomp with amp/speaker models? This would be for rehearsals and likely some gigs with a band that has a loud drummer. I want as close to FRFR as I can get. I know that the QSC or other PA speakers can do a decent job - but I'm concerned that they might not have enough oomph in this scenario - particularly since I play 5 string. Looking for a combo, or even just a small cab recommendation for rehearsals and probably some gigs (as a monitor). Weight is important - the new rehearsal space is.... fun to get into. I'm thinking about the Hartke KB15 for a combo. Should I spring for a QSC K12 instead?
