I've got a Ceriatone JTM45 clone head. It's got hardwired 16 ohm output jacks. I read that it would be OK to run the amp into an 8 ohm load though. First, is it really OK to do? I don't want to risk hurting it, it sounds so sweet! Second, what could I expect to hear soundwise? Will it be brighter, darker, looser, tighter?
