Yeah my rig is ABMs, the RM head is my backup. The only real difference in sound is once you get on very big stages, at that point the weight of the ABM sound comes across but in pub sized venues, or regular sized stages with FOH the RM handles it fine. Oh and it’s plenty loud too, not one of those amps that runs out of steam, or at least I’ve not managed to get it to that point. I tend to gig the RM more and more these days.
