I agree this tiny thing rock's.Hard to find vintage sound out of class d amps these days,my tape wound flats,& Peavey mini max v2 head solves all sound issues I have.It has enhanced low end kosmos circuit.My Mini P was fine with stock pups.Tape wound strings and a low end geared amp and good speaker cab make a big difference if you want vintage sound.I think Rumble amps are way over rated,But I'v allways been a Diehard Peavey fan.Just say'in.All lthough I tryed a Rumble 40,It was a good practice amp for a beginner on a budget.
