Recently got my grubby mits on that offer too, but with 2 410s gotta say markedly impressed with the cabs, very nice and can go damn loud! The head itself is very flexible and very tweakable, but simple too. Only down side, no footswitch option for the pre sets.
One thing I'm trying to get my head around... The head is a 4ohm but it is advertised, and indeed does work with, a pair of 4ohm cabs. Which means it puts out, theoretically, 1kw. It does appear to be doubly as loud when going from 1 to a pair. Going from 6 to 3 on the master volume during rehearsal. Just wondering what hocus pocus is being performed in side that head
