Anyone here tried playing this head through a modern cabinet as opposed its old 18" folding horn counterpart? If so, can you describe the results? From what I've heard, this amp has an extremely distorted, low-fi tone, which I've realized might prove useful in some situations (namely, outdoor gigs with two 100-watt marshall stack guitarists.) So how would the amp sound through a much smaller cabinet setup, like a pair of Aguilar 1x12's? Also, is the distortion this head produces more of a result of the preamp, the power section or a combination of both? Does it have an FX loop or any line inputs/outputs so an alternate preamp or poweramp can be used if necessary?
