I have. Either head has enough oomph for any gig I'd ever play, and having a pair of these cabs has always been plenty even for the stupidest stage volumes, but they do sound different of course. The Fusion being warmer and the 800 being more modern/wide/crisp, plus at least until the MBF800 comes out, also more dynamic headroom. My gosh, that thing peaks over 1kW!!Does anyone here run one or two of these with the MB800? I've got a real itch to try that compared to the mb fusion I have through this cab. even better - anyone A/B'd those two heads with this Neo?
Thanks all for such a great thread.
