So, anyone use one of these. It's being supplied as part of the backline for a showcase at NxNE I'm playing in a cupla weeks. I've never even heard of this head before but from the brief specs at the Marshall site it sounds interesting. 8 6550 power tubes, ECC83 and ECC82 preamp tubes, 400 watts of power. The question is do I assume I can get a good tone from this amp or do I lug my old SVT to the show instead.
