I just got off the phone with Mark. My new head is done. He finished it and let it burn in for a while. Now he's just it's going through it & tweaking it some. I can't wait to compare it to my "original" Pure 64 50 watt head!! I already received the 2x12 cab and have been using it with my Komet. Any one else on the board have one on order? Mark is fantastic to deal with. If you're thinking of ordering one I highly reccommend one. Some of the biggest & baddest Blackface style tones around.
