I've been wanting to (well . . . mostly my back has been demanding that I) convert my Mark IV combo to a head for some time. I actually like the sound of the open-back, wide-body combo, but I just couldn't keep lifting it in and out of trunks much longer. So I asked GTS to build me a black/wicker head shell. I can't get over how much more luggable my amp is now. Here she is in her new home. It also looks like I have a wide body combo shell to sell.
