I recently bought a Dr. Z Z-28 4x10 combo. I wrote Dr. Z to ask them what the cost would be for a head cabinet for the chassis. I was thinking that I might like the haved the flexibility of using the amp in the original combo, or sticking it in the head cab for use w/ one of my cabs. The contact there wrote me back and said that they don't sell the cabinets separately, other than selling off some scratch-n-dent ones at the end of the year. Do any of y'all know where I might be able to order a cab for the Z-28 chassis? Thanks.
