Every couple of years I have an open house where I invite the people from the Dr. Z Forum to come and "demo" my Z amps (as well as the Marshalls I also have, if interested). Most of Dr. Z's present line-up will be available along with a number of Dr. Z "Legacy" amps (discontinued models). I am having the open house on Saturday, September 21st from 9-4 ish. In addition, if interested, one of the members opens their rehearsal space for a jam Saturday night with his Z amps. So far, I have 10 or so people from the Z forum that have confirmed their attendance. I live near Ann Arbor. If you are interested, just drop me a line and I can get you an address and directions if need be.
