Just got a 2011 Dr. Z Maz 18 Non Reverb on Reverb- the 2 x 10" version, blonde tolex. Can't wait to get it and try it. This has been my dream amp for years- I've played many and loved every one. And the company is local- I'm in the Cleveland Area. I will update with pix and stuff as I have them. A couple questions: It's got a manufacture date of 11/11. It's got the current cosmetics, but I believe that makes it a "Mark I" I'm getting ahead of myself here, but does anyone know the details on the Dual Gang Master Volume pot on the Mark II (Resistance and layout/connections)? Not sure if I'll mess with it, but I'd be interested in maybe trying the dual gang. Thanks.
