Here is a post and comment by the Doc on MAZ 38 versions. Note that this is a Apr 16, 2012 quote. Other updates can be viewed on Dr. Z Amps Mods & Services page. drzamps.com/support/mods-and-services/
Version 1: 1990 to appox 1999 Original MAZ's were named ( i.e. Invasion, Studio Deluxe, Studio Lead , and so on ) they had Vertical input jacks, negative feedback, and a Presence control, a bit on the cleaner side.
Version 2 : 2000 to 2010 Horizontal input jacks, hotter PI with no NFB, a CUT control, and now all called MAZ Seniors. A bit dirtier.
Version 3 : 2011 to Present UL/ETL certified, back to Vert. input jacks, EQ boost and Effects Loop standard, detachable IEC power cords, many tweaks to the tone of the amp, and new Reverb tubs.
