Great sounding amp head made by DR Z. This is somewhat based on the '60's black face Fender Amps with the addition of level control pre and post preamp. 4, 8 or 16 ohm speaker load outputs.
I had an enhanced '66 Fender Bandmaster.
This amp sounded better in comparison. More flexible and slightly more modern sounding. Grounding enhanced per DR Z's instruction. No issues.
