The Monza continues the Dr Z tradition of simple is more. Three knobs, two 12AX7s, a pair of EL84s, and a 5AR4 are all that’s needed. The Monza is a gain and sustain monster. It excels at giving your fingers back what they put in with the feel and response of an amp 5x its power. Chords ring strong while single notes rise and bloom. It’s like harnessing the power and response of a 100 watt stack without clearing the first 20 rows. The term “Billy in a Box” has been used to describe the Monza. It’s that and so much more.

The Monza features Volume, Drive, and Tone controls. This isn’t your traditional master volume set up. The volume controls the overall output while the drive adds more sustain and depth as you turn it up. Notes just keep getting bigger and bigger.

The Monza is available as a head, 1x10, 1x12, and 2x10 combo. The 1x10 features the Red Fang alnico 10 made by Eminence. This is an awesome sounding combination in a very portable package.

Due to the rapid turnover rate of Dr. Z amps, colors will vary, and chances are we probably have more than one of any given amp at any given time in stock
