The Dr. Z Monza (ZA-30) is a 30-watt 6V6-based amplifier that bridges vintage American clean tones with enough gain for expressive breakup. Built in Cleveland by Mike Zaite, it shares the Dr. Z hallmarks of touch sensitivity, musical compression, and warm harmonic character. The Monza suits players who want more headroom than the MAZ series while retaining the same organic, responsive feel.
