The Z-28 is back, and better than ever! Longtime Dr. Z fans will remember the original EF-86 based Z-28, and it’s back after a complete bottom up redesign, but that same Dr. Z attention to detail and quality. The redesign brings the now familiar Master Volume/Volume controls that we’ve come to love on the Maz 18/Z-Wreck Jrs, making this MKII build a fantastic stage amp, and also one that works great at bedroom volumes.
