Mike Zaite founded Dr. Z amplifiers out of his basement in 1991. All amplifiers use tube chassis and are wired point-to-point. Dr. Z has produced several different models over the years. Brad Paisley became an endorser in 2001, and Zaite has established a great relationship with him collaborating on several amplifiers including the Stang Ray and Prescription Extra Strength. Head-units, combos, and speaker cabinets are all available, and they come in Black, Blonde, or Red cabinets. For more information, visit Dr. Z's website or contact them directly.
Amplifiers currently produced in Maple Heights, OH, since 1991. Distributed by Dr. Z.
