Dr. Z Z-Plus

The Dr. Z -PLUS is a parallel, single-end amplifier in true Class A configuration, which yields a rich clean tone that smoothly overdrives into gritty, harmonic-laden distortion. Single-ended, Class A operation produces full even-order harmonics which are typically cancelled in traditional push-pull, Class A/B tube amp designs. The result is sparkling and satisfying tone with the full range of 2nd and 4th order harmonics with clarity akin to an full bodied, acoustic guitar. While typically class A designs are limited by lower clean headroom, the Z-PLUS utilizes two 6V6 power tubes in parallel with the second amplifying the first, which increases clean headroom, per Joe Walsh’s request.
