When Joe Walsh approached Dr. Z for a new amp to use on the latest Eagles’ tour, Dr. Z took inspiration from the classic Tweed practice amp Walsh used with the James Gang. The Z-Plus is a parallel, single-end amplifier running in true Class A, 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 tube designs. The result is sparkling and satisfying tone with the full range of 2nd and 4th order harmonics akin to an full bodied, acoustic guitar. While most class A designs suffer from limited clean headroom, the Z-PLUS utilizes two 6V6 power tubes in parallel for extra power and headroom.
The half-power switch drops the second 6V6 out of operation, rewarding you with touch responsive drive, dynamic compression, and lowered headroom. This is not your typical one-knob, single ended amp. It includes full, 3-band EQ with master volume and cut, hi and lo sensitivity inputs, an effects loop, a rich reverb circuit, and a foot-switchable variable boost. The special design output transformer is constructed with the highest grade M-6 stacked laminates.
The new Dr. Z Z-Plus is a uniqe boutique combo amplifier--perfect for stage or studio.
