An unconventional combo amp with unique trem/vibrato tones.

Gear reviewers tend to describe new amps in terms of old ones. We rely on stock phrases: “Vox-like chime,” “Blackface-style scoop,” “Marshall-like midrange.” That usually works out fine, because new amps also tend to rely on what’s come before. But comparisons aren’t so easy when confronted with an amp as unique, idiosyncratic, and just plain weird as Siegmund’s massive Doppler combo. I’ve never encountered anything like it, and I bet you haven’t either.

Big and Blingy
The Doppler is an imposing beast, weighing in at 70 pounds—think silverface Fender Twin with JBLs, only more so. Like those Twins, it comes with detachable casters—five of them to suit the amp’s trapezoidal shape. The amp is as wide as it is heavy, measuring an impressive 33.5" from left to right. The cabinet is solid pine. The components are mostly high-end NOS stuff, including most of the tubes, and the circuit is immaculately hand-wired on terminal strip. The transformers are from Mercury Magnetics, with the output transformer a custom model and one tube rectifier.
