Harmonic Booster 2.0
The mythical design that started it all is back!
The Harmonic Booster was our first design ever.
In our quest to design the perfect bass distortion, first, we had to
master the control of harmonics and filtering, which are crucial
to sculpting the character and texture of a distortion circuit at
It was then when testing the first few gain and filter stages of
what would later become the core of our overdrive technology
that we realized that the harmonic excitation circuitry could yield
amazing results on a clean signal at lower gain levels!
The result was a clean preamplifier that enhances attack and
presence while sculpting the mids for a very percussive and
We have picked up a few tricks over the past decade, which
translates into several improvements over the original design:
aside from comprehensive EQ for additional flexibility, noise
performance and headroom are vastly improved in v2.0.
The unique tone-shaping engine can be controlled with the
Character knob, which at minimum leaves your signal
completely flat, providing absolute control from subtle to
Along with this, we have a 3-band active equalizer with our
staple bass and treble knobs, but for the first time in Darkglass
history, featuring a semi-parametric mid control!
And although it is designed to be the perfect complement to our
distortion circuits, its incredible flexibility and portability make it
the perfect one-stop solution for gigging musicians in search of
a precise, and harmonically rich clean preamplifier.

Character: Allows blending in the perfect amount of the
tone-shaping circuitry. It can be set counter-clockwise for a
flatter frequency response.
Mid gain: +-20dB at the frequency selected by "Mid
Mid Frequency: Mid frequency from 250Hz to 2.5kHz.
