Darkglass Harmonic Booster V2 Clean Boost/Preamp Pedal

inc. VAT ex. VAT

Introducing the Darkglass Harmonic Booster 2.0 Clean Booster/Preamp pedal.

The original Harmonic Booster was Darkglass Electronics' first ever pedal design. Now with the Harmonic Booster 2.0 the mythical product that started it all is back, but with major improvements over the original.

In the quest to design the perfect bass distortion, you first have to master the control of harmonics and filtering, which are crucial to sculpting the character and texture of a distortion circuit at will. It was when testing the first few gain and filter stages of what would later become the core of Darkglass' overdrive technology, that it was realised 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 aggressive character and now rare examples of this early design are highly sought after.

Darkglass Electronics has picked up a few tricks over the past decade, which translates into several improvements over the original design. Aside from a new comprehensive EQ section for additional flexibility, noise performance and headroom are all 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 extreme enhancement. In addition, the new 3-band active equalizer, with bass and treble knobs, also features a semi-parametric mid control – a first for Darkglass!

Although Harmonic Booster 2.0 is designed to be the perfect complement to the line-up of Darkglass distortion circuits, its incredible flexibility and portability makes it the perfect one-stop solution for gigging musicians in search of a precise, yet harmonically rich clean preamplifier.
