Darkglass Electronics launch the Harmonic Booster 2.0

November 1, 2019

Audio Distribution Group, distributors of Darkglass Electronics, have today announced the launch of the Harmonic Booster 2.0 Clean Bass Preamp/ Boost Pedal.

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,” state DG! “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.”
