Clean Bass Preamp.

The Harmonic Booster is derived from the first few gain and filter stages of what would later become the core of the Darkglass overdrive technology. This clean preamp enhances attack and presence while sculpting the mids for a very percussive and aggressive character. It features a unique tone-shaping Character control, as well as a 3-band active EQ with a semi-parametric mid control
