- Low-gain preamplifier pedal for electric bass
- Character knob adds harmonic richness as you turn it up, completely transparent all the way down
- 3-band EQ with parametric mid band for versatile tone shaping
- Clean preamp enhances attack and presence
- Exceptional clean headroom and ultra-low-noise design
The Harmonic Booster was Darkglass Electronics' first effects pedal, a clean bass preamp with a simple, one-knob, one-toggle switch design delivering enhanced attack, sharper presence and punchy mids. But it could be improved upon, and with another decade's worth of R&D and effects and amp building, Darkglass have taken another pass at it, with the Harmonic Booster 2.0 reengineered to give bassists more headroom, less noise, and a comprehensive EQ section for sculpting the tone.
The principal behind the pedal, its function, is unchanged. Like its predecessor, the Harmonic Booster 2.0 is what Darkglass calls a "clean harmonic-excitation preamp", so-called because they chanced upon its effect on clean bass tones when they were experimenting on the gain and filter stages of their overdrive.
