Boost effect pedal for electric guitar that is ideally suited to pushing the front end of a tube amp. Its J-FET based design delivers up to 20db noiseless gain boost plus optional High Pass or Low Pass filtering to contour the sound. Simple, straight-forward and effective, it remains clean and sweet at all settings and also remains frequency linear as the gain is adjusted, allowing the musician to set the desired level of boost without sacrificing overall tone or requiring them to adjust their amp’s EQ settings to compensate. The pedal sports a simple control layout with a single Volume knob and an oversized toggle switch to select BRIGHT, FLAT or DARK overall frequency response. The BRIGHT mode enables a 3db/octave HP (high pass) filter which is useful for thinning out humbucker guitars when adding boost to increase sparkle and prevent mud. The DARK mode enables a 3db/octave LP (low pass) filter which is useful for fattening up single coil guitars when adding boost, to increase warmth and prevent harshness. The pedal also offers a TRS port for expression pedal control of the VOLUME knob, which turns it into a high-fidelity, active volume pedal with user-adjustable minimum and maximum settings. It has an anodized, brushed-aluminium enclosure, 9V battery or AC powered operation (battery is included), rear-mounted metal jacks and studio-friendly, noiseless true-bypass switching. Dimensions: 80 x 80 x 125 mm. Weight: 0.5 kg.
