Spaceman Mercury IV Germanium Harmonic Boost 2010s Silver Edition

The Spaceman Effects Mercury IV was created to give you even more out of what you already love about your sound and to be extremely reactive to your instrument, your pickups and your playing dynamics. It includes a tone-shaping section with independent High and Low toggle switches, which are interactive with the Boost and Harmonic controls. Together you can dial up to 35db of boost, tube-like even-order harmonic distortion, and multiple shades of treble boost, mid boost, bass boost or full boost.
