The Bows is a Germanium preamp designed around a rare NOS OC139 black glass transistor. For being a little one-knobber the Bows wears many hats. Right out of the box it’s got several tone shaping abilities spread between two modes: Full and Treble. Full mode is warm with a lot of body and low end. Treble mode is a resonant, treble booster with a ?cocked wah? tone that can drive any tube amp into harmonic rich distortion territory. Each mode has a little bit of grit to start with, but as you get passed 12 o’clock on either setting their subtleties are accented.
