The Octabvre Mini is a modified and miniaturized version of the Octabvre that was designed for bass player and effects guru Tim Lefebvre. It starts with the popular Tim-tuning mod from the original and takes it further with a reworked tone knob that runs the gamut from classic OC-2-inspired thump to all-out sub fuzz. The new tone knob blends together two independent tone circuits. With the tone knob fully counterclockwise, the Octabvre Mini is a functional equivalent of the classic Boss OC-2 Octaver. As the tone knob is turned up, a fuzzy square wave version of the octave down circuit is introduced.
