From the vendor
Overview
A light overdrive so transparent it is translucent. It can go from being a nice little eq to a clean boost to pushing your amp into something quite distorted. With its active eq it can thin out the woofiness of humbuckers or add a little girth to single coils.
Controls
• Volume – Controls the output of the effect
• Drive – Adds in drive as you increase the dial
• Bass – When set at noon the bass is flat and clockwise increases and counter clockwise decreases bass.
• Treble – When set at noon the treble is flat and clockwise increases and counter clockwise decreases treble.
Specifications
• Designed for a 125B enclosure with top-mounted jacks
