They recreated the circuits in each pedal staying true to the original, keeping both buffers that were used in the original designs in order to replicate the exact interaction between the two circuits, but added switching options for additional tone shaping.
Side A features the TS10 circuit with external knobs for DRIVE, TONE, LEVEL and a three position toggle switch labeled LOWS. The lows switch changes the bass response of the circuit. Internally you find dip switches (clipping, clarity, brightness and output boost) that further enables you to tweak your tone.
The side B features the K-circuit with external knobs for GAIN, TREBLE, OUTPUT and a two position toggle switch labeled CLIPPING. The clipping switch toggles between a pair of germanium or schottky clipping diodes.
This sick pedal very lightly used, and we'll ship it to you lightning fast in its original box! Feel free to give us a call with any questions you may have about it!
