We have recreated the circuits in each pedal staying true to the original, but added switching options for additional tone shaping. We have kept both buffers that were used in the original designs in order to replicate the exact interaction between the two circuits. The Gravity overdrive is divided into a side A (left) and a side B (right), separated by the order toggle switch in the middle which is used to flip the internal order of the effects and hence the signal path from guitar to amp.
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 three sets of dip switches (clipping, clarity and brightness) 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.
Both sides can be used separately or stacked.
