The Karma Amps Machine Shop is a dual overdrive/distortion pedal combining the ODR-10 and MTN-10 circuits. Each side can be used independently, stacked in series, or blended in parallel. The pedal includes separate controls, true bypass, and a Hold-for-Boost gain function. It features a programmable power-up state and a pure analog signal path. Stack or blend modes are switchable on the front panel. The pedal runs on 9–18 V DC power.
