MOSFET Overdrive & Boost
Perhaps the most versatile OD ever designed for both guitar and bass. MOSFET circuitry delivers tube-like distortion with an independent boost channel. A 3-band EQ with parametric midrange, dry blend, Class A/AB switch, and Bright/Normal switch allow you to dial in the OD tone you've been searching for. Uses 9VDC power supply or single 9V battery.
