The Drunk Beaver Olbia is a high-headroom overdrive based on the Centaur circuit, refined for greater clarity and tonal flexibility. It runs internally at 15 volts for increased headroom and an open, uncompressed feel. Modern power circuitry ensures quiet performance with no charge-pump noise. Its unique clipping sequence combines a red LED and NOS Soviet D2 diodes for rich, complex harmonics. Independent overdrive and clean blend controls allow precise signal mixing. An active three-band EQ completes the design for full-range tone shaping and versatility.
