The Seymour Duncan 805 Overdrive uses the same chip found in the legendary 808 as a starting point, but ends with an MC33178. It has an active three-band EQ, glass-diode/back-to-back stack distortion circuit, and a gain-control range of 8dB to 36dB. Wired true-bypass and for AC/DC operation, it is assembled at the Seymour Duncan Factory in California. Visit www.seymourduncan.com.
