From the vendor
The quintessential Maxon overdrive pedal – often imitated but never matched. Identical to the original circuit and featuring the JRC4558 IC chip, the Maxon OD808 reissue offers the smooth, natural overdrive of a full-up tube amplifier in a compact pedal. Incredibly dynamic, the Maxon OD808 pedal responds precisely to playing nuances and allows your instrument’s natural tone to shine through.
