Dunlop · pedal
The MXR Randy Rhoads Concorde Distortion, model RR104C, is a signature distortion pedal endorsed by the estate of Randy Rhoads, based on the MXR Distortion Plus circuit that Rhoads used extensively during his tenure with Ozzy Osbourne. The Distortion Plus is fundamental to the Rhoads tone heard on Blizzard of Ozz and Diary of a Madman, where it combined with his modified Marshall amplifiers to produce his iconic British high-gain sound. The Concorde edition features period-accurate specifications and custom cosmetics honoring the Rhoads legacy, and delivers the warm, compressed hard-clipping distortion character of the original MXR Distortion Plus circuit.
