Here's what Marshall say about the ShredMaster Reissue Distortion Pedal:

The original Shredmaster was our first ever high-gain pedal and has become synonymous with game-changing music throughout the 90s and beyond. The ultimate care has been taken to ensure that this reissue accurately recreates that iconic Shredmaster sound. The pedal casing is accurately modelled on the bespoke design of the original. The gold Shredmaster name, embossed Marshall logo and the heavy-duty casing are all right here, exactly as you’d expect.
