This appears to be the original design of the "Rum and Coke," a standard model from the brand that continues to be produced with frequent updates. It is serial number #2, assembled with hand-wired (Point to Point) circuitry, and, as the name suggests, is a pedal that recreates the Rams Head era BIG MUFF. I have used it frequently since purchasing it used, including incorporating it into my pedalboard, so it shows considerable signs of use. Please refrain from purchasing if you are concerned about this. Please check the images for details on the accessories and the unit itself.
