A used Alexander Jubilee Silver Overdrive pedal in Good condition with some added dots to mark control positions which could likely be removed with a little elbow grease.  Sounds great!

FROM ALEXANDER:

Roaring like a British Lion from Wembley to the Sunset Strip, the Jubilee is ready to melt faces.  Sure, it can do subtle but that's no fun.  Crank it up and rock out.
