Considered by many to be the "holy grail" of tube amplifiers, the Dumble Overdrive Special has been coveted by players and collectors alike. This example comes to us from the original owner, and is in "like new" condition. The "boost" channel offers the famous Dumble overdrive; rich and musical, with a tone like nothing else. The amp includes the original footswitch for switching between the clean and overdriven circuit. Like New $115,000.
