This pedal is part of a complete collection of Maxon pedals with the serial number 001. We are breaking up the set and selling them individually. This pedal is basically brand new and was taken out of its plastic yesterday for the first time to be photographed, never used.

The new AD-9 Pro model improves on one of Maxon’s most coveted models in order to produce the best-sounding, most reliable analog delay ever. Featuring 4 of Maxon’s proprietary MC4107D bucket brigade IC’s, and the world’s first RMS level sensor and companding noise reduction system, the AD-9 Pro delivers 450 millseconds of the most transparent analog delay sound ever available in a stompbox format.
