We have a complete collection of Maxon pedals that were released in early 2010's that all have serial numbers ending in 001. We are breaking up the collection and now selling them off individually. This pedal was removed from its box and plastic today to be photographed, it is in brand new condition Includes original box and paperwork, never used.

The Nine Series Overdrive Pro+ takes Maxon’s classic OD-9 circuit and serves it up with two side orders of Whoop-Ass in the form of 9/18 volt operation and a Mid Boost switch.

In 9-volt setting the Pro+ sounds and functions like the standard OD-9 with the added option of a healthy +3 dB of midrange boost at approximately 800 Hz (actual frequency is dependent on Control settings) – great for cutting through a band during solos.

When set to 18-volts the OD-9 Pro+ becomes an 800-pound Gorilla, offering up beefier lows, tighter saturation, improved dynamics and a chunky, aggressive pick attack that will make your amp sound and feel like it just took a Viagra.  Switch on the Mid Boost in this mode and let your solos breathe fire.
