VOP-9 Vintage Overdrive Pro

The VOP-9 Vintage Overdrive Pro by Maxon is a versatile pedal designed for guitarists seeking warm, smooth overdrive tones without compromising the natural characteristics of their guitar and amp setup. The pedal features an internal charge pump that allows for switchable 9 or 18-volt operation, providing increased headroom and a fuller frequency response at the higher voltage setting.

The pedal's design is based on Maxon's legendary "808" circuit, with a dual- ganged Drive pot that controls the amount of Gain as well as the mix between clean and distorted signals. Additionally, the VOP-9 features a standard 808-style tone control and operates at 18 volts via an internal voltage doubler, providing greater output and a fuller frequency response without the midrange spike typically associated with the 808 circuit.

The VOP-9 Vintage Overdrive Pro is suitable for a wide range of use-cases, from achieving the ultimate blues tone to providing an added push for solos. It has been favored by exceptional guitarists including Scott Henderson, Dave Weiner, Jeff Loomis, Doug Rappoport, and Stuart Ziff.
