The Ultraphonix Overdrive is designed to re-create the legendary overdrive of the Dumble Overdrive Special amplifier.

Four Overdrive Specials were used in the voicing and calibration of the Ultraphonix, each amp ranging in origin from the years 1970-1990.

The Ultraphonix is more than able to provide the Dumble-style overdrive in front of any clean amp platform!

Or, engage the Ultraphonix in front of a broken-up amp to really cut through the mix with a huge lead tone.

The pedal easily re-creates the legendary fat overdrive, note bloom, and harmonic overtones produced by these ultra-rare boutique amplifiers. 

With just Master Volume, Level, and midrange Filter controls, you have access to an incredible variety of tones from all genres.

Plus, the new MKII version adds a Ratio control for striking the ideal balance between your dry and dirty signals. 

Experience a truly smooth, creamy overdrive for yourself with the Vertex Effects Ultraphonix MK II Overdrive!
