The Ultraphonix Overdrive is designed to re-create the overdrive produced by a Dumble™ Overdrive Special amplifier. Using a sample size of four generations of Overdrive Special amplifiers from 1970-1990 to voice and calibrate the pedal, the Ultraphonix is more than able to provide the D*style overdrive to any clean amp platform.
