The DDR combines the most common guitar effects DRIVE and WET into one pedal. Choose between two classic overdrives and then pour on some delay or reverb. The DRIVE section gives you two styles of overdrive to choose from: Crunch or Lead. The Crunch Style gives you a gritty British tube-amp combo sound. The Lead Style gives you a warm and dark, mid-pushed overdrive. The WET side of the pedal gives you Delays and Reverbs.
