The Keeley DDR Drive Delay Reverb pedal offers two overdrive styles in the DRIVE section: Crunch and Lead. Crunch provides a gritty sound reminiscent of a British tube-amp combo, while Lead delivers a warm, dark overdrive with a mid-range boost. The WET side features Delays and Reverbs, with a Vintage/Modern Switch to alternate between Spring & Plate reverb or Analog & Digital Delay. Additionally, it includes a built-in effects loop for inserting effects between the Drive and Wet sections, or for standalone use as your sole pedal.
