Classic Audio Transponder Digital Delay - PresetThe Transponder delay is our take on the classic delay pedal. The Transponder features crystal clear repeats with delay times up to 1000ms. With the Transponder tap version you get the same great sound of the roller version but instead get the added benefit of being able to save and recall 5 presets. Additionally the Preset version has on board tap tempo so the perfect tempo is only a tap away.
