This thing LOVES dub. Onboard, it features a LF CUT/HF CUT equalization section, four individual volume controls for 4 pairs of delay "taps" (make the third "tap" repeat louder than the second, quieter than the fourth, for example), and even a echo feedback control. This unit, which is the first revision of the design, also doubles as a reverb with a single push-button. It's amazing how cheap this particular one is going for so far on eBay.
