The KEY9 transforms a guitar or keyboard signal into nine keyboard-style sounds: Dynamo, Wurli, Suitcase, Mallets, Eighty Eight, Tri-Glorious, Vibes, Organ and Steel Drums. Separate Dry and Keys volume controls let you blend the original instrument with the effect, while the two CTRL knobs adjust different characteristics for each preset. It also has separate Effect and Dry outputs. This is a digital, mono pedal with buffered bypass, a 100mA current draw and 4.75" × 4" × 2.25" dimensions. It requires a compatible 9.6VDC/200mA power supply. This listing includes the pedal shown; no power supply is pictured. Please review the photo closely for its cosmetic condition.
