Digitech GSP-21 rack unit and foot controller with 23 different adjustable effects that can be combine up to 10 at a time. The GSP-21 Pro from Digitech was revolutionary when first released. 30 years later, rack mounted effects processors with foot controllers are back in fad, and what better way to show others you were ahead of the curve than to show up with one of the originals. Has a speaker simulator, a 7-band equalizer, and stereo imaging to create the perfect tones. This unit is complete, with rack unit, foot switch, power cable, foot controller cable and stereo cable. The unit has some light scratching and wear due to use, but is in proper functioning condition.
