Back before Radioshack went down the drain they were doing some interesting repackaging work. A large number of the Casio keyboards were also sold by Radioshack under the guise of the "concertmate" series. This keyboard is a Casio SA-5, sold by Radioshack as the "Realistic Concertmate-380."

Modifications:

Glitch trigger button • Glitch trigger button with variable depth knob • Touch contacts for glitch triggering • Heavy squealing distortion knob • Crunchy buzzy distortion switch • Button for slowing the sounds of the keyboard • Body contact for bringing keyboard back to normal speed • Sound reactant LEDs • Volume knob

One of the very first things I ever circuit bent right after learning to solder and buying a cheap iron at 17. Like the Concertmate-380 above, this keyboard (Realistic Concertmate-370) is the Radioshack brand clone of a Casio keyboard. In this case, the Casio SA-8.

Modifications:

4x Glitch Buttons (one with variable depth knob) • Light crunchy distortion switch • Heavy squealing distortion knob • Hidden voice select switch • 1/8" audio output • Internal speaker on/off • Blue sound reactant/power indicator LED
