DESCRIPTION:
I started circuit bending this Speak & Read over a year ago, but lost interest in the project... until last week. That's when I decided to finish it off. I even painted it. I so very rarely do that. It must be love, right?

Here's a list of the bends & mods:
1x 'on' repeater switch.
1x tone switch
1x distortion
5x loop/hold switches.
1x glitch switch.
1x master pitch dial.
1x reset button.
Video output.
line output.
line input.
PT2399 delay w/ rate & feedback dials. Overdrive repeats button and slapback switch.
555-based LFO w/ rate, shape & depth dials and blue indicator LED.
2x switches for LFO control of the Speak's pitch and the delay's rate.
TL082 mixer w/ volume dials for the Speak & Read and Input.
386 based amp to drive the speaker w/ 2x distortion/overdrive dials.

I think that's everything.

The Casio SK-1 (well, Concertmate 500) has 21 switches for glitched out beats, an added LTC1799 precision oscillator to control the pitch. A bass boost switch, Drum volume dial, reset button and also a video-output and a whole bunch of flashing LEDs
