Here is my SA-8
This is from memory, so may contain minor errors:
Top Row: Jack out, Volume Knob, Reset button, Internal Speaker on/off, Power Led, 6V power in
Second Row: Feedback Knob, Feedback Amount, 5th (on/off/on), Distortion, Distortion Knob, Glitch, Glitch Knob
Third Row: Cowbell (extra sound), Extra demo 1, Extra Demo 2, Extra Demo 3 (currently incorrectly wired?)
Fourth Row: Hidden sound buttons (allows 100 sounds in conjunction with pre-existing blue buttons - instead of just 25)
This instrument features extensively on my forthcoming track, Vive la Difference, which I hope to release in next few days.
My song using this gadget is now out.
The Casio SA-8 is used in the intro, for a brief moment after the first chorus, and in the bridge/solo section after the 2nd verse. The bent sounds used are the feedback, the "sampled percussion" hidden sound patch with distortion (which doesn't sound like any percussion I've ever heard before), and, of course, cowbell (normally a hidden sound on the SA-8).
I will warn you before listening, it contains some swearing, so please don't listen if offended by this.
