The Ultimate Keytar

Who needs a Syntar when you can have this! Click here for more shots via this auction.

Details:
"This is a vintage 80's toy called Hit Guitar. The neck piece straps to your hand allowing you to play a twelve note scale! The guitar part straps to your belt. This strange devise is hard to find and should be circuit bent with a pitch pot so you can tune it fat and low! However it does have a tone knob on it which is actually a tune knob. You can bend the pitch up or down and when you let go of it the note you're playing will snap back to it's original pitch. This has an analog chip in it and will make an excellent stage instrument if it falls in the right hands...I'm only selling this cause I'm swimming in heaps of gear I've collected and something must go! It works well (I played a few farewell solos today) but the battery cover is missing. Snap this gem to bend up if you like it!"

BTW, if you know anything about the "analog chip" feel free to comment. I'm guessing it's not actually analog, but who knows...

Inside an Oberheim OB-Mx

"This Oberheim OB-Mx rackmount analog synth was purchased new in 1995 and was played by Rick Wakeman on the YES album "Keys to Ascension" (I was a recording engineer on the project). It has three (3) voice expansion cards, and has been in a controlled storage environment since 1996. Front panel, knobs, LCD, output jacks, etc. are in excellent condition. The memory backup battery expired some time ago, and as a result, all internal presets are lost/scrambled. I do not have a users manual or any documentation. ROM version is 1.04."

AY-3-8910A Synth Sound Efx Chip

"This is a AY-3-8910A Synth Sound Efx Chip used in a LOT of old school coin-op video games. It is NOS (New-Old Stock), and comes with all documentation and Datasheets. It is a pretty wild chip - 3 oscillators, 1 noise generator, envelope controls, and 3 mixers, all under CPU control. (it is a register-based chip)."
