eBay, forever the place to find the most random of items, has listed a one of a kind guitar - and it's not just some special edition Fender. It is in fact a stringless, guitar synthesiser.
In place of the frets and strings are buttons. In the base of the guitar is a syntesiser unit which you can see through plexiglass, with which you can do various... things... to the sound.
Bidding starts at $5000US.
