"Cat not included!"

"This unit is unexpanded (hence the moderate price)... There are many technical photos of this synth at http://www.loscha.com These pictures are of the actual unit you will be buying.

The power socket has a slightly broken shell, but the plug holds in no problems."

KORG Polysix/Mono-Poly era knobs.
