The Korg is a model 500 Micro-Preset. Early 80's. Quirky little thing I put on top of my B-3 in 1980 and used it on a six night a week house job until about 1992. Smoke makes it go out of tune easily. Have to break it down and clean the gold contacts. It's voltage controlled and the corroded contacts cause the out-of-tune problem. Turned it on about a year ago. Worked fine, but...you guessed it...it was out of tune and needed a cleaning.
