"This MG-1 has had the switches and sliders replaced with new parts and a synhouse midijack installed. Although this has been with me for some time, I can't say that I've used it much at all. I played this MG-1 for about a half hour prior to listing it including several minutes of midi playing and everything seems to function properly - it's really awesome to have the sliders glide smoothly. All the keys trigger nicely as well and it's capable of producing classic moog tones. It's very clean cosmetically but it does have scratches on the black keys..."
