Up for sale is my MacBeth Studio Systems M3X that I bought new from Ken MacBeth when he first announced them in 2002. It's a low serial number, 0010, so it's a very early build. I never used it much because life happened. It seriously only has only about 2-3 hours of playing time. I've just had it come back from my synth repair guy, and he replaced both Midi jacks, replaced the external input jack, cleaned every potentiometer and recalibrated the oscillator tuning. It works great now. There are a few scratches on the top rear panel and some scuffs on the bottom, and I have photographed them. These appear to be the only cosmetic issues. I also have the original box and power cord. The synth will be double-boxed for shipping, and the shipping cost includes full insurance.
