  1. I’ve had the pleasure of owning mine since the early 80s. I loved its seemingly aggressive character initially, but there is a hell of a lot to discover under that industrial skin. Built to last too.

  2. I’ve bought and sold many synthesizers over the years, and this is one of the only ones that I truly regret selling. A truly fantastic synthesizer, with so many sound-design options! If only Korg would re-create it…

  3. i had an 2nd hand juno 106 in the 80’s…probably not a good comparison pricewise but in the demo all the voices sounds the same to me.

  4. I’ve got two of them.. I call them “The Mothers”.. I wonder if someone out there could point me where I could get some replacement keys as one the “Mothers” need some “teeth” replacement
