Roland JD-800


via this auction

"Essentially, this synth is cosmetically a 9.5/10 and functionally an 8/10.
When I received this synth back in 2011, it badly suffered the red glue plague. It did not damage the internals, and I replaced the entire keybed with a brand new one directly from Roland, one of their last ever in stock.
So, the keybed itself functions perfectly. However, the ribbon cable is not perfect and I have clamped it down tonapply more pressure to the contact. Sometimes this resolves the problem, sometimes you have to go in and adjust it again. What happens, when it isn’t behaving correctly, is that some keys will distort, or not play, when in combination with other certain keys. Playing through midi it sounds just fine. But sometimes, playing the keyboard will not play 100%. Apart from this, I recently gave all the sliders and buttons a cleaning with contact cleaner, and given it a good cleaning inside to keep it free from dust.

However, cleaning the sliders didn’t fully resolve parameter jump of 2-3 of the slider controls. It may just mean diving back in and cleaning those sliders another time, worst case scenario is changing out the slider pots..."
