What a bold move by that person. I guess he didn't mind putting $2,700 on the line but it might have been much simpler and smarter for him to sell the Pa800 when the 61 key Pa2x comes out. His warranty is shot the way it is and I doubt if he could ever sell the thing, or if he does he won't be able to get a good price for it in my opinion because the lack of a warranty and just the not knowing of whether something will go out on it down the road because of the chop shop style modifications done by this unskilled unprofessional person who apparently had no prior experience at doing this sort of thing. Kudos to him if he can indeed sell it at a reasonable price.
Another interesting thing I noticed when the "hood"

was open was that it looked like a veritable ghost town in there. I find it incredible that the Pa800 has the sound quality that it does with the lack of innards it has. And that it costs what it does seeing the lack of quantifiable hardware inside of it.
As a side, when my Tyros warranty ran out over 3 years ago I decided to open it up and have a thorough look inside and inspect things and see if I could somehow correct the button contact issue I was having with some of the panel buttons and I was rather surprised at the sophistication and complexity of what was on the inside. I found out the panel buttons from the inside are protected and encased by plastic coverings (which makes sense since you don't want contact points on the inside shorting with other connections) and so I wasn't able to rectify the issue by spraying contact spray at the connections from the inside. I have had to continue to resort to spraying the contact spray from the outside which does seem to help. But looking at the Pa800 I am amazed by the simplicity and lack of electronics inside of it. I mean honestly, if that guy didn't have his XR rack in there it would probably echo endlessly into the night.

Talk about a cavernous wasteland.

I had to chuckle when the guy said he found out he had enough room to put a rackmount inside of it. I betcha Korg winces at the thought of people gazing at the Pa800's innards or rather lack thereof. $2,700???? Really!?!?!?

At least now I know not to buy one.

PS: I realize that in trying to keep the weight respectable Korg had to do something to make it lighter and I sympathize with them for trying to do that. But my approach has always been to keep the hardware inside of exceptional quality even if that meant a little extra added weight to the keyboard and instead make the actual casing that encases the keyboard of ultra light composite materials to reduce unneccessary weight. Not cut down on the electronics inside of the keyboard to accomplish that very same thing as it seems Korg has done with the Pa800.
Best,
