After watching many vids and reading many posts I deducted that key dip had be addressed first. I then realized that it is wayyyy too deep in comparison to what is recommended by VV or the og user manual. A pressed key will go down to almost touch the tolex case (before after touch).
So I took out the action out of the case and I don't see hints of shimming, it looks pretty flat and the felt doesn't seem too thick.
With all of that in mind what can be done to fix this deep dip? All I find online if videos of how to fix too shallow dips.
Thanka very much!
