I suppose five minutes of masking carefully and one could plastidip spray the piano black to any color they like, such as matte black, cheaply. And if it got scratched, it's easy to redo or remove.
This is an interesting approach. I was always focused on an obeche sticker, but that seems too impossible to find. A CF sticker seems easy. Can anyone with this console with some experience with these type things see if it is reasonable? Even easier, what about a black matte skin???
