Signatures on a Ukulele

I have a simple question.IF i have many signatures on my ukulele will that affect anything about it, will it dappen the sound or any other effects, would you not reccomend it? anything about this would be incredibly usefull

I highly doubt it will affect the sound. I have jake's signature on the back of my kanilea tenor near the neck. And I had it done in industrial strength sharpie which is different from regular sharpie as it leaves probably like a fraction of a milimeter thick of ink rather than lying mostly flat. Difficult to describe, but this sharpie goes on more like a super permenant layer of paint. And it doesn't affect the sound at all. If you get a lot of them in regular sharpie, I still doubt that it will affect the sound. Mostly it's the asthetics, if you like having many scattered markings around on your uke.

doesnt effect David's uke, that i know of.
and he has it signed twice by Jake

Don't use fingerpaints
