I took the strings off for the first time and found that a nail was threaded through the ball end. I'm guessing that whoever did that was thinking it would somehow even out the tension? Talking of which, I love that the bridge is only held on by the tension of the strings, as is the nut, and the bridge cover just slots in on two rough looking pins. The whole thing has a retro soviet feel about it in the same way as Russian vintage synths do (yes, I know its not a Russian guitar, but you know what I'm getting at).
