OK, so maybe this is too much for one thread. Anyway...

I want to set up a spare travel guitar as a ukulele. I plan to install four nylon strings where the D, G, B, and E strings would be. It is for a friend who wants to investigate the uke. So having them on the high (bottom) side of the neck would keep them from having to stretch their fingers alltheway up top on the fretboard. Sounds good? Should there be any problems with this?

AND...once they are done and finally hooked and buy their own uke, I was thinking of turning this little guitar into a six stringer but with three pairs of strings. Sort of mandolin/balalaika/lute kinda thing. Yeah, I'd have to change the slots in the nut. But since I don't play way up on the neck, I could leave the ball end of the strings in place (??). I'm not sure how I would tune it, or what kind of style I would play. But it sounds like fun, eh?

Any thoughts on all this?
