You should go further, leeneia: it's a worked example that a good musician can probably get something out of a rubber band stretched across a tea-tray, and that ukes as they stand have a technical problem, deficient tone because they're not designed for tight stringing. On occasion he got something halfway approaching a decent tone from it, but he could not mask the tendency to buzz - if that's the name for something so slack - and sound like a bee in porridge.
The thread suggested earlier that they have things in common with the baroque guitar. Only size: the guitar has bracing to take better strings and that gives tone.
You might argue that it's what it is: I'd argue that if so, then it should be left where it is and not find its way into performance. Fun, perhaps, but nothing more.
The same might be said of many early instruments, but as we now know how to do it, there's really no excuse not to. And now, permit me to get back to my bowed psaltery...
