yep it is very quiet on this one.
I would have replied earlier but the first post I read when i was in work and could not reply, the next two I just missed and the third I saw just now while flicking through all the sections to see what i have missed.
My father in law retunes a lot of instruments different. i.e uke to banjo, banjo to madolin etc. not too sure what he does exactly, but he did retune his 4 string banjo to the same as a mandolin and it sounded great.
I think you could experiment in anything and retune anything you want but I would think you might need different stings as the uke strings are different, or swap the strings about?
