Dang, I was just about to write a cuatro megapost; I just sold one on Craigslist in DC a few weeks ago too.



So far as odd tuner readings, are you plucking both strings at the same time or just one from each pair? Multiple strings confuse the tuners, so if you have doubled strings, tune one and then the other. Notice too that on some courses (pairs) they have a high-octave and a low-octave string, the latter being visibly much fatter, so just note that they'll have the same note, but an octave apart.

Other than that, cuatro should have a string tension vaguely similar to a guitar, so if you're getting an "E" and your string is incredibly floppy, you may be an octave too low. The strings should be reasonably firm with a little yield, but not feel like they're rigid.

Does that sort of answer your question, or is your problem a bit different?
