Mandola: (Tenor) scale length around 420mm
Tuning:  Accepted tuning for mandolins is the same as violins, CGDA from low to high,  with unison strings, that is, with pairs of strings in the same octave. Unfortunately I haven't tried out all these string sets yet. I tend to use GHS bright bronze, but for a typical mandola scale length, I replace the 2nd string with a 020w, as I find 022 breaks too often.
