I did Low G on my tenor... although I know it is the classic Tenor scenario, I LOVE IT!!!
It does take a bit to get your brain used to the new sound, but whoa buddy, I LOVE IT! (Did I mention I love it?)
I was playing it last night with a Brandon Flowers song and it just "worked" so well! It is a rock song with a strong bass side of the guitar line. I have a wound G & C which adds an little more low-end. I think it is my preference when it comes to Tenors because when I tried just the one wound Low G, that string really stood out and it seemed off-balance. It may be the combination of tone woods though. It is my Eleuke Prototype Acoustic Cedar/Rosewood. Cedar/Rosewood is loud with such a strong lower end, the 2 wound combination seemed to suit it well. The other nice thing is, if you play it standing up with a strap (the MiSi provides the button) the resonance shakes your whole core. I can't explain it, but it is wonderful. It is like you soul feels the bass! I think it is my new favorite uke because of it (shhhh... don't tell my concert)!
