That's super cool!! and regardless of WHAT she chooses...being able to make music with your partner...well that's as good as it gets.
I know Tig bought a short scale bass a while back, I don't think it was too expensive he can pipe in.
I have a gal pal, started playing a full scale bass recently (she does already know a guitar fingerboard fairly well, however) but she's 5'1" 100 lbs.
Another friend of mine plays bass with a giggin band and his carpal tunnel had him in wrist braces for quite a while. He played gigs using some sort of keyboard for bass. It sounded great, although it didn't look quite right. BUT he was making music and pulling his weight with the band.
Good luck Glacies. I hope this proves to be a good time of re-alignment for her, and a good time for the two of you as well.
