Although the name suggests nothing to do with 12 string guitars. my first "new" guitar was a Stella 12 string which had a short neck (12 frets) no truss rod and an action that needed vice like fingers to play. The sound it produced was great although the tuning did sometimes leave a bit to be desired.
I then bought a japanese 12 string which eventually succumbed to a badly warped neck although a great sound impssible to keep in tune.
About 2 years ago, I found a Washbourn cut away 12string, tuned to concert pitch with an action to dream of. Hardly ever goes out of tune and capo's well.I still play this one regularly and it has a place amongst all my banjos.
I agree with former comments, that the 12 string is a special instrument in its own right. I have never regarded it a just another guitar with extra strings.
PS I met Stan Francis a while back on a visit to Lancashire.
