A few years ago, I spent my life savings (approx. $400 at that time) on a used 1959 Morris 9-String.Her sound is full and rich but not quite so jangly as a 12-string, and the neck is narrower too.
Even better, a few years ago, I strung this guitar with Martin .115's and now she NEVER GOES OUT OF TUNE!!!
Well, I mean if you stick her in the trunk of a car and take her out 2 hours later and change the temperature, she might slide a little, but wouldn't you? Realistically, I only have to check the tuning once every 2 weeks or so.
I love this guitar. She's the best stringed instrument in the world. (at least, that I've ever seen.)
