Cool.
 
I wasn't thinking I invented it... I just finally got around to appreciating the idea.
 
I was watching a Jimi Hendrix video and it looked like he was playing a twelve string minus 3 strings and I thought... aha!
 
The video was blurry so I don't even know if what I thought I saw was really what I saw... but any ways... I got to thinking.

Got to thinking... how about 6 regular strings with 3 doubles on the high side.
 
Kind of like a 12 minus 3 set up.
