I would be interested in building a 12 string electric but I don't want an ES-12G, I'm after a solid body.
Lots of different styles out there to choose from, I would like a Tele style but I would happily get whatever was available.
Alternatively, what would be the chances of getting a seperate 12 string neck that would fit on an existing kit? or does the body and neck pocket need to be reinforced to handle the extra string tension?
