I know nothing about them but my son is in the process of making a mandalin and electric guitar. Don't know if he has used a kit for any instrument he has made or making. He has made all the jigs himself as far as I know for cutting the forms etc.
Blues Creek Guitars offers some of the best kits around. I've built a half dozen of his guitars kits. Go to http://www.kitguitarsforum.com for any help or info you need on acoustic guitar kit construction.
