hahaha... it may take a little bit longer then an hour... the first hour will be spent "what the f*ck what I thinking!"
Tele pocket is different from the Jagstang, so you'll either fill the pocket and start from scratch, or push the Tele neck further into the Jagstang body... have to cut the pickguard to fit around the neck. Fill the tremolo route, move the whole tail back. Reroute & drill for the tail. Then you got a gap between the pickguard and tremolo... gotta make a one off guard. Hopefully the Tele neck is about the same width at the neck pocket, if it's wider, the neck will hang out the neck pocket by a 1/16" to 1/8"... who knows.
