One guitar that I really want is a Baritone Jazzmaster with P-90s. No one makes those so I'll have to do it myself. If I do go through with it, is it as easy as putting everything together and just setting it up? I would get the standard Jazzmaster body with a 28 5/8" conversion angled Strat neck. I'll also get a Jazzmaster tailpiece with a modified Mustang bridge. Is there anything I should think about prior to doing this as well as anything that won't work? I don't want to waste $1000+ on an impossible project.
