Hey Tr4f1ka, are you by any chance from Croatia? I think I've seen the same question asked on some Croatian forum just a couple of days ago. Or it's just me imaging things again
Anyway, if you don't find anything, you can easily make your own plans using Corel Draw or some similar program. PM me if you need any help about that. That's how I made the plans for the two guitars I'm building and they turned out to be excellent (the plans, not the guitar, I haven't finished them yet hehe).
