Yes you read it right, i am very fascinated by this and my search for information about it hasnt been very productive. This is how Hagstrom used to make some of their guitars back in '59
Funny enough i just has an idea right after clicking submit reply, those stickers that look like peraloid might work, but what im really intrigued about this is that it might have been done with pickguard plastic.
Im not a builder, just an aficionado who is interested in manufacturing guitars so i dont know anything about where to buy materials or anything so im pretty much looking for direntions here
