It seemed like the parts of the body that hadn't been modified were close to stock, so maybe I could graft on some horns and get the body back in order?

While I was waiting for it to arrive in the mail, I put together an overlay in photoshop to try and figure out what was going on under all of the mods.

It felt kinda heavy for such a mangled body, so I put it on the scale:

Huh - that's a whoooooooole lotta plastic wood!

...at least the putty popped out of the rhythm control cavity without too much fuss. The putty is incredibly dense! And, it looks like wood, since the p.o. added it in several layers to properly mess up the Jazzmaster.

I used an old brass shield to see about where the wood might be, if any wood was to be found under the putty.

...made some marker lines...

...and it's all pretty much crude dowels and putty...

It looks like some sort of primitive mud-and-stick construction method.

Almost all of the putty is gone, and we've lost quite a bit of weight!

No paint, and a few ounces less.

Nothing to see here, just a couple nails sticking out the side of a guitar body.

Tomorrow I'll try and clean up this carcass and make some spaces to glue some alder rectangles onto
