So...I burned the midnight oil last night on Gloppy. Here is the play-by-play.
First, took a mouse sander and sanded just deep enough to remove the glop and the super dark stain the previous "restorer" had applied.
Decided not to mess with removing the bridge. Mouse sanded close and then hand-sanded from there. Found the cracks I suspected were there, based on the hit the guitar took to the tail at some point. All are stable and closed.
Then the sides and back. Had to go all the way to bare wood on the sides. Will probably do the same with the back so that they match. Unstained mahogany is beautiful stuff.
The "wood" patch on the tail ended up being putty. It covered way more area than necessary to fix the damage, which is actually pretty minor.
Here is how I left her last night. Free at last!
Plus, the Guild tuners I bought on eBay came in yesterday, so all I need now is a TRC and a Guild silkscreen logo. Next step is to sand the neck and head stock, and try to clean up the interior as best I can. I have decided against using spray can nitro on it. I will hand rub the whole thing with beeswax/carnauba wax/orange oil, put the Guild tuners on, string it with lights and call it a day!
