Frank many years, stages, and tosses later. Main mods: 

BODY: Number 8 eyehooks for "locking" straps. man, I tried them all, and they all give after enough abuse, but these eyehooks and spring clips take more than any of them. You'll see this mod on a lot of the heavy hitters gits. The rare occasion they break is from a direct hit to the ground. Even then, there's TWO on the bottom side of my guitars. Another functional design: when you set the guitar down and lean it against something, like the amp or a wall,  it doesn't teeter on one central strap peg and fall over. All guitars should have this. I don't know how many "Anniversaries" these guys have to celebrate before they figure it out, but I won't be impressed until they do.

PICKGAURD: On this particular one, ( I have several complete pickgaurd assemblies) there's two Texas Specials (neck and middle) and a DiMarzio Hot Rail in the bridge. They get replaced as I bust them up. But probably you're looking at the crazy "roll bar" over the bottom tone knob. Again, a functional mod to stop my pots from being sheered off so frequently. It hasn't happened since I installed it, which was after I lost the knob you see missing for the volume control . Home Depot saves the day again.
