ATHERIS INNOVATIONS
The people at Atheris Innovations make a patented modular pickguard design that allows you to change your pickups and the look of your axe (if you choose) in a matter of minutes. I have one guitar that has 5 different sets of pickups in different configurations that give the guitar completely different voicings while still feeling like the same guitar.
BODEAN STRAPS & PICKUPS
Bodean does very high-quality work. Both in his leatherwork for straps and his pickups. I personally have a custom guitar strap from him as well as two sets of pickups in a couple of my guitars. My wife has ordered a few custom-built items as well.
CALFABRIC
I buy all of my custom etched neck plates here because of their great quality and they can engrave any picture you can send in JPeg form.
