I'm hoping to simply use a surround rather than a pickguard.
I don't have a Dremel, and don't have plans to get one. The challenge for me is that I'm a guitarist, not a woodworker, so I can't justify the expense of a Dremel or a router. Also, I'm a terrible woodworker, so I'm afraid that a Dremel would simply be wasted on me anyway.
Electronics are another story - I used to make all my own MIDI cables and patch cables to custom lengths, mainly so I could have a tidy patch bay. So I'm looking forward to the design and soldering of the electronics.
