If this is in the wrong place or you can point me to an answer that already exists, please feel free. I have a Fender Geddy Lee Jazz and it's a real drag to always have to take the pickguard off every time the truss needs an adjustment. What I'd like to do is rout an access groove in the pickguard. I'm concerned that, being plastic, it would be pretty easy to do something that overheats it and causes a warp or crack. In addition to the stock guard (which I'd just as soon leave that way), I have a very nice tort guard (listed as "celluloid" material where I got it) which is currently on there and I the one I want to rout. I also have a black pearl guard that I'm happy to use as a "practice run". Any suggestions for tools and techniques?
