Next Monday, I’m planning to update the guitar I use for experimenting. It’s a late 90’s MIM Squier. I’m going to put the HH loaded pickguard I acquired a while back. I thick it’s from an old blacktop strat with 5 way switching. What should I use to take out the wood & poly between the current pickups? Not having woodworking experience I’m guessing I should pick up a chisel from Home Depot and just go to it. Cutting/sanding with a Dremel just doesn’t seem right. But other the reading the safety precautions I don’t know much about that either. My Dad at least taught me how to solder. I know a few people will say leave it alone. I have a 2015 American Strat that handles all those duties. This guitar’s lot in life is that I change it quite often. It’s more valuable for messing with than its resale. Oh, yes I will be wearing safety glasses and clamping the body to a table outside to do the work. Thanks.
