Warmoth Pickguard on a Squire Strat
It fit the body contours, neck and bridge perfectly, but the holes weren't lined up with the holes in the body.
Also, the bridge Humbucker route was a bit more towards the bridge than the rout in the body.
I had to remove some wood in that area to reposition the pickup to match the route in the pickguard.
I do not call this a flaw of the pickguard, since there is some variation from model to model, especially Fender/Squire stuff.
The pups and controls fit very precice and neat.
