Hello, while searching for some info on Black/Whiteguards I noticed that pickguard doesn't have the same distance from bridge plate. This may vary from guitar to guitar. Is that a matter of a sort of 'randomly' bridge placement or pickguards dimension may very from guitar to guitar or year to year? Sometimes that difference is small sometimes look like 5mm or more. Thanks, Al Pic show 2 '54 telly, randomly found on Google.
