This is my first post on here... My high school recently received a generous donation- A fender American Jazz '77. Black body/Black pickguard, real beauty (says the amateur). However I was wondering why the bridge pickup seems like it has extra space around it (like a large slot). I'll post pictures in a while, but for now maybe an answer? I was wondering if it's normal or if any previous owners changed the original pups? -Thanks ahead of time.
