Hey all, I'm usually lurking in the stomp box area or the diy section of the forum, but today I come over to stratocaster discussion forum to learn some knowledge about swapping bridges between guitars and also some pickup cover information. I have a few Squier Strats, one with black pickguard and covers and the other with white pickguard and covers. One is a HSS bullet as it claims on the headstock and the other I believe is an SSS affinity but I am not positive about the model. Yesterday I went to simply swap the single coil neck pickup covers so that they'd both have black and white pickup cover and I was going to swap the corresponding tone knobs to match. To my surprise they are slightly different sizes! I cannot simply swap the covers. So this made me wonder if the covers do not switch out easily does that mean the bridges would also not fit correctly?? More importantly how can I know when I'm purchasing any of these after-market parts that it will be the appropriate pickup cover or the bridge that pops into place just perfectly or the neck that fits the body just right??? Thank you I advance for any help you might be able to offer me. I hope your all having as good a summer as the times will allow!
