I recently plunged and finally purchased my first vintage guitar, a left-handed 1960-61 telecaster and mostly original condition. The guitar plays and sounds great. The bridge pickup is microphonic particularly to touch (tapping the guitar, even turning the volume up all the way creates a "click"). That being said, it sounds great. Not sure if potting it will help, but I'd prefer not to have to switch it out. The other question is the pickguard only has the 5 screws and is buckling up a bit on the top and bottom. I see many 1960's with 7 screws. Will putting extra screws affect the value of the guitar? Thanks in advance for any advice.
