Hi there! I own the Squier Avril Lavigne Signature Telecaster, it has got 1 humbucker, 1 volume and a 3-way switch. I'm planning on upgrading the electronic parts with a Switchcraft input jack, a new 500K pot and a 3-way switch - but I have a question... The current wiring is done without a capacitor, so I guess I would just go and do the same, but would it be possible to solder a capacitor to the wiring, and what would it do?? What's the difference? Thanks & Cheers!
