| Why not play it first and see if anything needs to be changed? You may like it like it is. It's not necessary to change anything on them.
New pots and a shielding job should cost you around $30.00-$40.00 if a tech does it or a lot less if you do it yourself.
If you're planning on getting a real Fender Geddy neck, just be aware that the SX necks are a bit wider so that the neck pocket will be larger.
