Ok so I just got my Cool Rail for my MIM 1994 Strat (SSS). And I was wondering if I need to route the body or make any mods to the body or if I can just pop it in. Also I have been reading some other threads and posts but I`m not sure if I need to install a 500k pot instead of the original 250k pot. This is the first upgrade i do to the electronics. I`m new to all this and I need some help with this. Thanks in advance.
