Rusty Relics

what guitar part is the biggest effect on sound (voice?)?
Well years ago I bought a cheap squire start my first guitar – After getting a new guitar I became reckless and it ceased to be cautious until I stored somewhere damp unprotected. it has acquired the cracks of chips and color has disappeared and somehow his party a little rusty. Long Story Short It now appears much. it has that punk / sorta feel relic. However, it still sounds crap. I wonder what parts I need to change to get this wing real and which one party would have the greatest impact. If you can recommend a replacement, it would be wonderful. I hope something usual, which have an enormous impact on the appearance, if not going to try to buy some old. Basically im asking what should I buy to make his squire as a start wing.
