wat would anyone reccommend pickup wise? or anything for that matter i have had the guitar for about 3 years now and the parts are rustin, so i thought it might be a good idea to upgrade a little, i dont want a new guitar coz this one plays like a dream, so any suggestions on some upgrades?

and should i get a new amp? i have an ashto GA100 and i think its a bit dodge but i want some feedback so post up!!!
