Last year I bought a 1989 Korean Telecaster which needed a bit of cosmetic touching up. That's done. But do I change the electrics and pickups? I have bought a Fender Kit to change the switches, pot's and wiring and I was thinking of putting some Noiseless Pickups in it. The ones in the guitar work though the electrics are a bit crackly. What do people think? Keep it original? Mod it?
