I bought a telecaster about 14 years ago because I picked it up at the store and loved it. It was my main axe for many years but not anymore. I was told it was an 89 model and I got it for $800, but a few months ago I looked up the serial number & it turned out to be a 79 model. When I first got it I did some changing. I probably wouldn't have if I had known it was a 79. THe pickups were microphonic and so I had them changed. I needed more beef in the neck for solos, so my tech suggested reaplcing the neck single coil with a some type of Gibson humbucker. Also, the 3 saddle bridge was replaced with one that would intonate better. Recently I have had problems getting it set up correctly and it just doesn't sound very "alive" Seems like I keep running in to dead spots. Do I need new frets? Also, the hunbucker sounds real muddy. Should I go back to 2 single coils? If so, what would you guys recommend. The one in the bridge right now is some type of SD pickup but I have no way to know the model. Also, would another bridge wake this guitar up some? Help!
