Hello, I have a 1974 Fender Telecaster Custom, which I believe is the same guitar as yours, more or less. I always felt the pickups seemed somewhat mismatched myself. The neck pickup could get close to a Johnny Winter tone, but the bridge unit never sounded especially tele-ish to me and seemed out of balance with the neck. Two things I have tried: First, I installed a Seymour Duncan Quarter Pounder bridge pickup. This sounded thicker though a bit duller, so it wasn’t moving in the right direction. However, the middle position had a really cool funk tone that the stock pickups couldn’t quite match. Second, I put a wah wah pedal in the signal chain. I got a pretty fat sound by finding a cool tone in the sweep of the pedal and just leaving it there. In addition to these and the other set-up suggestions, I would also consider how many instruments are in your band, and what gear are they using? Maybe you would like to hear more contrast between your sound and theirs. Good luck!
