I've heard many things about fender bullets, like how they increase sustain and have better intonation due to increased contact with the bridge, but I've also heard that they don't do squat unless you're playing an old strat with a tremolo bridge. I have used them before, but I have not done a direct comparison. They seemed the same as my Ernie Ball super slinkies to me. Any opinions? I have a '66 tele with original bridge.
