The fully threaded saddles fitted on Telecasters from late 50's to late 60's usually don't have a great reputation among players. They are thinner and somewhat cheaper when compared to the brass saddles from the early 50's or the steel saddles from the mid 50's. I have a 1967 Telecaster with 1965-'66 features I'm very happy with. I wanted to try if installing 50's style saddless would have brought any improvement. In particoular I thought that the guitar could have achieved a tad more of warmth, definition and sustain, so to get a bit closer to the tone of my number one guitar, an original vintage blackguard. I bought and installed a set of Rutter's Vintage style brass saddles, famed of being the best 50's repro saddles out there. From the beginning I wasn't quite satisfied with the change but I thought that the new saddles might have used some break-in. Things didn't get much better after a few months and an accurate set-up; the tone became a bit thinner and harsher (which I tried to compensate closing the tone knob), which is about the opposite I was hoping to get as a result. My impressions were absolutely confirmed when I reverted the guitar to the original "infamous" threaded saddles: my Tele came back to a richer, more articulated and even fatter tone. I Wanted to share my experience with you as I'd love to hear if you had similar experiences or any thoughts about this. Of course all of the above is aside of the so-called "intonation issues" of the vintage saddles, which never worried me.
