I put these on my Fender Player Plus Telecaster to replace the stock steel saddles. First of all, I was very impressed with the quality of the machining. The saddles are machined smooth and precise. The grub screws thread perfectly and feel very high quality. The brass definitely added a wider frequency range. The stock steel saddles had a nice ring to them, but these brass saddles have beautiful overtones. The bass is more present, the mids are softer, and the highs are sweeter. I can't recommend enough!!
