The 8500 model is a perfect upgrade or replacement set of saddles for your Gibson Nashville Style Tune-o-Matic bridge dated before 2000.
It will also fit in a Schaller 455/456 bridge as well as bridges marked “Schaller made in Germany” on the underside.
They are a drop-in replacement set to make for an easy install.
Please note: engineered for maximum vibration transfer, TUSQ saddles for electric guitars will add rich bell-like highs and big open lows. Put some “spank” into your tone.
