What’s the common things to all these guitars?
I fitted all of them with amazing Wilkinson Direct WLS 130 locking saddles!
No matter if it’s standard Fender 2 point tremolo, 6 screws vintage tremolo, Gotoh 510 – they fit them all with simple replacement as removing stock ones and putting those straight in!
So, If You are a heavy bender (4-5 semitons up) and tremolo user – IMHO, these are the only solution at the moment to keep Your non locking tremolo in perfect tuning – especially those 3rd and 6th string.
