I've an old Fender Highway 1 precision bass (2003) and I'd like to change the tuners (the E tuner don't keep the string in tune too much time...). I've read an old thread that the best/easy replacement for this concrete model are the Hipshot HB7. But The Hipshot HB7 says: FOR FENDER MEX MEXICO. Is it ok? Are this ones for earlier Highway 1 too? Are the Hipshot HB7 way better than the original ones? Thanks.
