Thank you for viewing. This is a bridge for a 4-string bass. It was originally on a Fernandes MM type bass (like the Red Hot Chili Peppers' Flea bass?). There is some aging, wear, and scratches, but it's in good condition considering its age. How about using it as a replacement for your Fernandes bass?
