Hi all! I recently bought this "LeGrand" guitar which very much looks like an Altamira guitar and seems to mount (see attached pic) exactly these Altamira tuners: https://www.****.com/product-p/agjdgptm.htm. Now, two of the buttons broke and have been replaced with plastic ones. Since the Gypsy Jazz Deluxe tuners by Altamira in the link above are just 50 USD, I thought about buying one to replace the buttons, but maybe I should directly upgrade the tuners? Any advice/opinion? :) Thanks!
