My first guitar was an old Fender Musicmaster. It had a funky old three-saddle bridge, and the saddles were made out of what I can best describe as all-thread. That guitar is long gone, but I woke up this morning wondering two things: 1) Did '70s-era telecasters ever come stock with those saddles, and 2) how do they affect tone? It seems that, depending on the string gauge, the guitar would less-than-ideal contact between the strings and the saddles, creating buzz or muffling issues. Is this true?
