I've got a Gretsch 6129 with a Bigsby. I've seen Bigsbys with a string through feature as opposed to mine in which the string ball ends go over the mounting pins. Can the string through rod part be ordered from Bigsby and put on in place of the pin style? Just curious.
do you read music ?
If yes , "the advancing guitarist" Mick Goodrick is excellent and not only for jazz music, it's great to understand a lot of music and guitar.
I spent many, many hours working with this book.
