Stringjoy Signatures 6S Drop Tune Extra Heavy 13-68

"Our Drop 13s take all of the power of our Balanced and Heavy Bottom 13s, but add in a heavier 6th string so that your guitar will be perfectly balanced when you drop the 6th string a whole step. Say goodbye to floppy bottom end—things are about to get heavy.

This set is particularly well-suited for players who favor Drop G or Drop A, but can also be used for Drop B if you like a particularly heavy set or Drop F/F# if you like thinks a touch on the flexible side."
