I have 2 sets of "brand new" (near 2 months old) Roscoe Set that I purchase directly from Gard @ Roscoe Guitars. These strings are great and the same custom gauge/brand that the Roscoe basses ship with. Sold the bass and no longer need the custom string sets. D'Addario Nickel Sizes: .30/.45/.65/.85/.100/.125 <- I think this is correct!! I wrap all my single strings and put them in an air tight zip lock bag for storage with a silicone pack inside. $37.00 for Both sets SHIPPED to CONUS Lower 48 Only!
