I just bought a new classic stingray and I really like the strings that came with it, but the string package was not in the case. Does anyone know which strings are shipped with these basses? There's no colored felt or anything, and they seem like medium gauge like maybe 40 - 100. I like the really low tension and the way they sound when slapping and popping. They're most likely some type of Slinky. Not sure if they're nickel or stainless steel.
