Pitbull 30 Series bass strings are specially produced for short scale, that is, short neck bass guitars. Long Scale, that is, not suitable for long neck basses. It consists of hexagonal high carbon alloy American steel core wire and nickel alloy windings wound on it. Because nickel is an alloy, it cannot be stripped off the string, like nickel-plated windings. This has a positive effect on the tarnishing process in the strings. In addition, nickel alloy windings have a unique, dynamic sound character. Tuning stability is top notch.
