Pitbull Gold Series bass guitar strings are made of hexagonal American steel core wire and nickel alloy windings wound on it. Because nickel is an alloy, it cannot be stripped off the wire, like nickel-plated windings. This has a positive effect on the tarnishing process in the wires. In addition, nickel alloy windings have a unique, dynamic sound character. Thanks to the “Pitbull Bite” feature, the tuning consistency is at the highest level. Again, thanks to this feature, the strings are easily attached to the tuner of your bass guitar. It is indispensable for recording and concert performances.
