Balls eliminate the need for tying the string at the bridge to facilitate easier attachment. String Set Gauging String sets are available in a wide range of gauges ranging from Super or Extra-light gauges, to Medium or Regular gauges, and up to Heavy gauge. If note-bending is the crucial consideration, then get light gauge strings. Rhythm players in rock groups and dance combos, who need a full, solid sound, often choose heavy gauge. Core Wire Wrapped steel strings are wound on a high carbon tinned steel core wire.
Core wire can either be round or hexagonal.
Round Core Wire Advocates of round core wire argue that the wrap is tighter and vibration is more even and true. The most common core shape is hexagonal although other shapes may be used. Stringmakers who use hex shaped core wire do so because the corners of the core wire dig into the outer wrap, resulting in a greatly improved mechanical bond. The end result is a longer lasting, more durable string. Shaped core wire can be ordered from the wire mill, but some stringmakers choose to shape it on their own equipment.
