Infinity pickups are a line of magnetic transducers produced by Ibanez and installed in several Ibanez guitar models. They were designed as a cheaper alternative for the DiMarzio IBZ/USA and are used in lower end models (including the GIO line) which are made outside Japan.
The first Infinity pickups were introduced in 1994. A second generation was rolled out in 2005.
Infinity pickups were discontinued in most (if not all) models in 2015. They were most often replaced by the new Quantum pickups.
Neck humbucker introduced in 2005, replaced the Powersound pickups for the RG3xx and RG1xx models. Usually combined with Infinity 4 in bridge position and Infinity Single 3 in mid. It has a 1-15/16" pole spacing.
