The Bare Knuckle Pickups True Grit Neck Humbucker is hand wound in the UK, features Alnico V magnets and is mainly aimed at hot blues, hard rock, grunge, stoner, punk and old-school metal tones. From their Boot Camp range, the True Grit pickups are in the medium output range and produce a fat, rich tone. The Bare Knuckle Boot Camp is a stripped back, no-nonsense pickup range aimed at guitar players who just want to cut to the chase and have great tone. The 50 mm pole spacing is the standard for neck humbuckers (including most guitars with tremolos), a larger pole spacing is only needed on guitars with wide nuts (and a tremolo).
