Founded on the spirit of continuous improvement and a passion for their vintage roots, DiMarzio's parts remain faithful to these same ideals, because they know that the performance of your pickups is only as good as the parts they're wired to. So they took to searching the industry for the most rugged, reliable, and greatest sounding electrical components to offer to their customers, including a range of parts that are specifically custom-built for DiMarzio. Since 1946, Switchcraft has been using military grade designs and virtually bulletproof quality materials to consistently produce the most natural and musical sounding selector switches available. Lesser switches suffer from a noticeable signal loss, and utilize rounded contact tops that infamously cause the switch to fall out of place, even after minimal use. Using a square contact, the Switchcraft design doubles the contact area for an unmatched reliability in any position. Includes a flush-mount flat knurled nut and a deep knurled nut, along with screw-on cream knob. This switch directly retrofits USA Gibson®, with a 15/32”-32 threaded bushing.
