Pure Tone Technologies is a guitar hardware company based in New Jersey that manufactures multi-contact 1/4" output jacks for electric guitars and basses. The company was founded by Dave Linsk, lead guitarist of the thrash metal band Overkill, after he grew frustrated with the reliability problems of traditional jack designs that had changed little in roughly a century. Its products are distributed by AP International Music Supply, alongside other guitar-parts brands like Floyd Rose and Babicz.

The core product is the patented Pure Tone multi-contact output jack (U.S. Patent 9,680,264), which uses dual tension grounds and dual positive tips to roughly double the surface area at each point of contact. The design is marketed as a drop-in upgrade that reduces noise and signal dropouts while tightening the mechanical grip on a plug. The lineup includes mono and stereo versions, barrel-style jacks, PCB-mount variants, and finishes in nickel, black nickel, and gold plating, along with HiFi 1/4" audio plugs and replacement hex nuts.

Pure Tone has 2 products cataloged on Equipboard, including Steel-string Acoustic Guitars and Miscellaneous Guitar Parts.
