The Pure Tone jack socket provides dual tension ground (earth) connections and dual positive tips for optimal signal and lowest possible noise. 100% greater surface area at all contact points creates a more stable connection; as a result, high and low frequencies are greatly improved creating a much more balanced sound while eliminating frequency spikes. No more noise crackle caused by pressure grounds!

Comes complete with nut and washer and mates with a standard 1/4" phone plug, mounting in a single .469 inch diameter hole.
