The Pure Tone Mono Shunt Jack delivers all of the proven performance benefits of the original Pure Tone 1/4" mono jack, now with the added versatility of an integrated shunt connection. Built around Pure Tone’s patented multi-contact design, it provides a tighter, more dependable connection with greater signal retention, lower noise, and improved long-term reliability.

Constructed from high-quality beryllium copper, the contact points offer superior conductivity, spring tension, and durability compared to traditional jack materials, ensuring consistent performance over time.

The added shunt feature makes it especially useful across a wide range of pedal, amp, and guitar applications. As an input jack, it grounds the input signal when no cable is inserted to help reduce unwanted amp noise. As a speaker jack, it can ground the output when no speaker is connected, offering added protection for your amplifier. In guitar wiring, it is an ideal replacement jack for custom mods that demand reliable, clean signal handling.

With dual-contact points on both the tip and sleeve, the Pure Tone Mono Shunt Jack maintains a stronger connection than standard jacks while expanding what your design can do.

3/8" hex nut (1) and washer (1) included.
