Let's face it, the 1/4 inch Jack socket you're using in your guitar and your pedals was designed in the 19th Century for patching phone calls. The new Pure Tone jack makes those old crackly 1/4 inch jacks obsolete! The Pure Tone jack contains dual tension grounds and dual positive tips for optimal signal and lowest possible noise. Greater surface area at all contact points creates a more stable connection, locking the cable securely in place and carrying more signal; as a result, high and low frequencies are greatly improved creating a much more balanced sound while eliminating frequency spikes. Most importantly, the Pure Tone Jack eliminates the infamous “crackle” noise caused by pressure grounds. The Pure Tone jack tensioned design locks the cable securely in place and the increased metal mass carries more signal.
