This new panel-mount jack boasts full contact for optimal signal and lowest possible noise. The patented jack design creates a more stable connection, locking the cable securely in place and carrying more signal. The Pure Tone Jack eliminates the infamous “crackle” noise caused by pressure grounds. This long-threaded jack can be used in both mono and stereo applications. This panel mount jack joins the popular Pure Tone lineup of mono and stereo ¼” jacks.
