The JG100 Jack Guard will perfectly seal any OE inch input and output jack and provide powerful antistatic protection that repels smoke, dirt, and dust particles away from the installed jack. A newly created material called Plasiccant, enables the Jack Guard JG100 to quickly absorb ambient moisture from your instruments and equipment's interior cavities and provides continuous moisture control for up to one year. The JG100 Jack Guard was designed for all OE inch, input/output jacks. Guitars, amps, effect pedals, keyboards, soundboards, and home audio systems are exactly what the Jack Guard products are designed to protect.
