Designed to strike the right balance between protection and functionality, StompShield is a simple, yet effective solution that keeps knob settings on electronic devices such as effect pedals, amplifiers and alike from getting changed accidentally, while leaving unaltered the way they’re [settings] normally adjusted and monitored. StompShield is very easy to install and de-install. It is made of aircraft-grade aluminum to withstand years of abuse and features a non-obtrusive design that won’t conflict with the device aesthetics on which it is retrofitted.
