The Guitar Effect Switcher is an open sourced, intuitive way to build your own effect switcher, rather than paying top dollar for similarly equipped pre-built products. You control which effect preset is in use by hitting one of the affixed buttons. This system can be configured to have different combinations of effects enabled based on whatever setting the user desires, all through an easy-to-use app. The device can store and recall the current set of configurations for the affixed buttons, enabling a configuration to be set during practice or rehearsal, and not having to worry about setting it up again later.
