This is a concept design for a multi-stomp guitar FX pedal. The whole idea is to create an enclosure large enough to fit in six FX circuits, six being the most basic yet complete set-up to an FX chain.
Compressor, Dirt, Dirt 2, Modulation 1, Modulation 2, Delay, Reverb. Of course this can be customized to one's liking with any other FX placed in whatever order and fashion.
