This mod unlocks the true potential of the Zoom Multistomp series pedals, by making its features more easily accessible. Scroll left and right, use preset mode and even tap-in tempo using the footswitches of the Auxiliary pedal. The Auxilary pedal eliminates the need to bend and press a small knob or a button around the side of the footswitch to get to features you're looking for. This is a complete bundled package of a brand new MS-100BT, Auxiliary pedal and 2 1-foot TRS right angle cables. The mod requires the battery option to be permanently removed. Two jacks are installed, labelled 1 and 2 that correspond to the Auxiliary Switch.
