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. The full mod includes drilling 2 holes into the case and adding two jacks to connect your Auxiliary pedal. The mod requires the battery option to be permanently removed. You'll need to send in your Zoom pedal to be modded and we do it for you. The mod will be done within 1-2 weeks once it has been received we will send your pedal back along with the Auxiliary pedal.
