Thank you for viewing. This is a used MXR ROCKMAN X100 and the dedicated footswitch M199. The footswitch is used for mode switching. They are not sold separately, only as a set. This is a Moridaira authorized import, so repairs are also reliable. It was only used once and is in quite clean condition, but since it is used, please refrain from purchasing if you are sensitive to such things. The original box and other items shown in the photos are included.
