This item is in good working condition. It looks like someone used a black marker on the edges of the face. There are some case scratches mostly on the foot pedal and but there are some also on the rack. The foot pedal doesn’t need a battery to work. It comes with a 12 foot cable for the foot pedal. It comes with its original power supply ECB007. 9 volt battery not included.
The remote footswitch input acts as a all off switch when used with a TS footswitch (not included). This is not explained in the manual, but I was able to confirm this function with a Dunlop tech. Also the two LEDs on the foot controller is a battery indicator on/off light. You can turn the battery on and off by pushing in the red button on the side of the foot controller. If there is no battery, it is best to have the red switch off as it changes the wah sound.
The Dunlop Custom Shop Rack Wah gives more control over your wah tone than any wah pedal in the world. The 6-position switch lets you select the sweep frequency range, and the variable Q control determines the wah’s bandpass shape. The adjustable boost (up to +10dB) makes the Rack Wah even more flexible. You can connect up to six pedals and place them anywhere onstage. The two outputs give you an astounding amount of routing options for unprecedented versatility.
