What does this mod do?  

This turns your Dunlop DVP5 Volume (X)8 pedal into a functional toe-switch and expression pedal, perfect for use with your Neural DSP Quad Cortex.  

Once installed and set up properly, this can be used like like a full sized expression pedal with toe switch, but in a convenient mini-size perfect for your small pedalboard!   Modifying the pedal in this way removes the ability to use it as a stand-alone volume pedal.  For the Quad Cortex, two jacks are required.  TRS Cables are required for use with either modification. 

This modification is performed at the Tesi Switch shop in Nashville, TN.

The existing circuit board is removed from the pedal to accommodate the toe switch and we include it in the box in case you decide to return the pedal to stock functionality.
