A completely pre-drilled New Sensor 1590NS-DNP enclosure for a three knob pedal. Includes bottom plate. DC power jack, SKU: 0611C, is an exact fit for the DC Jack cutout on the enclosure. DC power jack sold separately.
Note: The holes for the input and output jacks are drilled to accommodate PC-mount jacks. They Will accommodate open-frame jacks if you file a notch in the lip of the cover. It took me about a moinute as shown in the detail pic. If you are willing to do a little tooling, the price is right.
