Creation Audio Labs MK.4.23

The Creation Audio Labs MK.4.23 is a boost pedal. You can see the Creation Audio Labs MK.4.23 in the picture which I included on the left. This is a photo of one of Brad's pedalboards when he was still with Third Day. You can have a better look at this pedalboard here. The MK.4.23 is the third pedal from the left, bottom row.

You can have a closer look at this pedal here. On this image you can clearly see all of the pedal's knobs and controls.
