The Defcon 4 is a combination boost and EQ pedal designed in close collaboration with Ryan Adams, offering four distinct stages of tone control starting with the Defcon 1 switch, which engages a 10db MOSFET boost. Atop that boost, you get three bands of EQ with individual toggle switches and rotary knobs to adjust the volume of each section.

If you're playing a Les Paul or something else with humbuckers, you can use the Defcon 4 to cut the low-end a bit to give your tone a little separation from the bass and drums.
