Daredevil Pedals Double Atomic Cock Fixed Wah and Boost w/ Footswitchable Sweep Settings What we have is a smooth sweeping wah with a single knob to set your pitch. A boost section has been added to give you more gain and power as needed. Balance these two features out with the Blend control, adjusting how much wah signal goes to output. Very cool for dialing in the cocked tone subtle enough to be left on all the time, or for just a bit of a frequency tweak. Full clockwise gives you the complete effect. The gain section is warm, loud, and gives a nice crunch to your amp's output. No need to try and hit a boost before hand, it's all there. Get the killer tones from the likes of Mick Ronson, Micheal Schenker, Slash, etc...
