The Killing Floor high gain boost pedal—one of Duncan’s latest offerings—delivers up to 34dB of boost that will push any amp into overdrive. But there’s more than a staggering amount of boost at play here. The pedal also sweetens the tone of your rig, providing natural, amp-like dynamics and responsiveness while enhancing the most musical frequencies and harmonics.

In addition to a single chicken head knob for dialing in the desired amount of gain, the pedal offers a three-way mini toggle for boosting treble at 10kHz (to add “air” and more upper-end chime), cutting upper mids at 4.8kHz (to tame harsh single coil overtones), or keeping the tone absolutely flat.

The Killing Floor significantly improves a guitar’s tone, which will inspire many players to keep it on continuously, but it’s also great for dazzling solo tones that cut through a mix and sound rich and full.
