Seymour Duncan Killing Floor High Gain Boost – Very Good Condition

The Seymour Duncan Killing Floor High Gain Boost is a powerful, amp-like boost and overdrive pedal that adds clarity, punch, and harmonic richness to any rig. Whether you need a clean volume lift for solos or want to push your amp into smooth, musical overdrive, the Killing Floor delivers outstanding touch sensitivity and dynamic response.

With up to 34 dB of gain on tap, this pedal can function as a subtle tone enhancer, an always-on sweetener, or a high-impact boost to drive your amp harder for thick, expressive lead tones. The intuitive single-knob design makes dialing in the perfect level of boost fast and easy, while the 3-way voicing switch lets you tailor the high frequencies to match different guitars, pickups, and amps.

This unit is in very good condition and works perfectly. A great choice for players looking for a versatile boost that enhances tone without coloring it excessively.
