Seymour Duncan’s Killing Floor High Gain Boost electric guitar effects pedal is a powerful tool for wringing the most gain, responsiveness, and tone from your amplifier, while remaining one of the easiest pedals to dial in on your pedalboard. The gain knob adds in up to 34dB of overdriven boost that works for gain matching guitars, boosting for solos, or tightening up distorted amp tones. The 3-way toggle switch boosts or cuts carefully selected high frequencies for precise tonal shaping. Many players have found the Killing Floor to be an always-on pedal that puts their tone over the top.
