Keeley Electronics Noble Screamer 4-in-1 Overdrive Effects Pedal

The Keeley Noble Screamer is a versatile 4-in-1 overdrive pedal that blends the best characteristics of iconic drive circuits with brand-new amp-like tones. Imagine combining the punch and warmth of classic overdrives with modern analog innovation – that’s exactly what the Noble Screamer delivers. With two familiar circuits and two newly engineered voices, this pedal goes far beyond tradition, offering you a unique palette of analog-driven sounds.

Unlike digital “modeling,” the Noble Screamer uses 100% analog circuitry to authentically capture tone. You choose your flavor with switchable tone control and diode clipping options, unlocking a huge range of textures from smooth boosts to aggressive, amp-like distortion.

Classic Meets Modern Overdrive

The Noble Screamer gives you two tone circuits to explore: a broad-spectrum control that boosts treble and bass for added punch, or a low-pass filter that smooths out highs for classic overdrive warmth. Pair that with the choice of hard diode clipping for raw aggression or soft clipping for creamy amp-like breakup, and you’ve got four distinct overdrive voices in a single pedal.

Buffered or True Bypass – Your Choice

Keeley’s Vitamin K Infused Buffer ensures noise-free performance, stronger signal integrity, and completely silent switching. Want the purity of true bypass? Hold the footswitch for two seconds and instantly toggle between buffered and true bypass modes.

Handcrafted in the USA

Every Noble Screamer is designed, engineered, and manufactured in Oklahoma City. From the meticulously assembled circuit boards to the rugged aluminum enclosure, this pedal is built as a professional-grade musical instrument, not just a stompbox.
