Keeley Noble Screamer Overdrive and Boost Pedal

Mix and match two instances each of two different analog drive circuits to create your uber-tone with the Keeley Noble Screamer overdrive and boost pedal.

Imagine the ability to combine the best and defining characteristics of different overdrive & boost pedals in order to create hybrid sounds no one has ever played through before. That is exactly what Keeley has engineered with the Noble Screamer.

It's a 4-in-1 pedal that gives you two very familiar drive circuits and two amp-like overdrive and distortion tones. It's almost like pedal-modeling, except these are 100% analog circuits, and you decide which tone-control or clipping-section you want to play through. Toggle between battle-tested, classic overdrive effects or innovate your sound using hybrid tones; let your ears be the judge.

Even with all of these features, the pedal remains a user-friendly three knob overdrive. The innovation in the Noble Screamer doesn't end there; the design features true-bypass or buffered, truly silent switching, on the fly. The Keeley Noble Screamer Overdrive and Boost is entirely manufactured at Keeley Electronics and is the first release in the aluminum enclosure.

Watch Justin experience multiple 100% analog overdrive circuits in our zZounds exclusive video demo:

Tone Control
Broad Spectrum Tone Control or Narrow Focus Filter Control: The Noble Screamer gives you two tone control circuits to choose from. When the Tone Switch is up and in the OD Position you will hear a 'Spectrum' type of tone control that has the ability to go from a flat EQ to an EQ that has a boost in the treble and bass response. If the Tone Switch is in the TS Position read more you have a Low Pass Filter that rolls off the high frequencies only.

Diode Clipping
Hard or Soft Clipping: The Noble Screamer gives you both styles of diode clipping. Diodes are used to create hard clipping distortions or smooth overdrive sounds. If the Clipping Switch is in the OD Position it features Hard Diode Clipping which is an edgier, more aggressive tone. When the Clipping Switch is in the TS Position that uses Soft Diode Clipping, like a tube amplifier softly overdriven.

Noble Screamer Has Both Buffered and True Bypass
The Keeley Noble Screamer features the Vitamin K Infused Buffer for noise free switching. Keeley have developed an amazing sounding buffer which not only makes your rig sound better, it gives you silent switching with no tone loss. No more pops and clicks to distract from your music. If you want to turn that feature off and go back to true bypass, simply press and hold down the foot switch for two seconds and the pedal will switch to True-Bypass (LED will flash twice). True Bypass is great for players that want the effect of plugging directly into their amp when the pedal is off. Alternatively, players that want a strong and clear signal even when the Noble Screamer is turned off, simply hold the stomp switch down for two seconds and the effect is back to Buffered Bypass (LED flashes three times). Enjoy truly silent switching and let your music be the only voice.

Made In The USA
Keeley design, engineer, and manufacture the Noble Screamer in Oklahoma City. Everything about the Noble Screamer is geared towards the professional musician and their quest for an inspiring tone when the performance demands it. From the inside of the pedal and its meticulously built circuit boards and metal construction audio jacks to the outside of the effect its fabricated aluminum enclosure; Keeley make guitar effect pedals to be finely crafted musical instruments.
