Noble Screamer Overdrive and Boost

Keeley Electronics Noble Screamer Overdrive and Boost Effect Pedal

Imagine being able to combine your favorite parts of different overdrive & boost pedals in order to create hybrid sounds no one has ever played through before. That is exactly what we’ve engineered with the Noble Screamer. It’s a 4-in-1 pedal that gives you two very familiar drive circuits and two brand new amp-like distortion tones that no one has used before. 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. You can play through battle-tested, classic overdrive effects or innovate new music with hybrid tones, let your ears be the judge. Even with all of these features the pedal remains a simple and easy to use three knob overdrive. The innovation in the Noble Screamer doesn’t end there; our new 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 in our new aluminum enclosure.

  • Four Overdrive and Boost sounds – including two new, amp-like hybrid tones
  • Silent Buffered Bypass or True Bypass – hold down foot switch to change quickly
  • Professionally Engineered Tone – sounds developed in the field and in our tone lab

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 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 our Vitamin K Infused Buffer for noise free switching. We 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

We 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 newly fabricated aluminum enclosure; we make guitar effect pedals to be finely crafted musical instruments.

    This thing sounds great. Very well built, and looks cool too! Like having 4 drives in 1.

    There are just not enough words to describe how great this pedal is. I’ve played it daily since I got it and am still finding new tones in it. I love the OD/OD setting and the OD/TS setting the most but have yet to find a bad setting. And the new style enclosure is world class too! Can’t wait to see what the Keeley folk come up with next!!!

    Keeley makes me proud to be an Oklahoman. As a long time lover of the ODR-1 and having owned many variations I can confidently say this is the best and my favorite. The power it has, the way it cleans up, it does not sound like a pedal. It sounds so alive. I’m buying a second to have the eq side set on TS because that’s a whole new sound that is incredible. I’m overjoyed and so proud of this pedal. Keeley hit another grand slam.

    I absolutely love it! I tested it with a few Strats and a ’65 Deluxe Reverb amp. Took me maybe…….10 seconds to dial in my perfect tone (Volume at unity, Gain at “6”, Tone halfway up, and BOTH switches set to “OD”).
    But, I can add in the midrange hump of a TS just by flipping Tone switch to “TS”. Sometimes Fender amps, in a live context, need a lil’ boost in the mids.
    Pedal is low-to-no noise. Very tuneful.
    Another success from Robert Keeley and the RKFX team!!!

    Initial impression (after 2 days): fantastic! This pedal is intuitive and dials up great sounds — from slight break up to huge OD (fuzz-adjacent). It has amp-like response to volume changes. Option for buffered or non-buffered bypass — superb feature.

    I also have to give a shout out to Keeley service. Somehow, the migration to the new server left me locked out of my account. After a few days of frustration, I emailed Keeley. Within 30 minutes, I received a personal call — unfortunately I can’t recall the name of the supper friendly person who quickly resolved the issue. Two days later, I had my Noble Screamer. Two, actually — the second one is a gift for my son-in-law.

    Directly compared the noble screamer to my rehoused original nobles and they were so, so close. I feel like the noble screamer has the same feel as my odr and acts exactly the same rolling off the volume. The Ts side sounds like a ts and I honestly haven’t deep dove into the different features as I am just getting some amazing tones on the od side. I honestly had my doubts because of so many pedals that don’t come close…… this one is absolutely worth it!
