Imagine being able to combine your favorite elements of different overdrive and boost pedals to create hybrid sounds that no one has ever played before. That's exactly what we've done with the Noble Screamer. It's a 4-in-1 pedal that gives you two very familiar drive circuits and two new amp-style distortion sounds that no one has ever used before. The Keeley Noble Screamer Overdrive and Boost is made entirely at Keeley Electronics and is the first in our new aluminum case. Four overdrive and boost sounds - including two new hybrid sounds similar to those found on Silent Buffered Bypass or True Bypass - hold down the footswitch for quick changes. Professionally designed tones - sounds developed in the field and in our tone lab.
