Speaker Cranker

The Speaker Cranker by EarthQuaker Devices is a discrete, all-analog distortion enhancement device designed to provide extra grit and a slight boost without significantly altering the original tone. It is not a booster but rather an overdrive, intended to emulate the effect of adding an extra preamp tube to an amplifier for increased overdrive.
