The Analogizer Pedal from Electro-Harmonix features four control knobs, Gain, Spread, Blend, and Volume for preamplifier, equalizer, and tone shaping control. This pedal is used for warming up the harshness of your digitally processed guitar, or for thickening up an already warm sound. The Analogizer can be used in combination with other effect devices. The unit has a footswitch which toggles between effect and true bypass modes, and has up to 26 dB of adjustable gain.
