The Electro Harmonix Analogizer Tone Shaper thaws out digitally processed guitar and gives you the sound and feel of an analog delay without the long delay times. The circuit is a clever combination of overdrive and a very short analog delay which come together to offer a warm rich tone when engaged similar to vintage pedals that used bucket brigade chips. If you want an old-school warmer sound the Analogizer instantly lets you achieve exactly that. Go old-school Fatten your sound. The Electro Harmonix Analogizer Tone Shaper is the antidote to harsh and lifeless sounding digital pedals. The Analogizer features four controls: Gain Spread Blend and Volume. The Gain control allows a user to boost their input gain up to +26dB which means this versatile pedal can also act as a surprisingly effective rudimentary booster. Spread controls the delay time of the Analogizer from 3.5 mS to 65 mS (this helps give the warmer darker sound rather than acting as a literal delay). Adjustments in the lower-half of its range provide tonal variations to the effect. Adjustment in the upper-half can be used to thicken up a players sound. Blend enables a guitarist to mix their direct and affected signals from 100 dry to 100 wet. Volume controls the pedals output level.
