A rare Guyatone pedal that enhances virtually any kind of distortion with, because with the “Color” control, you can vary the harmonics from even to odd. The “Exciter” adds a brilliance to the sound, similar to the Aphex Aural Exciter, so it can even be used for vocals.

With the “Color” turned to the left, around 9 o’clock, you get even harmonics, close sounding towards a tube amp’s distortion. Placed after the distortion, you could step on it to boost your solo levels. This was a versatile, superb and underrated effect.

This unit has quite  a few scratches. This unit does not come with a bag or case and does not include a power supply. This unit has been tested and is in working order.
