The Artec Tone Booster pedal is a simple two band equaliser boost. The pedal can boost or attenuate (by setting low) both bass and treble frequencies to sculpt the tone of your instrument.
This can be a great addition to either the front end of your amp, to shape the distortion characteristics of your amp, or in the effects loop, to provide some additional post-distortion tone shaping.
It has two 1/4 inch jacks on the side - one for the input, one for the output. It runs off 9v DC regulated supply and does not have an internal battery.
