It works okay. The pedal comes equipped with a slider where you have to chose if you're playing low, mid og high. The sound is okay, as long as you play within the register that you've selected, but it gets very glitchy as soon as you play anything else. It's pretty good to test if this is the effect for you, but if you like it, you will probably have to upgrade to more expensive gear. Like all Behringer pedals the casing is cheap plastic.
