The pedal is quite simple to use, once you expirement with it for a short while. The Pedal has an E. Level (Wet/Dry signal), Rate (Vibrato effect), Depth (Level of Chorus), and a Filter. The unique thing about this chorus, over the Boss Super Chorus, is its Filter. Its a two-stage filter, so basicly you can filter your Hi's and Lo's (Bass & Treble). The filter is really the reason i chose this pedal, because you can achieve alot more sounds w/ it. This pedal can make a large variaty of sounds. I can tweak this pedal to perfection at times. Currently I'm playing a MIM Stratocaster along w/ a Peavey Classic 30, and the pedal can achieve the sound of my favorite artists like RHCP, Janes Addiction, and Jimi Hendrix. This is my personal favorite Chorus pedal, and I've owned a EHX small clone, and I think its a great pedal as well, but I prefer this over it, simply because you can tweak this Boss to sound exactly how you like.
