The MINI-CHORUS is the same thing as our standard chorus, but in a smaller, hand stamped box. It is the same SIZE as our small comprossors/juicers, 2.5" wide x 4.75" long x 1.5" tall not including swithes, jacks, etc. Same price as the normal Chorus, $225, as the box is a little cheaper but the extra labor to build the pedal into the small box is a lot more than the box savings.
