$55 · Boss CE-3 Chorus | Reverb pedal

takes a 9v battery, or you can use a wall adapter (basic adapter, the source sells them) taken from the Boss site.. The Rate knob begins our journey into the CE-3, and it controls the overall speed of the chorus effect, as you might expect. The Depth knob is up next, which adjusts the intensity or presence of the effect, from a slight, mild chorus effect to a shimmery, watery, liquid tone. Adjust these two to taste as you see fit, and exploring the wide range of sounds available will truly be music to your ears.
