The Bad Stain Copper Creek chorus pedal features an analog design that is simple to use. The pedal only has two knobs, but is capable of producing a bright and warm chorus tone that shimmers with vibrance. The “Speed” knob adjusts the rate of the chorus effect, and the “Width” knob adjusts the depth of the effect in the mix. The Copper Creek is compatible with any 9 volt DC power supply (Not Included). However, we recommend using a Bad Stain 9 volt power supply because we make more money that way. If you’re not 100% satisfied with the BSNW Copper Creek Pedal, you should probably buy a different pedal.
