The Bad Stain Gold Canyon Echo effect pedal is a perfect addition to anyone’s arsenal. The digital design circuitry gives the Gold Canyon a sound and tone that is capable of competing with other much more expensive Echo effect pedals. The Gold Canyon features a 12 gauge shotgun shell “Rate” knob in the center of the pedal that adjusts the speed of the effect. Above the large knob are three small knobs that are used to adjust various settings. The “Level” knob adjusts the volume. The “Repeat” knob adjusts the actual echo effect. The “Tone” knob adjusts the tone and sound of the echo effect. The fact that the Gold Canyon has four knobs makes the pedal capable of producing a wide array of unique echo sounds. The Gold Canyon 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 Gold Canyon Pedal, you should probably buy a different pedal.
