Layer your guitar signal with the Hotone Harmony Pitch Shifter Pedal. When you stomp on the Harmony, it will generate a pitch-modulated signal which you can mix in with your dry guitar signal. This second signal can be set to harmonize with your fundamental tone for faux chords when it's in Pitch Shift Mode, or be a slightly detuned double for an expansive layered sound in Detune Mode. The degree of shift/detuning is determined by the large top knob. The front-panel knobs are used to mix the wet and dry signals for the desired output. Since the footswitch is true bypass, the Gate pedal will not color your tone when you take it out of the circuit.
