3. Bedienelemente
The JHS 3 Series Chorus features three primary knobs and one toggle switch for shaping your sound:
- Volumen: This knob controls the overall output level of the pedal. Adjust it to match the volume of your bypassed signal or to boost your sound when the effect is engaged.

- Rate: The Rate knob adjusts the speed of the chorus or vibrato modulation. Turning it clockwise increases the speed, creating faster, more intense wobbles. Counter-clockwise movement slows the modulation for a more subtle, swirling effect.

- Tiefe: This knob controls the intensity or depth of the modulation. A lower setting (counter-clockwise) provides a gentle, less pronounced chorus. Increasing the depth (clockwise) results in a more pronounced, seasick-like modulation.

- Vibe Toggle: This two-position toggle switch alters the character of the effect. When engaged (up position), the Vibe toggle removes the dry signal, transforming the chorus into a true pitch vibrato sound. In the down position, the pedal operates as a standard chorus effect, blending the modulated signal with your dry signal.
