3. Setup Instructions
Follow these steps to set up your AHAR-3 Harmonizer pedal:

4. Operating Instructions
The AHAR-3 Harmonizer pedal offers intuitive controls for shaping your sound:
- True Bypass Footswitch: Press this footswitch to toggle the effect on or off. When the effect is active, the LED indicator will light up.
- MODE Switch: This three-position toggle switch selects the harmonizer mode:
- UP: Shifts the pitch upwards.
- DETUNE: Provides a slight pitch variation for chorus-like effects, ranging from -25 to +25 cents.
- DOWN: Shifts the pitch downwards.
- DRY Knob: Adjusts the volume of your original, unprocessed guitar signal.
- WET Knob: Controls the volume of the harmonized (effected) signal.
- RANGE Knob: This large central knob selects the pitch shift interval. Depending on the selected mode (UP or DOWN), it allows you to choose intervals such as 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 9th, 10th, 11th, 12th, 1 OCT (one octave), and 2 OCT (two octaves). In DETUNE mode, this knob fine-tunes the detune amount.

- Ensure the power supply is stable and providing sufficient current (68 mA minimum).
- Test with different cables and a different amplifier if possible.
- Effect Not Changing:
