- RANGE Knob: Adjusts the range of the pitch shifting sound, from 1 to 2 octaves.
- WET Knob: Adjusts the volume of the wet (effected) signal.
- Mode Switch: Toggles between UP (Harmony/Pitch Shift up), DETUNE, and DOWN (Harmony/Pitch Shift down) modes.
- DRY knop: Adjusts the volume of the original (dry) signal.
- Indgangsstik: 1/4" mono audio jack for guitar input.
- Udgangsstik: 1/4" mono audio jack for output to amplifier eller andre pedaler.
- DC 9V strømstik: For DC 9V regulated AC adapter (plug polarity is positive on the barrel and negative in the center).

6. Betjeningsvejledning
The Harmonizer pedal offers three main effects modes: Harmony, Pitch Shift, and Detune. You can control these effects using the Mode Switch and the three control knobs.
6.1. Engaging and Bypassing the Effect
- Tryk på True BYPASS Footswitch (1) once to toggle between the original (bypassed) sound and the effected sound.
- When the effect is engaged, the LED-indikatorlys (2) will illuminate (green or red). When bypassed, the LED will be off.

6.2. Selecting Effect Modes
Brug Tilstandsvælger (5) to select one of the three available effect modes:
- OP: Engages Harmony or Pitch Shift upwards.
- DETUNE: Engages the Detune effect.
- NED: Engages Harmony or Pitch Shift downwards.

This image highlights the mode switch, indicating the three distinct effects: Harmony, Pitch Shift, and Detune.
6.3. Adjusting Effect Parameters
De RANGE (3), WET (4), og DRY (6) knobs allow you to fine-tune the effect:
- RANGE Knob: Controls the pitch interval for Harmony and Pitch Shift modes, from 1 to 2 octaves. In Detune mode, this knob adjusts the degree of detuning.
- WET Knob: Adjusts the volume of the processed (effected) signal. Turn clockwise for more effect.
- DRY knop: Adjusts the volume of your original, unprocessed guitar signal. Turn clockwise for more dry signal.
6.4. Normal Mode vs. Fixed Mode and Parameter Storage
The pedal supports two operational modes for parameter adjustment:
- Normal tilstand: Indikeret af en grøn LED. In this mode, you can freely adjust the RANGE, WET, and DRY knobs to change the effect parameters in real-time.
- Fast tilstand: Indikeret af en rød LED. In this mode, the pedal uses a previously stored set of parameters. The physical positions of the RANGE, WET, and DRY knobs will not affect the sound. This is useful for recalling specific settings instantly.
- To switch between Normal and Fixed modes, press the True BYPASS Footswitch (1) hurtigt to gange.
- To store the current parameters (knob settings) into Fixed Mode, press and hold the True BYPASS Footswitch (1) for an extended period until the LED flashes or changes to confirm storage.
