Quick Guide
The Behringer HD300 is a high-quality distortion effects pedal designed for hard rock and heavy metal sounds. Note that the pedal does not have a dedicated on/off switch. It activates automatically as soon as an instrument cable is inserted into the IN connector. To preserve battery life, always remove the cable from the IN jack when the pedal is not in use.
Controls
The pedal features five main control knobs to shape your sound:
- LEVEL: Adjusts the overall output volume of the pedal.
- TONE: Allows you to shape the overall sound character.
- BOTTOM: Boosts or cuts the low-frequency range.
- DIST: Adjusts the intensity and amount of distortion.
- GAIN BOOST: Adjusts the gain for more extreme distortion sounds.
Additionally, the ON/BATT LED illuminates when the effect is active and also serves as a battery level indicator. The footswitch is used to activate or deactivate the effect.
