Quick guide from the manual
The Chord OD-50 is an overdrive and distortion pedal for electric guitars. To get started, install the included 9V battery in the underside compartment or use an external 9V DC power adapter. Always unplug the guitar input jack when the pedal is not in use to preserve battery life.

- 1. Optional 9V DC jack power input: For external power supply.
- 2. Effect on/off indicator: Shows if the effect is active.
- 3. Gain: Adjusts the amount of drive or distortion.
- 4. 6.3mm jack output: Connects to your amplifier.

Operation
The OD-50 emulates an over-driven amplifier. To shape your sound:
- Increase Gain: For more distortion. If the volume increases too much, back off the Level control.
