How to use: Connect your guitar to the input of the pedal and the output to your amplifier or audio interface. Since it doesn't have a power supply, you'll need to use an appropriate external power source. Just make sure the voltage of the power source matches the pedal's requirements. Attention: Always double - check the power connection to avoid any damage to the pedal. When you're done using it, turn it off properly. Maintenance tips: Keep the pedal clean and dry. You can use a soft cloth to wipe it gently. Don't expose it to extreme temperatures or humidity. Also, be careful when transporting it to prevent any physical damage.
