SOME TIPS
* Before you test the pedal or before playing, make sure the guitar is fully connected with the pedal;
* More importantly, you need to make sure it meets the working current requirement of each single pedal.
* In order to make JOYO pedals work properly, avoiding unexpected noise caused by power supply, we recommend that you purchase a JOYO original power adapter, or choose other reliable brands.
