If you're not hearing any effects, here are a few steps you can try: 1.Turn the "Volume" knob and "Effects" knob to the maximum. 2.Check the cable connections by unplugging and reconnecting the three cables on the right side. 3.If you have an external speaker, try connecting it to see if the effects work with the speaker.

Firstly, check whether the indicator light turns on when you charge the guitar. If the light does not turn on, try using a different charging cable or adapter and charge the guitar for an additional 6-7 hours to see if the issue persists. Secondly, ensure all cables are securely connected to the preamp. Unplug and replug the cables, and make sure they are connected correctly. If these steps do not resolve the issue, please reach out to our customer service team for further assistance.

To measure the action, first tune your guitar to standard tuning. Our standard action measurements for the guitar are as follows: the 6th string at the 12th fret and the 1st string at the 12th fret should be 3mm, with a tolerance of plus or minus 0.1mm. If the action is too high, consider adjusting it by carefully sanding the saddle.
