• Improper Fit in Guitar Jack: Due to variations in guitar jack plate angles, the amplifier may not fit perfectly in all guitars. Ensure a secure connection before use.
• No Sound: Check if the amplifier is powered on and fully charged. Ensure headphones are properly connected to the 'PHONES' jack and the guitar is securely plugged into the amplifier. Verify all volume controls (on the amp and guitar) are turned up.
