Troubleshooting
First check that your shielded guitar cable, speaker cable, and power cable are
connected correctly. If possible, use a tester to check the cable or try using an
alternate cable or amp to verify your cable's condition.
1. The power supply cannot be switched on.
• Check that the power cable has been connected correctly.
• Try plugging it into a different socket and see if the same problem occurs.
2. The power supply can be switched on, but no sound is
heard.
• Check that the bass guitar has been connected correctly.
• Remove any external components connected to the effects loop and between
the bass guitar and the amplifier and check to see if any sound is heard.
• Use a different shielded cable and check to see if any sound is heard.
• Check to see if the volume on the bass guitar is set to "0".
• Use a different bass guitar and see if any sound is heard.
• Check to see if the volume on the amplifier is set to "0".
• Check to see if the headphones are connected.
3. Noise is heard.
• Check to see if anything in the immediate vicinity is resonating or banging
against the amplifier to produce the noise.
• Check to see if the plug cover on the shielded cable is loose.
• Make sure that the action (string height) of your bass guitar is set correctly.
• Use another bass guitar, effects or other external components, and cable to
see if the same noise is produced.
4. No sound when you connect a CD/MP3.
• Make sure that the volume of the CD/MP3 player is not turned to 0.
• Make sure that the cable is connected correctly.
• Try using another cable and see whether any sound is heard.
5. The CD/MP3 sounds wrong.
Does the cable you're using have a stereo plug? Could you be using a monaural
plug?
6. No sound is produced in the headphones.
• Check that the headphones are connected correctly.
• Connect another set of headphones and see if sound is produced.
