Things to check first

  • Check leads (Jack to Jack) These can be tested by the customer touching the end of the lead with their thumb and hearing a sound in the amp.
  • Is the mute button on?
  • Check the guitar! Is the guitar battery working if applicable?
  • Is the pedal power supply working?
  • Bypass the pedals/pedalboard to test the amp direct from the guitar.


Start from the beginning

  • Ensure all dials are set to zero and power is on.
  • Slowly turn up all dials to 1/4 way then play the guitar.
  • Turn off overdrive and go ‘clean’.
  • Turn dials to half way and play the instrument.
  • Try to play music through the amp from a phone (3.5mm jack to ¼ jack or 3.5mm jack to 3.5mm jack lead).
  • If there is a ‘rasping’ sound, the speaker cone is broken.
