Rehearsal: Having trouble with the amp?

Things to check first:

  1. Ensure all dials are set to zero and power is on. 

  2. Bypass your pedalboard and connect your guitar directly to the amp.

  3. Make sure the distortion channel is off and the amp set to ‘clean’. Check this on the external footswitch, too (when applicable).

  4. On a bass amp, make sure that the Mute button is disengaged, and the EQ and Line Mix knobs are all set to the middle.

  5. Turn up the (Input) Gain and the (Output) Volume/Master knobs halfway through. You should now have sound.

Is the amp crackling when turning the knobs up or down? 

This may just be some dust buildup. Hit us up on live chat at so we can report this to our site tech, who’ll be able to clean up the dials when on site.

Is the speaker making a rattling or feedback noise? 

Try a different guitar cable or check it’s properly attached to both your guitar and amp. Do the same with the speaker cable at the amp and cabinet’s back (when applicable). Make sure that the Input Gain and Master output knobs are set to reasonable levels. 

Is the amp still silent? 

  • Check that the mute button is off.

  • Make sure that both the head and cabinet are properly connected via a speaker cable - it looks chunkier than a standard jack

  • If the power light is on, check that the speaker cable is plugged in correctly at the back of the amp and the cabinet. Only the speaker cable should be plugged into the ‘Speaker/Loudspeakers’ output ports on the amp.

  • If you checked all troubleshooting above and still have no sound when using your pedalboard, ensure that all your pedals are plugged and powered correctly.
