My marshall Code 25 suddenly muted randomly


Hi Marshall Support, 

After buying Marshall Code 25 yesterday, I feel something is wrong with it. My Marshall Code 25 suddenly muted  randomly, even sometime in the beginning I try to power on.  I already updated the latest firmware, but it still happen. 

What can I do with this situation?

Were you connected with the bluetooth app?

Sometimes my app randomly changes patches or even settings such as the gain will suddenly just jump to zero (muting the amp).

No, I didn't. - Achmad Bahtiarsyah 26 Mar 2022 at 11:23 AM


I'm having the same problem.  My amp just randomly goes on mute. Only when I don't have headphones plugged in. Tried updating the firmware.

Can you help?
