I get no guitar through the headphones. What must I do to get the audio from my guitar to the headphones? I would like to use this as a line signal to another amp.
I do get audio out from my phone to the headphones when Bluetooth is connected. When Bluetooth is connected, whatever is playing on the phone will be heard through the headphones. So, I know the headphones AND the headphone jack both work.
Thank you for getting in touch, this is not something we have come across before, I would suggest having the amp looked at by an engineer, please contact your dealer to get this arranged.
