Hi, so there's a high pitch whining sound coming from my amp both with and without the guitar plugged in, I believe it started around when I first tried the in-built bluetooth feature and think this is the reason for my troubles. The whine starts at 10% on the master volume knob and progressively gets louder as you crank it up
When I tick the 'share audio' button on my phone, the whining stops, and is replaced by a very managable amount of noise.
I've already done a factory reset to try and disable bluetooth but the whine is unchanged and bluetooth is still on. I've also tried disabling all bluetooth devices nearby, shutting off my pc, taking away my phones and switching wall sockets (although I haven't tried outside my room yet).
Is there any way to disable bluetooth on the CODE 50? Or maybe I can take it apart and remove the transmitter myself.
Thank you for your comments, we would recommend the amp is looked at by an engineers to check it over, your amp should be able to unpair from any device, you will need to make sure you forget the connection not just unpair.
