1) CODE 50 occasionally locks up when changing speaker cabinets (no sound). Must reboot.
2) sound gets progressively "muddy" when tweaking controls. Must reboot to get the sound back.
3) Cannot update: CODE connects to PC, but app generates error saying it cannot get information from the CODE.
Thank you for your message.
The update fixes the locking of the amp.
All you need to do is connect your amp to a PC via a mini usb and use the link below.
