I have a strange thing happen when using my Fender Mustang Micro headphone amp with my Angelus SE. Although the amp works fine with a solid body, with the acoustic after about three songs the guitar shuts off. It’s not the amp because I still hear the backing track. If I “mute” the guitar as if I’m tuning and turn the volume back on, it comes through the amp once again—and then shuts off again after a few songs. I have no problem with the SE using a wireless transmitter so I’m wondering if it has something to do with the amp being a Bluetooth device as well.
