It's not only Bluetooth. My Amplifi 150 continuously cuts out on any music source, guitar, bluetooth, usb. It cuts out every few seconds randomly and then comes back on. Very annoying and extremely disappointing considering how this product was touted as such a breakthrough. I've opened a service ticket but am not hearing back from line six even after the promised 3 business days. Nice customer service guys. Not a happy customer! Please make me happy again and not regret this, and any future, line 6 purchases
