It is best to sell or trade in your Amplifi product while you can.  There is no immediate tech support. More importantly, lack of immediate parts availability when (and it will happen) your amp or pedal stops working. Sending to an authorized repair service out of warranty will cost you a lot of money and a lot of time for something that will fail again.  Sending it in under warranty is resolved by replacing a PCB board that is not in stock and that takes a lot of time.  As of this writing, up to two months to wait for your unit to return from warranty repair.  Ordering parts out of warranty from a local service center results in price gouging and delays.  A good concept that was poorly designed and supported.   I have owned the Amplifi 150, FX100, my friend has an Amplifi 150, and they all stopped working due to the main PCB, or the power supply.
