I bet it's the same issue as above, IIC++ and other USA amp models mute the output. Petrucci Rhythm preset uses one of those amps.BUT when I select a factory patch (Petrucci Rhythm) again...the AX8 is muted .
Still Playing with it...Still loving Q10 sound
I had this exact same problem myself. Once you switch to the 2C++ it just cuts all output signal, but still registers as if you are getting something from the guitar on the unit, but nothing makes it to the interface. Also the sound doesn't return when you switch back to the previous working scene or preset. This is all I've noticed so far.Is Amp X/Y still an issue? I'm having an issue where setting Amp Y to USA IIC++ leaves the AX8 silent - have to power cycle it to get things back to normal.
Update sounds awesome though - great stuff!
