This would be a nice feature and seems simple to implement. In "output", it would be nice if there was a button you can turn on and off to set a default volume, since the volume you turn the amp off is saved till when you turn on it, and can't be lowered till you turn the amp on again. Unlike an analogue amp, where I can set the volume without the amp being on.
Every time I play it loud, I have to lower the volume to 0, then turn it off.
It would be nice if you can set the volume as a default value to whatever you want so when you turn it on, its always that volume, then you can raise or lower it.
