I'm interested in getting a small combo for home practice so I don't have to set up my rig every time I want to play. The kicker is I would like it to have an external speaker jack that way I have the option to use it in a pinch in case my head goes down for some reason. Normally my band doesn't use PA other than for vocals so I never go into it. I know a combo into my 410 wouldn't be very loud but any sound has to be better than no sound right?
