I will preface this by saying my current project is just my guitar, drums and vocals. I wasn't sure how the 50 would hold up under live drums in a rather large rehearsal space. Turns out I didn't have to worry at all. I didn't need to turn it past the 4th line on the master, which is actually 3 because the first line is 0 with no sound. Controlled the volume from the app on my phone and I actually backed the master down a little too for less aggressive songs. No clean settings, all overdriven early white stripes tone settings I created. Drummer isn't super loud but definitely not quiet either. If you are competing with other guitarists using 100 watt Marshall heads and stacks, its obviously not a great choice but for the vast majority of people, the 50 is going to be plenty loud for most situations. Just thought Id share.
