I just bought my first Marshall head(2266 vintage modern) and am now looking for a cab but only need a 2x12 cab and I think I'm gonna get a vintage avatar. Now I have a few questions

- how do cleans sound with greenbackS with a marshall 2266( how much headroom)?
- can I later get another 2x12 and daisy chain it so I have 2 2x12( how would this sound?
- would a 2x12 greenback cab with a 50 watt head be loud enough for an auditorium sized gig?
- if I get a second 2x12 what kind of speakers should I get to go with my already greenback cab?

Thanks for anyone who actually reads this and gives some answers
