"Loud enough"
This is -always- a trick question.
Loud enough for whom?
In what circumstances?
With what other players?
I had a standing gig every Friday for 3 years or so, to a 150 or so seat venue, with a 5 piece band of bass, guit, piano, drums, and sax.
It was always enough for that band, in that room, with those players. They were all older session guys like me, who had a great sense for listening to each other, and, didn't want to play terribly loud.
In the three piece blues band I was working in at the same time; no way it was enough, but, adding the Mesa 115 under it worked fine.
You've played it, you have a feel for what it'll do.
It's not Terribly Loud;
but,
adding another speaker, or, using it with a different, bigger 410 or something works well; and I gigged mine that way for many years.
