Scarlett Mousse

I'm kinda stupid. I could have gotten a Sapphire Pro 24 rather than a Scarlett 18i20. At least I think so.
But the Scarlett works and works great so maybe I shouldn't complain.

Pomplamoose does a great post with some actual numbers (which you know I appreciate) on touring and expenses.

Being in an indie band is running a never-ending, rewarding, scary, low-margin small business. 

This statement is, however, technically not factual. The margins are, indeed, quite high. It's just that the revenue itself isn't terribly high. One of the great ironies is that small businesses have to run much higher profit margins than big businesses just to stay afloat.
Other notes. The quote of $8794/week for 6 musicians and crew seems a bit high. I'm presuming that includes the $20/day per diem (which is low for per diem, in the 90's I was getting $40 per diem and that was low then.) But that makes an average weekly salary (including per diem) of about $210/day for a 7-day week. That might be a tad high for such a low-budget tour but it means they were paying okay (for a low-budget tour). But I might be wrong and the per diems came outside of that $8794/wk. It's not like they published a one-line for crying out loud.
In any case, two hundred bucks a day is okay for this kind of work.
