guitar cabinet, since a) the cabinet would be close-miced, and b) there
probably isn't a monitor aimed directly at the front of the guitar cabinet.
It would NOT be suitable at all for vocals, or when you're micing horns,
acoustic guitar, violin, etc.
It would also be complicated if you are using side-fills, as is
typical. Of course, it's also complicated by stupid things such as
whether or not the lead singer decides to put on a hat!
I mixed monitors for many many years. It's far more complicated than it
would appear at a casual glance. You get 8-10 on-stage monitor mixes,
running a total of about 100,000 watts (including sidefills), and
there's a lot going on.
It all depends on the circumstances. I never wrote that you could
blindly replace all your SM58s with omnis. I wrote that I've done
it in some cases, and with good results.
Also note that the miniature DPAs often used on violins, horns and
others (including singers) are omnis.
