I bought my autoharp from a guy who was playing it in a rock band.
(tho I suppose you could argue that autoharps aren't any kind of traditional)
He said he was selling it because, even miked, it wasn't loud enough.
I found what he didn't say even more interesting: He didn't say anything about how hard it is to tune, or to tune the other instruments to it.
Of course tuning isn't relevant to bagpipes either, right?

Sorry, couldn't resist.
Blessings,
