I respect the views of Jed and Fortunato and would always use a regular and good sound man if I could afford one (and then find one). Unfortunately very few of us can and because of disastrous experiences with inexperienced soundpersons in the past I now prefer to do my own mixing. Generally it is not too difficult to find one or two friends with a "good ear" to stand in the room/hall/auditorium and help with the balance and mix. As long as no-one then "does their own thing" with individual levels subsequently, I find this works quite well.

As for concentrating on being a musician, I would far rather do the above than be trembling with anger and fear on stage looking into the uncomprehending eyes of the "soundman from hell"!

Best regards,
