I am just getting into mics and being amplified - ie I do know not much at all about it.
This week I played in a studio with a drummer friend who supplied an sm 57 mic which seemed very manageable. I like it that the horn has to be close to it for it to pick up the sound.
Occasionally I play along with a Samba band who are very loud and if I am not amplified then I won't be audible (except for when I drift into a break)
I suppose along with mics goes the question of mixers and amps if anyone has any views on those too.
