Supercardioid dynamic vocal microphone on stage. A test on acoustic instrument, as it did a lot out in front of my classical guitar making a sound rather round, with a very soft tone while not made for that.

OVERALL OPINION

A good mid-range microphone (range equivalent to the SM58). If the doc gives a peak in the upper midrange and treble, it has low after suffocating me. Still the tone is very soft, round and deep. Many harmonics, but the effect of poximité too pronounced for my taste, popping and hissing at once very active. Indeed I am baritone / bass and my song quickly becomes very rough and incomprehensible words as soon as I arrive at the bottom of my range. A cut down will be necessary. Lacks a bit of momentum. Try to be more acute for the range: tenor and female voices for which he must have made a very good and again a very nice stamp.
He does not like me but adapted is a very good microphone for better quality / price ratio than the SM58. However, some slight finish: plastic part at the connection, switch very fragile.
I do not sell at the moment (it can be useful!) But I intend to buy another one soon.
I recommend it to female voices or high tessitura.
