I've used this mic to record acoustic guitars. I can only say that for it's price it really shines! Placed for recording both at 12th fret and at the bottom of the lower bout, the mic delivers a very clear and truthful acoustic sound rendition. I've been even able to record and hear the difference between two slightly different sets of strings (.12 PBs, but from different manufacturers), used with one and the same instrument.
No cons that worth mentioning. I cannot judge for the other types of instruments but the acoustic guitar, though. Probably, some built-in cuts could be handy.
All in all: impressed, liked and sharing!
