I've used these mics now on a few sessions and found that the sound quality is excellent on both acoustic guitar and for drums. It has a very wide frequency response with great clear top ends, mids are fresh and and the bottom end goes on forever and stays clear the whole way down. We've also recorded some other percussion including triangle and bongos which I didn't think would sound that good based on their position but it come through extremely clear. Cymbals sounds fantastic! I want to also mention that the filters are a great feature and come in very handy. Again, these have only been used a few times but I haven't been able to stump these yet. These are great and I would recommend getting a pair of them, I've captured some phenomenal sounding tracks so far with mine.
