Use is given for voice and acoustic instruments. I use two microphones in Stereo especially for acoustic guitar (nylon strings and steel) and I like your exact. It's true that after having used the 33TM j'tais a bit surprised by the strong prsence frquences high, but the sound does not become hard.
The size of the capsule has a lot to the band and frequency drives is richer with the microphone capsule size. (APRS what I read on the net)

OVERALL OPINION

There are certainly better, but probably not this price. For non-professionals with an average budget is a good solution. I bought the two microphones as a pack, it's always better to possder peers.
