good:
It did attach well to the bell of my saxophone. The neck is flexible enough. It did give cracking sounds when shaping it first, but it felt normal. The build quality felt good.
bad:
However I positioned it, it felt like it can not cope with the huge dynamic range of a saxophone. It felt like it's just too loud for this mic. When positioned it off to the side from the air stream, I could dial in more gain, but it didn't improve the overall sound quality. The sound has a lack of bass tones, it is very thin.
It was picking up a lot of the vibration, the beat from the closing valves. When playing softly, it is more audible than the actual note.
I would not recommend it for a saxophone.
note: I was using it with the Behringer 204HD. The sound level resulting from my setup was too low, but it's to be seen whether it was the mic's or the audio interface's issue or setting. Only tried with my tenor sax.
