I bought a pair and used them with a Church Audio 9100 preamp into an R-09 with good results. For $80 mics they sound pretty nice. They do pick up a lot of bass, so beware. But I used 'em without rolloff at a pretty bassy small club show and the recording came out surprisingly good. That said, I've only taped a handful of shows with 'em (all small clubs), so I don't have a lot of experience with their sound.
