This is an inexpensive mic from Electro-Voice. Looks very cool, I heard on vocal, the sound was very nice, somehow condenser like. The specification suggest me, maybe works well for double bass. http://www.soundonsound.com/sos/may06/articles/emvmics.htm
I have both the raven and the cardinal ( the condenser one that looks like the raven but its red). the cardinal has more output and sounds much better than the raven, good thing about the raven is that its dynamic and doesnt need phantom...but still, i would go with the cardinal. Nuno
