I've used this mic for a couple of years now and I've recorded acoustic guitars, electric guitar amps, clean and screaming vocals. The mic is really versatile and works well. Only one I've had a bit of trouble with is the screaming vocals, which tend to need quite a bit of EQing because they tend to sound a bit dull (might be the singer too!)
I'd highly recommend this as your first studio microphone. Can be used for voice communication as well!
