This microphone sounds great... once you have the preamp to go along with it. The descriptions for the 520DX make it sound like you can plug directly into an amp, but I don't recommend this at all. If you do so you will get tons of feedback and a really tinny sound. However if you add a microphone preamp between this mic and the amp, you will get the sound you're looking for. I've had very good luck with this preamp: http://amazon.com/gp/product/B0002GZZNY/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
