When one of the world's top microphone manufacturers makes a premium mic that is purpose built for tracking vocals, the world should take notice. I have no idea how this mic seems to be such a well kept secret, but as you might expect, it is an incredible sounding mic. It was also designed with a very wide sweet spot and a minimized proximity effect that just makes the job of recording easy. I have even done voice over work with it, and it just sounds like velvet. As with all Shure products, the build quality is outstanding. There are a lot of cheaper mics out there, but when you're ready to step up your game, this one is worth every penny.

Been using this for a few weeks now into a UA pre. There is nothing this mic cannot do. Female vocals -beautiful, male vocals -perfect. Shure made this mic for tracking vocals and it does it this with precision. No eq necessary. No audible noise, no distortion, no proximity effect and it looks sexy. This is the mic to buy when you get serious. I'm selling my blueberry. Bury me with it.

Real deal

Been using this baby about 4 months with no complaints at all. Running it into a adl 600 and the sound is pretty close to what I was looking for. It wont be the only mic in my locker but its definitely a keeper. Female vocals come out beautiful, male vocals little to no eq required. Genre in use is hip-hop.

Sweetwater Advice

Nick Church

With a very sweet clean mid-range, controlled presence-lift, and an almost non-existant low frequency proximity effect, the Shure KSM42 mic should be given very serious consideration as a perfect all-round vocal mic in any studio's mic locker. Try it, you will not be disappointed.
