  1. Top Notch 5 Star Review

    Posted by on Jun 14th 2021

    This is the nicest, coolest microphone I have in my collection so far. Sounds superb on everything I’ve tried it out with. Requires a heavy duty boom stand because it’s like a small cast iron skillet. Pairs with the Atlas Sound stand nicely. High output for a ribbon mic! Which is great. Now I know why all great engineers recommends this microphone for every studio.
