After hearing and reading all the hype, I finally picked up the Slate ML-1 to try out the mic emulations for myself. I will admit that some of them are pretty good and will most likely find their way into my sessions going forward, some were just ok, and a few sounded rather similar. I won't say which one I liked most, but just know that I have been recording using a C800G style mic, so that's typically the sound that draws me in...
For this test, I decided to record through the mic emulations instead of adding them after, so performed each take individually, and while there are subtle variances, the takes are pretty close in volume. I recorded through a Universal Audio Apollo interface in a treated room with a Mogami Gold XLR cable.
