The 101 was the first mic pre I ever bought way back when I first got my first PT rig. Up until that everything I recorded with through an old Mackie 1604. Say no more.
When I got the 101 i also got my first condenser mic, AT4070. I used those two on everything and even now I still love the sound, especially the 101/4047 on acoustic guitar. I have since purchase a few more mics, the best of which is a Rode Classic 2 and I also purchased 2 API 3124+. I love the APIs on everything with any mic, especially drums and bass. However, i still use the Grace for acoustic guitar and vocals occasionally. The Grace is definitely different, i find that vocals seem more "in your face" than the API but the API is way smoother and less edgy if that make sense. I have used the Grace on HiHats with an Octavia mic, very nice indeed. Put the hats exactly where I wanted it but not annoyingly.
Sorry this is my first critique.
