I have had this mic for over a year, tried it in many different circumstances, I had different voices on it, recorded acoustic guitar, voiceover and other small projects.
My verdict is that it’s not for me. I have tried to make it work for many months, over a year, especially my voice isn’t favoured by this mic. I had to do lots of mixing after recording with this mic, and it doesn’t take EQ very well. It is definitely not a good source out of the box.
To describe the sound: it s boomy, bassy, but bright at the same time. When comparing the exact frequency response of this mic to a U87, there is a dip in the mids on the Spirit, compared to the Neumann.
For important sources, I wouldn’t use this mic, but as a room mic, a drum overhead mic, for small projects and voiceovers especially, I can make it work definitely.
I sold it recently, but I’m disappointed I had to spend so much time with it and just not have bought a different mic, but I was refused the return.
I would actually try other Aston mics to be honest, this one didn’t work.
Overall, buy if you can return it, also don’t only record but try to mix the source and then decide if you want to keep it.
