This is the MKII, Softube just released the MKIII (1299!!!) so this older model is now going for $620 new.
It requires a plugin which I believe Softube gives for free now, but if not, I can transfer my license. You need an iLok account to use this and it works with all major DAWs.
It supports about 60 of softube’s plugins.
I used to use this a lot and now find myself keeping it in a drawer more often than not.
