Mk. III you mean.
Yep. It's really something else. I'm repeating myself at this point, but... it does subtly nice things to the mids just by being in path (that nice softening of "hard" digital mids that tape bouncing can sometimes accomplish) and one or two clicks of the limiter feedback control is a really cool trick to have in the bag. It adds a nice presence, richness and thickness to the tone (due to added harmonics, I believe?). You do have to be careful not to abuse it, though. Depending on the material, even one click is sometimes too much, and I haven't gone past 2 clicks yet. Doubt I will. It goes all the way to 10, which sounds quite distorted. For tracking, the extreme settings are probably useful as an effect.
I have only used it once as the sole compressor in a chain, and it worked very well. Usually, it is in path for tone (no GR) or doing 1-2b of limiting after my STC-8 or 2500 and before my AD.
I have yet to swap out the Sovtek tubes for Telefunkens, but I've heard it's a smart move, so I will eventually.
Definitely done buying compressors for a long while! Gonna start saving for Forssell's EQ I think...
