For a look at how the Pultec attenuation/boost trick works, see the UAD Pultec post. Be amazed at this mystical piece of magic! Or not, I mean, it’s just the way the original tubes worked.
If you have the UAD version as well as this one, you can mix and match components and switch them up from channel to channel. You get more “analog” variation that way! Stop being so “the same” (some free life advice for you).
