What the title says. I know that Stilwell has a dbx one, same for an Italian guy named sKnote, I think. Tried both, felt like they lacked some "weight" (can't describe it in more detail). I think UAD has one as well, but I'm not looking into UAD because of the activation complications. I also tried the comps in SSL channel emulations, but the attack isn't quite right for me. The applications I'm looking to use it are primarily drum shells.
