I'm also looking to replicate the slight grit of my Accountant compressor, maybe with an amp sim or maybe with the barest hint of OD. SVT or fliptop might do it but I am finding it difficult to dial in that tiny tiny amount of grit on those - seems to go full drive very quickly.
I'm finding the tube screamer model does this quite nicely, if you dial in healthy amount of clean signal. The lack of low gain drive was something I always felt was missing and trying to dial it in from other drives sounded artificial.
