Nembrini looks great, any particular ones that you like?.. Currently using Overloud TH-U which also sounds amazing with my Ownhammer impulses (Heavy Hitter 2), especially their clean/crunch models are spot on. (They have a deal going on, worth checking). I tried all the Neural plugins though - they sound much better for the high-gain stuff, though harder to get them mix-ready.
I tried STL Will Putney, loved that - my wallet is going to hate me
I thought Parallax was the same as Darkglass, but with ease of use and a cab section (that can be bypassed), but I may be wrong..
