I got the Audio Assault stuff from them.I’ve got the Neural DSP plug-in, but I haven’t gotten comfortable using it. It’s fairly cpu heavy in real time (small buffer). Some of the presets have been pretty good. I seem to get lost trying to make the cab sim work with mic selection and placement.
I also use Ugritone IR. Some are better than others. They’re mostly guitar focused.
I think I downloaded the Does it Doom free IR pack too, but haven’t spent much time with it.
I recently started going through Guitar Rig 5 again. There’s decent presets in that VST. The current GR6 version adds some extra bass options and might be worth a look.
Duality Bass amp sim? Pretty straightforward. Got some cabinet IRs as well. If you ever want some of this stuff just lemme know, I can send you some of the stuff that doesn't require the license to run.
It was cheap as all hell so I also got some guitar amps for my SO.
I also found the Parallax stuff from Neural DSP but it has that heavily baked in sound from Darkglass, I think I want to stay the heck away from that because it seems kind of limiting. There is also the Aurora Mammoth which sounds killer but you gotta fork out 80 dollars for it so I haven't gotten it... yet.
And, of course, the Bassforge Hellraiser for that super klank for about 40 dollars but again, I haven't gotten it... yet.
