This one caught my attention. The Dev recently gave away the Lo-Fi Vintage Clipper which is really good. This amp sim also comes with a selected set of cabinet IRs. And you can load you own IRs for the cabinets too.
Nembrini Audio is a new company, but he has been around awhile. He programmed/modeled the Brainworx amps for Plugin Alliance.
I think I’ll demo it when I get a chance. I’m curious to hear what you guitar guys think of this one. Looks promising!
