Ronald Passion is a developer who’s rapidly growing a fan base thanks to his top notch (and wildly diverse) free plugins.
Here are two pretty wicked guitar preamps to add to your collection.
British and American amp styles available here, with lots of control over your tone (hyper and ultra drive modes anyone?), plus a couple of other ways to shape your sound.
Personally, I haven’t tried them out yet, but people seem to love his stuff, so have a crack!
