Kuassa's Amplifikation Vermillion is a great sounding emulation of a vintage tube combo amp. Rather than emulating a specific amp, Vermillion, to my ears, does a nice job with a range of clean to crunchy tones reminiscent of a lot of Fender tube combos. The clean tone sounds nice and crisp like a Fender which I like - I don't think it does the sterile clean of a JC-20 nor does it do the brash jangle of an AC-30, but if you like Fender deluxe reverbs or Rivera amps, you will like this plugin. The Spring reverb sounds nice, the tremelo sounds good and is sync-able. The more distorted presets also sound pretty good to me. My only gripe is that there is not a ton of tweakability between the presets - the gain knob and the eq knobs don't affect the tone as much as a real amp, so you really need to explore the presets to find a sound you like, rather than tweaking from scratch. That said, I do really like the sound of this amp, especially for 60's inspired tracks or cleaner post-punk and indie sounds.
