This was one of my favorite free guitar amp sims in version 1. I wasn't too crazy about version 2, but Voxengo 3 is an awesome update of the original, excellent for any sound you can imagine in your head, endlessly tweakable on account of the parametric EQ tonestack that replaces the usual preset bass-mid-treble-presence layout. The sound engine is a major quality upgrade to an already great sounding amp sim, and the new dynacab feature, while a little confusing until you RTM, really adds depth to the speaker possibilities, including loading your own IRs.

CurveEQ has beyond exceeded my expectations. I got it through the premium package and I've tried so many of the plugins and they're all really really good, but curveEQ is just next level.
First of all, drawing the EQ line is absolutely genius. So intuitive and easy to modify and work with. Redrawing small sections of the curve is insanely easy and it's just fun to use.
Second, the EQ sounds perfect. I don't use that word lightly. I've tried virtually every combination of plugins and the music always sounds really cool but I end up needing like 3-4 plugins going to get perfect sound, and my Macbook just isn't capable of doing that much processing.
After setting up CurveEQ I found that I just had no need for any other plugins because of how complete the sound is. It balances the bass with the highs perfectly so you never feel like songs are too heavy or too light. I can pick out every drum kick of this Biggie song I'm listening too, and each component has just the right amount of kick and punch to it.
Wow! Voxengo knocked it out of the park again with Peakbuster. I've long recommended TEOTE, and this seems to be the perfect-pairing! It's different enough that you want both.
I can't explain what it does -- all I know is it makes my songs sound better. Not in a way that has artifacts, like some other 'betterizers'... Peakbuster "just works" without adding any fatiguing side effects. It adds the kind of magic that when you turn it off --- you turn it back on as quickly as possible and think, "What would I have done if I didn't have this?!"
You think you're done with your mix and then Peakbuster adds something better that you didn't even know you needed, but once you hear it you don't want to remove it.
I'm using Peakbuster with TEOTE, Marquis Compressor, Elephant Limiter, and Span Plus. I EQ on my submix busses, so that's a perfect Voxengo mixbus mastering chain for me.
I'm always happy when I get a plugin that I can use on every track, and all 5 of those fit that bill. Peakbuster is outstanding!
