They're aimed more for Metal, but you can get some other good tones out of them. If you like to tweak a bit, they might be worth it....I need instant wows lol.
I got most them on their $5 deals. However, I haven't used any of them in a track as I have better amp sims and don't do a whole lot of metal. I just couldn't pass up the $5 deals .
On a similar note, I'm thinking of getting the Ownhammer deal going on.
