Looking into one of these as an extra gain stage to kick in for leads in front of my amp. Anyone tried one? How is it?

I've read mixed reviews. Some say it's great, warm, and tubey. Others say it's fuzzy and harsh.

On the demos, it definitely seems like it's voiced bright, which I don't mind for some added sparkle for leads... but, if you've tried it, is it too bright IYO?
