I'm not sure whether to take the plunge with this again. My previous year pass ran out in March and since then I've been paying month to month ($15) because having watched so many of the videos during the first year, I'm not sure if there's a year's worth left in there for me. There doesn't seem to be many new courses added in the course of a year, at least none which are relevant to me. Seems like there are so many courses they could be making which aren't there - Guitar Rig springs to mind. And I would have thought they'd have way more courses on EDM styles than they do, given how popular the genre is. Still, there are some videos that I'm going back to for a second watch, which is why I'm keeping the monthly subscription for a while. An example is Eli Krantzberg's excellent reverb course, which is well worth a watch if you haven't already. It's definitely one of the finest courses on the site and an all-access pass is wasted by not watching it!
I have a long wish list for Groove3 courses - Jamstix and Geist would be nice for example - but to be honest I think a year's pass is more than enough to watch everything that's relevant to you....like I said they'd have to add a lot more new content for me to justify buying another year.
