My CBV001 just arrived this afternoon and, wow, so far loving the different flavors of edge feedback possible with it. I use feedback a lot in my LZX system, but it often tends towards one specific look. Whereas pretty easy to quickly dial in a lot of variety with this little guy. Great work, @syntonie!
