Have it, used it for a while. Bought it at 29 $ for it’s sidechain capability per band. Nice plugin for the money (like most Waves plugins they’re more often ‘on sale’ than regular priced).
Since Pro Q3 is out (Pro Q2 was my favourite non-coloring EQ for years) I haven’t loaded it up a single time, even though it allows for more tweaking than Pro Q3 (no attack/release settings).
