Had it for about two years now.
Bad stuff: Had to return the first one I got because the push button on the rotarypot didn't work, so I couldn't get in the menus or adjust other frequencies. Thomann did a great job handling this. Got a new one but it had the same problem. Annoyed, I took off the knob and tightened the nut. And that fixed it, no problem to this day. So maybe some issues with final QC from SourceAudio.
Other than that, really powerful utility with noise gate, limiter, tuner, alot of useful routing options and probably more functions that I havent used yet. And most of it midi controllable.
I use it to change sound pre/post distortion, brighten up my HB guitar for cleans, tuning, as a boost, compensating volume between different sounds etc.
If you just want a set and forget eq or just use one setting, maybe this is a little bit overkill. But if you want alot of utility functions in one small package and you use midi then definitely try it.
