In conjunction with my friend and colleague at Herzlich Labs in Denmark, I am assisting with assembly and US distribution of this awesome module. Save some dough on shipping and get it right here!

For once, there isn't much to say - what you see is exactly what you get. Four passive attenuators, in 4hp. Perhaps the most useful utility in any system, and here, you get four of them! Fully open, fully closed, or somewhere in between, Qatt will put your signal exactly where you want it to be.
