That's my first Emma effect pedal. And I'm surprised. Before it I had MXR - the same suboctave fuzz. When OKTO-NOJS comes to me, I say goodbye for MXR. So great quality of sound, and so nice "brick" feeling of the pedal construction. It's really solid. Octave sound there can be variable between two kind (modern and "boomy"), as many other octave pedals use. Fuzz part has five controllers and very flexible. I use it for the bass, and really one of my main pedals in the pedalboard. Now I gonna try more Emma effects. So, really recommend to use!
