hD is a distortion effect. It can also directly add note harmonics,up to two octaves higher and it contains a sub-octave generator.

The harmonic generators are optimized and located to enhance the distortion. They can also be used to generate 12-string guitar effects and as a note doubler. We developed a sub-octave generation algorithm specifically for this application. It is latency-free and is true to the sound of the input signal. It is located in the signal path post distortion. It adds depth without overwhelming the distortion.
