Hi Folks,

Came across this recently:

https://positive-feedback.com/audio-discourse/the-pass-h2-harmonic-generator/

Seems pretty simple! Anyone here tried one of these?

Cheers,

Chris

Ludicrous! Again it demonstrates that growing a beard and saying stupidities in a loud voice attracts a number of believers...

This thing indeed delivers harmonics, and yes, mainly 2nd-order.
Many people think distortion is a nice thing, I can hear that in many records, call that grit, urgency, lift, tension, whatever, I hear it as an annoying screech in the background, particularly in the presence of different signals, which results in intermodulation distortion.
This type of effect should be limited to solo monodic tracks (not piano!), where intermod is not too likely.
Electric guitar is a different issue; the heavily distorted sound of "clean" guitar (typically about 10% distortion) is an acquired taste.

Have you looked at any of Nelson Pass's designs?? Some of them are pretty novel.

Sure I have; never been impressed.
His stock-in-trade is H2, wants to put it everywhere.
If he was so good, he would be designing swith-mode amps; that's where the real challenge is.
