Acoustic guitar and vocals did not sound like good candidates for enhancers to me.

Probably not. I’d expect it to sound rather artificial, or just plain distorted.

@Gale Andrews

I’ve only ever seen or heard VST’s that do overtone generation. Are there any Nyquist plug-ins that do that under development?

Yes, in fact you previously commented on it (getting on for a year ago) Harmonic Enhancer - #6 by Gale_Andrews
