Random musings on intentional op amp misuse

[EBK]

If you decoupled those so that Vref stayed stable while the opamp supply wiggles, things might be different,

Exactly what I had in mind.

but I still think you end up hearing it. 

I suspect so too, but I'm hoping to hear it differently. 
There are definitely other ways of approaching this if I was just looking for some sort of threshold-based modulation.  I'm more interested in finding out what the op amp can do to the sound when it is being used unconventionally. 

Tired of building tubescreamers, big muffs, and fuzzfaces, etc.

Travis was recently hanging out at my shop and he told me that one of the Voice of Saturn things that he did (I think it was the filter) sounded really great for his prototype running off a battery and didn't sound as good when he added stuff to run off a wall wart.  He discovered that by adding the decoupling it totally tamed the circuit down and part of the raw goodness was the fact that it was pulling the rail all over the place and making cool noises.

Sometimes wrong/abuse sounds great.
