Ah I see! Ok that's sort of how I imagined it to work, at least on the output side the opamp was doing the heavy lifting so to speak. Honestly, I could use at least my own version of IanSpice; it would save so much time. Normally I end up understanding how things work, but only after weeks and weeks of banging my head on any hard surface nearby.
In terms of oscillations, I mistook your previous post to be of the high-frequency instability variety. That's what I was referring to with the bandwidth limiting cap. But ya, in hindsight it makes more sense that the low frequency kind would be the one below zero. Now, in LTSpice, the LF oscillation does shoot below 0 when signal is removed, so I wonder if your original suggestion might be correct?
And you're correct that the oscillation would cause a weird tremolo effect, my hope is that that sounds odd and interesting.
