Re: Polarity invert toms ?

 

Here we go.

Polarity in the context of feedback (according to the Johnny model of feedback) shifts where the narrow potential feedback nodes express, related to the path length of the acoustic path and speed of sound in air. So feedback can occur for either polarity, just at different spot frequencies related to wavelength and path.

This seems consistent with your reported experience so I will stop while we are in agreement.
