Fender being 250k and Gibson being 500k used to be the big difference,
but that's just like a smaller pipe for less water, and a bigger pipe for more.
Any 500k will handle anything 250k,
and the electronic differential is almost unmeasurable, not an audio that humans can hear,
and that's from companies using war surplus electronics to add to their previously just acoustic production.
But that's just pure electronics, not the artistic combinations that create sounds we want to generate, or recreate, with feedback.
After that, you're dealing with an electro-magnetic field you are hopefully focussing over your pickups,
and everything from pickup covers to wiring shielding has incrimental, detrimental, and extra-oriental qualities of phenomena and singularities.
We are now also expecting to sound good when we are digital.
What I explored in terms of electronics became inventing a "ground soak" that has obvious volume and tonal impact, so quiet, widening the feedback potential.
Also, within your pickups' magnetic field, imagine a "node" of self-centering magnetism, the input from less efficient wiring or deleterious specs of a part,
that is carried by your signal until it reaches amplification, becoming an unheard sub-distortion that breaks up your overall feedback output,
or prevents you from sustaining loud, never-ending echo, with other guitar driven effects.
Your sound, through the wires, looks like a small comet, centered along the wiring axis, surrounded by electrons that get eroded around the edge,
frictionalized by the cable, folding back elements of the signal envelope due to wire travel, and all that effects that.
Slowing your signal softens the sound and allows greater signal density, as does modifying your sound, say by phasing, to graduate your signal.
And then you do it all in reverse when it goes through the speaker coils.
While this aspect of my invention is unique, calling it a "ground soak" borrows nomenclature from Peavey.
Peavey invented a "plate" for electronic assimilation in a specific amplifier, and I saw the same parlance of ouput with my ground, hence "ground soak".
