Unbelievable

PhD  the pic up are not bad , I leave the guitar the way it is , any mods on guitars in my opinion, degrades it . Not original ,anymore I have Gibson’s already, sorry for going off topic.

I have used varnish on black colored tweaks for the past decade. Different colors give a different sound signature. The neutral colors are white or black. White has an open and transparent sound while black has a blacker background, but also dark, muddy and veiled sound. By using varnish on top of black paint you compensate for the veiled sound and add clarity. This gives good balanced sound.

Interesting....

Noise is the time varying quiescent output in the absence of an input signal and/or independent of the input signal. In speakers, noise, by definition, is essentially 0, unless you are claiming it is picking up seismic vibrations from the floor and re-radiating them, on which I will call them out, because the floors and walls will be a far more effective radiator for that, and because that is an external stimulus, so would be akin to showing a frequency response with a truck driving by.

If they want to claim it improves THD, or IMD, then that is within the realm of believable as those are signal dependent properties.

Given the ridiculous claims that audiophiles accept without calling suppliers out on, is it any surprise that some marketer for a main stream brand would do the same .... without any justification or measurement to support it?

Phenomena dont need a justification passport to appear ….  :)
