In Reply to: RE: I perceive that you know more about electricity than I do. posted by Lew on December 15, 2015 at 07:08:52
I'm trying to stimulate discussion of the various possibilities, not trying to have it both ways. I haven't decided which if any of these I believe.
Is the BGT interacting with/charging hidden parasitic circuits?
Is the BGT a steady state subcircuit that resonates with the AC of the music signal to cause perception of enhanced dynamics?
Does the BGT somehow pump electrons into the ground plane, more than would normally be present, allowing the circuit to react to transients more quickly?
Is there no effect at all and all of us who hear something are suffering from expectation bias?

I made a bunch of the newest versions for the stereo and TV and, on a lark, gave one to a co-worker who plays electric guitar. He plugged the BGT into a parallel input of his amp and, over the space of several days, tried a number of different guitars. His main comments were that it seemed the amp picked up more drive with added detail and that the midrange, always being a little weak, was suddenly filled in. (Like an EQ shaped like a smile is now a flat line.) He even forgot it was plugged in one time and wondered why his axe sounded different. And he likes the change in sound - or at least, I haven't gotten the BGT back after about 2 months!
Now, here's the clinker: the BGT did this on all of his guitars but one and with that one he could not tell any sound difference, with or without. I had built up a pet theory that it was acting on the equipment it was plugged into, but if it shows no difference on one sample, the BGT is not filling in a deficiency of the guitar amp but would seem to be heading upstream to influence either the signal or the guitar producing that sound. And what is it that makes that one guitar immune, so to speak?
Others are free to ponder and suggest ideas; I find the whole thing fascinating, even though I haven't a concrete clue how it works - but it does. On some things.
Interesting. Same thing I hear - fuller mid-bass and more impactful bass.
Now if we can only figure out why...
