I've been following this guy for a few years now, including buying some video lessons from him a while back. This series "Where Does The Tone Come From In An Electric Guitar" has been endlessly fascinating - quite literally piece by piece, he's either isolated or removed components of his guitars and amps and run the resultant unit through a couple of visualizers. Key takeaways were that, with the same strings and pickups, you can literally stretch some strings between a workbench and a counter and still get 99% of the tone of a solid guitar...and that nearly every change you make in an amplifier cabinet
will impact the tone more than anything you can do to the guitar. To put it into a gross oversimplification,
only the magnets matter.
This video throws it all out the window by echoing something that I learned on Reddit of all places: Any and all guitar tone you're chasing has been recorded. When I was searching for a distinct country tone, I discovered that it came from plugging a Telecaster directly into the board and adding effects in post - in other words,
literally nothing I could ever do would get me that tone. The tone I was chasing exists only in a studio. What Jim puts forth is similar, and he actually demos a bit of mic placement throughout the room and the impact on the "tone" of the video...but, Youtube compresses the shit out of sound, so even when he's showing his visualizers and waveforms, there's no guarantee that any subtlety will be translated through Youtube.
Now, when I'm saying all this, I also used some studio monitors (that I picked up when I worked at the guitar shop all those years ago) in a couple of actual blind tests in Youtube to pick up an amp...Even translated through Youtube, the bloom of a tube amp comes through the recording. But, for me, the practicality of this video series (and what makes it so fascinating to me in the
relentless pursuit of tone) is being shown that, basically, tone doesn't exist. Any upgrade or variation can be overcome 99% of the way by adjusting something.
