very trippy that the first thing he mentions regarding pickups mirrors what i discovered regarding the use of a low output neck pickup in the bridge position. he used a modified gibson classic 57 + neck pickup with a 7.625k output and short A5 magnet in the bridge position, and i have the holmes 450 neck pu with 7.8k output in my bridge position.
strange coincidence, particularly due to the fact that Tom Holmes worked with Gibson to design those original 57 Classic/+ series pickups which he told me when i got my 450 from him back in 2002.

from the Tone Specific folks:
“57 Classic - The Problem
In 1990, Gibson quietly released what might be the
best humbucker ever made by a mass-market brand—the first-generation
‘57 Classic.
It had all the right stuff:

Plain Enamel wire

Quality magnets

Voicing that screamed late-‘50s soul
But it didn’t last.
Gibson execs, chasing margins over music, quickly swapped the PE wire for
poly-coated junk.
Then the magnet quality dropped. Then came the mass production shortcuts.
And now? Most ‘57 Classics sound
muddy,
muffled, and
lifeless.
The tragedy?
Tom Holmes designed the original. But he didn’t build them—and Gibson eventually
walked away from his blueprint.
That’s what happens when hobby players can’t hear the difference…
But our customers?
They hear
everything. You could do the same.....
OUR MISSION
Randall Van Dyke has studied every Gibson pickup design going back to the
1930s.
After analyzing decades of data and designs, he ranked the original 1990 ‘57 Classic as
Top 5 of all time.
So he made it his mission to rebuild it—
exactly the way Tom Holmes intended.
This is the pickup Gibson
should still be making—but won’t.
So we did it.
What makes this clone different?

Vintage-spec
Plain Enamel wire (not poly)

Period-correct magnets (no cheap alloys)

Dynamic, articulate, responsive
Lifetime warranty

Ear-voiced and tested—every single set
You’ll hear the difference. You’ll feel the difference.
And once it’s in your #1 guitar, there’s no going back. You'll buy sets for all your guitars.
PROOF POSITIVE
This isn’t Randall's first rodeo.
He’s the guy behind ToneSpec clones of:
Tom Holmes H450 & H455
Virgil Arlo Black Labels
Alan Hamel Masterwinds
He only clones pickups he believes are
legends.
The 1990 '57 Classic? It made the list.
Because when a humbucker nails that PAF warmth, cuts with clarity, and doesn’t collapse under gain—you build around it.
And here’s the kicker:

We regularly get trade-ins from players ditching their modern Gibson 57 Classics…
Just to upgrade to our pickups.
They know the difference.
And once you hear & feel it—you’ll never settle again.”

in the Tonex video Jim also mentions the 250k volume pot, which i also arrived at just by trial and error.
