BTW, Wes often used a Super Reverb (4x10") in the early '60s and I

that the response time was super quick.
Absolute horse-shit. Sorry.
My Vibroverb definitely has
that kind of response, especially when compared to my '71 Vibrolux and
the Twin I owned years ago.
If you perceive a difference in "response time," it's imaginary.
The distance from the closest cone to your ear is the only
part of the system that can induce a delay perceptible to
a human being, at around 1.1 feet per millisecond. Delays
of less than twenty milliseconds or so are simply too short
for a human to hear; the delay through an amplifier - the
time it takes between your pick hitting the string and the
speaker cone to begin moving - is a fraction of a millisecond.
If you use a 25-foot cord and walk all the way out to the
end of it, you will probably able to hear a very slight delay,
since that would be around 20 milliseconds worth of
travel time between the speaker and your ear. While
input-to-output delay time in an amplifier is measurable,
it's simply irrelevant on the human scale of things. Your
nerves are *slow* compared to electricity...about 120
miles per hour vs. a large fraction of the speed of light -
more than 2/3 of c, in fact. If you stub your toe, electricity
in a wire would travel over 4500 MILES before the
pain impulse could travel from your toe to your noggin
via your nerves. (These are all BOE calculations; they
are certainly more than accurate enough for this discussion,
If you want to put it into musician-friendly terms, at
20 milliseconds per note you'd be playing at a speed
of FIFTY notes per second. That's so fast in musical
terms that the attack transients of the individual notes
would actually form a 50-Hz tone, which would be the
only thing you would hear.
Anything you hear or read about "amplifier delay" or
"fast cables" is bullshit. Humans just ain't fast enough
to hear that shit - period.
