This article is from the James Taylor FAQ, by Joel Risberg (firstname.lastname@example.org) with numerous contributions by others.
From Sergio Ramirez (email@example.com) citing a Spring 1992
"Guitar Extra" article:
For two years previous to the interview he had been playing guitars made
by a guy in St. Paul, called James Olson. He used those guitars in "New
Moon Shine." He played a Yamaha for a while, but lately he had been
playing the Olsons only. He owned three Olsons, one of each of the sizes
Olson made: a "parlor-size," a dreadnought, and a cutaway.
He was using a Lloyd Bags pickup under the bridge, and when playing live
he used a Pendulum audio preamp. This was a 4-band equalizer with a
variable notch filter that helped him take out "some of the 'oinky,' sort
of unpleasant metallic sound that you get out of a piezoelectric
He used to use a dreadnought guitar, and loved its profound sound, but he
found that with a piano and bass player he was taking too much room, so
he went for a smaller, more concise guitar with a narrower and prettier
range; this way the guitar can make a statement without getting tangled
up in bass and piano. But when he drops the low E to a D, he goes back
to the dreadnought.
