Les
Paul Plays an Electric Tune (circa 1952) page 3
After
getting a grasp on one of the main components of Paul's guitar,
the solid body, I then move towards achieving a grasp on what
makes the guitar electric, the 'pick-up'. I first ask Paul about
his background with electronics. "It's been a hobby of mine
all my life. I used to take apart radios as a kid to see how they
worked, and I built my first crystal radio before I was even ten
years old. I've always been into refining the technology of sound.
Its something I've done because I like doing it, no other reason."
The quest for better sound that has led to the development of
an electronic pick-up started from him jabbing a phonograph needle
into the bridge of his acoustic guitar over fifteen years ago.
Paul talks passionately about his knack for electronics and begins
to explain to me the design behind his single-coil pick-up.
"The
pick-up that I designed is a transducer. Basically, all a transducer
is, is a magnetic device used to convert the energy produced by
the vibrating guitar strings into electrical pulses which are
then fed into the amplifier." Transducers are often used
in various sensory devices, but Paul had the idea of trying to
use in on a guitar. Despite Les Paul casually playing down his
knowledge, he is clearly competent in the subject. "My single-coil
pick-up consisted of a permanent bar magnet with a continuous
length of insulated copper wire wrapped around it several thousand
times," he says, "The magnet generates a magnetic field
around itself. Because the strings are made of steel, they interact
with the magnetic field. As soon as the string is struck, its
movement alters the shape of the field. Small pulses of electrical
energy are then generated in the coil. So if the coil is connected
to the amp, these pulses will travel to the amp." The pick-up's
function can be viewed similar to that of a bicycle pedal. As
moving feet use a bicycle pedal to create energy and motion in
the wheels, moving strings use the pick-up to create electrical
energy which is converted to sound.
