A friend of mine, a true iron man of music— engineer/musician/singer/songwriter/tech—has a horrific secret: he’s Beethoven-deaf. Currently he works as a guitar tech for one of the most famous guitarists in the world. I can’t reveal his identity because it could cost him his job if his boss knew that his tech couldn’t hear the highs coming out of that stellar rig. Here’s an example of his staggering deafness: you know that scene in the movie Poltergeist where the little girl gives that prolonged scream after she encounters the ghost? When my friend recently watched that scene, he heard nothing; he literally thought his TV had stopped working. He got up off the couch and walked up to the TV to investigate. When dialogue kicked in, he discerned that the problem was his ears, not his television. That is cochlear damage.
There are thousands of tiny hairs in the cochlea
that are stimulated by the pressure of sound
waves, like wind moving in a wheat field.
Different frequencies of sound stimulate specific
sections of these tiny auditory hairs, causing
them to move; this discharges electrical
impulses through the auditory nerve, which our
brains interpret as sound.
Here’s the bad news: these tiny hair cells and
auditory nerves are easily damaged by either
a sudden loud sound (such as a feedback
spike), or an extended long period of time
exposed to loud sound (like regular gigging).
When these tiny hairs get bent or broken, they
send electrical impulses randomly to the brain
which are interpreted as sound, even though
there might be a complete absence of sound.
That’s tinnitus, the ringing in your ears. I’ve
heard a theory that it is a little bit like phantom
limb syndrome—you know, an old soldier still
reaches down to itch a leg that was blown off
in Da Nang forty years ago. The line to the
receptor still exists, even though the original
receptor is gone (in this case the tiny auditory
hairs). These receptor lines are active and will
interpret any stimulus as sound. For example,
you squint your eyes just right, the damaged
receptor in your cochlea is stimulated, and you
suddenly hear a high B-flat note ringing loud
and clear. Cochlear damage is almost like a
faulty electrical connection.
A live stage punishes your ears, making
cochlear damage an occupational hazard.
The hell of it is that often it’s not even your
amp that’s robbing you of your precious
hearing. It’s your drummer’s bashing and the
occasional brain spike of painful feedback.
Even the warm lows of the bass that don’t
feel painful are still laying waste to part of
your cochlea. Unless you’re on a tour with
a killer in-ear monitor system and a quiet
stage, protecting your ears comes down to
wearing earplugs. Playing guitar and wearing
earplugs is the sonic equivalent of suiting
up with a couple condoms. Sure you lose
sensation, sure it feels unnatural,
sure it’s not as fun—but
much like our Trojan friends,
these foam protectors should
be kept with you at all times.
I’ve advocated earplugs since I
was fifteen, working in a music store
employed entirely by musicians. I was the
only person on staff who could hear the
phone ring! I began gigging with an older coworker
who set his amp with all highs and no
lows because 1K and above were gone in his
ears. Earplugs were the only safeguard against
sharing the fate of my old rocker co-workers.
I bought expensive fitted plugs but found the
cheap, yellow E-A-R Classics work the best.
Now I buy plugs by bulk, stashing them in all of
my guitar cases, glove box and backs of amps.
Every pair of jeans I own has earplugs in the
pocket that go through the wash-and-dry cycle
then back in my ears. I’m the geek you see
wearing earplugs at bars when the music gets
loud. They not only protect me from deafening
music but also from the drunken moron standing
next to me shouting in my ear. I put them
in when I board a plane to avoid the painful
announcements from the flight attendants.
Because earplugs color your tone by stealing
highs, you have to set your rig plug-free, really
playing with all of your settings: clean, dirty,
etc. Stand back as far as your cord will let you,
giving your ears the highs of the tonal spectrum
that your audience hears. Once your tone
is dialed, don’t touch it, trusting that your rig
sounds like God Himself rocking.
The other day during sound check for the
Nashville Star Live tour, I set my rig sans plugs
on a big, open arena stage where you can
move some air. I cranked my ValveTrain amp up
to six and it really came alive—the kind of good
tone that almost makes you drunk. I cranked it
up to eight and I began hearing cool overtones
that aren’t normally there. I was beginning to
feel a little giddy. I cranked it wide open and it
became sublime. Inspired, our drummer came
on stage and began pounding away, then our
bass player followed, and it turned into a Spinal
Tap jazz odyssey. I had more fun during the
trance-inducing ten minute jam than I had had
for the entire tour. We blew through sound
check with the singers and kept on jamming
until the stage manager ran us off so they could
open doors to let in the crowd. As I flipped my
amp to standby, a buzz in my left ear swelled
into a clear F# and I wondered if I would ever
hear that tone naturally in a mix again.
