GUITARISTS TALK A LOT ABOUT RECORDING KILLER DISTORTION TONES, but
sometimes go kind of silent on the
subject of achieving great clean
sounds. Is the quest for clean so
obvious that tips and suggestions
are as welcome as a field mouse
swimming in your Captain Crunch? I
don’t think so. You see, crafting
great clean tones can be just as difficult—
and no less rewarding—than
dialing in the holy grunge. Here are
eight tips that point the way to
cleaner, meaner, and more freshly
scrubbed guitar sounds.
Honor Your Friend
Clean sounds don’t start at the amp,
they start at your instrument. So if
you’re one of those players who
never clean their guitar or wipe
down the neck, chances are there is
enough mung and drool glued to
the bottom of your strings and fretboard
to make the back pickup of a
Strat sound like a Tal Farlow album
being played underwater. Cut those
gruesome wires off, and clean the
frets and fretboard with the appropriate
cleaning products. Then, put
on a nice shiny set of your favorite
strings—my experience is that a .010
set or larger produces the best
clean sound—at least two days prior
to recording.
Go Direct
The path to a time-honored clean
sound is to simply plug your guitar
into a direct box and into your audio
interface or mixer. Your sound
should be round and full and innocent
of any overdrive. Some cagey
engineers add a bit of twinkle and
snap to the direct sound by
positioning a mic near the fretboard
of the electric guitar to capture
some unamplified string attack.
Recordists desiring a bit of goop in
their direct tones can switch out a
conventional direct box for a tube
direct box that adds a touch of preamp
tube bluster.
Take the Low Road
If your amp has two inputs, the
“low” input should operate at a a
lower gain compared to the “high”
input. Conventional wisdom dictates
that less gain equals more clean, so
let’s not argue with conventional
wisdom. Plug into the lowest-gain
channel so that your amp isn’t predisposed
to producing growl, grit,
and overdrive.
Exercise Balance
Everyone should know that, when
using amps (or amp emulations) with
master volumes, cranking the preamp
gain and backing off the Master knob
will only get you dirty. But how many
players actually experiment with the
levels of the preamp and master levels
so that they work to bring out the
hippest clean sound from your guitar?
The lesson is simple: Spin those
knobs until you’re bathed in the
cleanest tone your amp and guitar
can muster. If you want a chime-y
tone with just a hint of grizzled sizzle,
turn up the master volume to the
point where the sound starts to distort,
and then back off the volume
until the tone is cooked to near-pristine
perfection.
Think Subtractive
Depending on your amp or plug-in,
boosting EQ can sometimes get you
into trouble when creating clean
sounds, because the frequency
boosts may add just enough edginess
to sully your shine. I like to cut
midrange frequencies with extreme
prejudice, and then back off the bass,
as well. If boosting treble adds some
harmonic shimmer without introducing
spittle, then save your boosts for
the high end.
Mic Selection
In most people’s opinion, you can
always stick a dynamic Shure SM57
right up to the speaker grille, and
never feel the need for anything
better. There’s a lot of truth to
that—the SM57 is inexpensive, and
it sounds good on just about everything.
The SM57 does “hear”
midrange frequencies somewhat
aggressively, however, so take that
into account when you’re attempting
to capture your dream tone.
Clean freaks should also check out
large-diaphragm condenser mics, as
they typically deliver enhanced sensitivity
and more transparent highs.
An added little trick is to further
diminish the volume of the signal
chain by switching on the
condenser’s 10dB pad (if the mic is
so equipped). A lot of times, this
won’t be necessary—and, in some
instances an activated pad may lower
your ideal recording levels too
much—but if you’re paranoid about
“hitting the red” and introducing
some distortion to the signal path, a
pad can be a fabulous friend. If you
want a warm, smooth, organic, and
detailed sound, try one of the many
affordable ribbon mics on the market.
Mic Positions
You can obviously get a clean and
detailed tone by shoving a
microphone practically right against
the speaker cone, but it may also
sound somewhat jagged and dry. This
is not the time to go with “whatever
works,” and leave well enough alone.
You could be missing a wonderful
clean tone just because you’re too
tired, lazy, or preoccupied to experiment
with different mic positions. Try
moving the mic back a few inches to
allow a bit of room tone and “air” into
the signal. Or you could position the
mic off-axis to the speaker cone at an
angle of about 45 degrees to capture
some zing and chime. For less
aggressive parts, you could even
move the mic back a good yard or so
away from the amp. You’ll get a fair
amount of room reflections mixed in
with the source sound—the amp—but
the gentle wash of ambience should
make for a seductive timbre. All of
these mic positions will work whether
you use a dynamic, a condenser, or a
ribbon, and you shouldn’t stop with
these three suggestions. Make that
mic work for a living! Move it all over,
listen critically to each position, and
decide which clean tone gives you
the most bliss.
Persevere
If you’re working with amp-emulation
software, don’t be reluctant to go
beyond the presets. Some presets
are slathered with effects, compression,
and other pieces of ear candy
that may twist a tone from nicely
clean to annoyingly overwrought
(yes, even presets can take
themselves too seriously). There’s no
law against finding a basic “clean
amp” preset you like, and then diving
into the parameters to program a
pristine tone that’s exactly what your
song needs. No software engineers
will leap out from under your bed
and kick your ass. I guarantee it. And
if you think this tip is useless and
silly, then try to remember all the
times you’ve gleefully accepted
whatever an effects processor gave
you verbatim. Yeah—not so innocent,
huh? Happy tweaking!
