Thank you for joining the
Mitchell family of musicians!
We want you to enjoy your instrument for many years to
come, so here is some helpful information regarding the
care, cleaning and maintenance of your new
instrument, along with a description
of the controls on select models.
Quality construction equals
incredible sound.
Mitchell guitars feature true dovetail neckjoint construction. This is a traditional building
technique designed to offer the strongest joint,
since more surface area is used to join the
neck and body block together.
Other appointments include high-gloss
polyurethane finish, real Abalone rosette,
thick Indian Rosewood fretboard,
die-cast tuners for great tuning
stability, and a limited
lifetime warranty.

Bracing patterns
The tops of most acoustic guitars use an
X-brace system, although there are variations
in type and style. This bracing pattern was
developed many years ago, and is the
standard for acoustic guitars.
Shifted X-Bracing System
A shifted bracing pattern moves
the bracing upward from the bridge
toward the headstock, a pattern used
in our MX400 exotic wood instruments.

Scalloped Shifted X-Bracing System
Mitchell guitars utilize standard X-brace
on most models; some include scalloped
bracing. Scalloping — the carving out of
excess wood in the center of the brace —
allows the top to vibrate easier, providing
additional volume as well as improved
bass response.

Tonewoods
Mitchell uses a wide variety of guitar
tonewoods, from select Spruce to exotic
Koa, Bubinga and Ovangkol. Read on
to learn more about the unique tonal
characteristics of the woods we use.
Rosewood
Traditionally used for its more
pronounced bass response,
rosewood is very popular in
acoustic guitar design due
to its tight grain and superb
density.
Mahogany
Light weight and low density,
Mahogany is often used
in acoustic instruments. It
brings bright treble and a
balanced bass response to
the sound.
Cedar
One of the softest woods, it
provides a mellower, darker
sound and is used almost
exclusively for classical and
acoustic instruments.
Spruce
Spruce is most popular
for guitar tops as it offers
the best strength-to-weight
ratio. It provides outstanding
clarity, perfect for picking
or strumming on acoustic
instruments.
Koa
The distinctive striping of Koa
makes it a beautiful tonewood to look at. Its sound
characteristics include a
round bottom end, with a bit
more “sparkle” on the high
end similar to Mahogany.

Ovangkol
One of a variety of exotic
tonewoods, Ovangkol is
also known as amazoue or
amazakoue. Ovangkol’s tone
resembles the warmth of
rosewood with the midrange
of mahogany.
Bubinga
A sought-after tropical exotic
wood with an interlocking
grain, it provides a great
low end, gorgeous mids,
and a bright, ringing treble.
Quilted Ash
Prized for its cosmetic beauty
as well as its bright, snappy
tone, Quilted Ash is becoming
more popular in acoustic
instrument design.

How to change your preamp battery
Your Mitchell acoustic-electric instrument may utilize an active
preamp system, including a 9V battery as the active power source.
When the Low Battery or “batt” indicator light comes on, it is time
to change the battery.
Fishman
Replace the battery by flipping open the preamp body using
the latch located above the Fishman logo. Be sure to observe
the correct polarity during this installation. More information is
available at www.fishman.com.
AT3000/CE304T
Replace the battery by loosening your bass-side strings. Reach
inside the guitar body (through the soundhole) to the back of
the preamp. The 9V battery will be located in a small metal clip.
Remove the battery from the clip, remove the lead wires, and
replace with a fresh alkaline battery.
To conserve power,
unplug the instrument
and turn off the tuner
when not in use.

How to put a strap on your Mitchell guitar
Tie one end of the supplied strap onto the neck of the guitar under
the strings, above the nut and below the tuning machines so
that it does not touch the strings. Make certain it is tied securely.
Slip the buttonhole of the other end over the strap button at the
bottom of your guitar until it is securely attached. Once secure,
adjust strap length for playing comfort.

Maintenance Manual
Strings
If your strings appear dirty or produce a dull sound, replace them
with new ones. It is recommended that you change them one at a
time to keep string tension on the neck.
Be sure to replace with similar gauge strings (see chart below).
If you replace with a different string gauge, a truss rod adjustment
may be required. We recommend a qualified guitar technician
to handle this. Consult the Support page of the website http://
mitchellcusthelp.com/ for more information on factory string
gauges and more.

how To change strings
Loosen the tension on your current strings. Then, using a string
puller/peg winder, pull the bridge pins from the bridge and remove
the strings.
Place the new string in the bridge pin hole. Re-insert the bridge
pin while pulling the string to remove any slack. Pull the string up
across the fretboard and thread through the tuning machine. Hold
the bridge pins in
place for each string
while tuning to pitch;
this will eliminate
the bridge pins being
pulled out of place
by string tension.
Maintenance Manual
Neck
All Mitchell guitar models feature dual-action adjustable truss rods.
The truss rod allows you to adjust the neck to counter the tension
caused by the strings. The truss rod may need to be adjusted if you
change string gauges, or if you lower or raise your standard tuning
pitch below A440. String tension changes may also cause fret buzz.
how To Adjust the Truss rod
Remove the truss rod cover and locate the truss rod nut.
Place a 4mm hex wrench and adjust as follows:
Clockwise tightens the truss rod, causing an convex bow.
Too much may result in fret buzz and dead frets.
Counterclockwise loosens the truss rod, causing a concave
bow. Too much may result in high-action and poor intonation.
Truss rod tension can be measured by using a capo at the first
fret and holding the strings down where the neck joins the body
(14th fret). There should be .3 mm to .5 mm of clearance at the
8th fret.

Cleaning
Action on all Mitchell guitars is set at the factory to our
specifications, however some players may prefer higher or lower
action, depending on playing style. Also, temperature changes
and moisture can affect string height. Below is an action guide for

Regular cleaning of your guitar is an
important way to maintain the finish and
extend string life. Always wipe down your
instrument after playing to remove sweat,
which may contain acids that will corrode
strings and metal parts/hardware of the
guitar. Gloss finishes should be polished
with products designed specifically for music
instruments, along with a soft, treated cloth
or cotton rag (an old T-shirt will work fine).
Non-gloss finish instruments should be
wiped with a dry cotton rag only.
