Quality Musical Instruments Since 1986 Maintenance Manual www.MitchellGuitars.com 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. Maintenance Manual 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. www.MitchellGuitars.com 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. Maintenance Manual 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. www.MitchellGuitars.com 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. Maintenance Manual Controls for acoustic/electric models All Mitchell acoustic/electric guitars feature premium preamp electronics, designed to give you complete control over your sound. www.MitchellGuitars.com AT3000 Mitchell Preamp CE304T Mitchell Preamp with Tuner Fishman Prefix Plus-T Preamp with Tuner MD100CE, MD100SCE, and MD100S12E • Master volume slider • Hi & Lo EQ sliders • Low Battery indicator MX400 • Master volume knob • 3 band EQ (Bass, Contour, Treble) • On-Board digital tuner MD200SCE, MD300SCE • Master volume knob • 3 band EQ (Bass, Contour, Treble) • Phase in/out switch • On-board digital tuner More info available at fishman.com Maintenance Manual 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.

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. www.MitchellGuitars.com 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. Models String Gauges Acoustic Dreadnought .012 – .053 Junior Acoustic Dreadnought .011 – .052 Mandolin .010 – .034 Banjo .010 – .010 www.MitchellGuitars.com 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.

Also, temperature changes and moisture can affect string height.

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.
