5、idity. This combination is the most important single part of your guitars surroundings. Martin keeps the factory at a constant 45-55 percent humidity and 72-77 degrees Fahrenheit. If either humidity or temperature get far away from these factory conditions, your guitar is in danger. A rapid change i

6、n temperature or exposure to cold can cause small cracks in the finish. These are lacquer checks. We recommend the use of a hygrometer/thermometer to measure the relative humidity and temperature surrounding your guitar. As humidity increases, moisture content of wood goes up rapidly, causing it to

7、expand and swell. A gradual increase in humidity wont generally do permanent damage to your instrument. When very high humidity is combined with high temperature, glue joints could possibly become weakened and may even open slightly. If your guitar is exposed to high temperature or humidity for any

8、length of time, the glue under the bridge could weaken causing the bridge to pull off. Rapid changes in local humidity are what you want to guard against. If, for instance, you place your guitar near a source of dry heat, the humidity around it will drop much faster than it would naturally, although

9、 a sudden dry spell can have the same effect. If the moisture content of wood is forced down in a hurry, portions of it shrink faster than others, causing Proper Care of Your Guitar 3 cracks and open joints. Dont set your instrument next to a source of heat or hang it on a wall where it will dry out

10、. At all costs, avoid hanging your guitar on an outside wall during winter months. The wall will be cooler than the inside air. The result is a conflict between the temperature of the top and back, with potential damage as a result. Should the guitar be exposed to freezing temperatures, let it warm

11、to room temperature while still in its case. This allows the guitar to acclimate to room temperature more slowly, decreasing the possibility of wood and finish cracks Caution should be taken if you choose to use a humidifier to combat low humidity. Moisture in direct contact with the guitar could ca

12、use damage, as can the rubber or vinyl parts of a humidifier. We recommend storing your guitar in its case when not in use. Humidity is easier to control in a smaller space. Dont bother loosening the strings when putting your guitar away unless it wont be used again for several months. Constantly ti

13、ghtening and loosening strings quickly ruins their sound. The Martin hard case supports the neck and body of your guitar as evenly as possible. Its important that you dont let anything lie under the head (the tuning machine end), as this could damage the neck and body. Repairs to your instrument sho

14、uld be performed by a competent repair person. 4 Cleaning the Finish The best way to clean your guitar is with a warm, damp cloth. This will remove harmful chemicals. Your guitar is coated in the highest grade finish available and is sensitive. Any type of solvent, especially those found in plastic,

15、 vinyl and leather straps, will mar the finish, as will alcohol, citric acid, aftershave lotion, insect repellent and a number of related substances. Perspiration can also damage your guitar, so keep it dry. To polish it, use the special Martin polish and a clean Martin polishing cloth. We recommend

16、 wiping down your instrument and strings with a soft, dry cloth before storing to remove harmful skin oils. Products containing silicone should not be used. Tuning Machine Maintenance Tuning machines normally need very little care other than periodic lubrication. Enclosed machines, the type with a c

17、over over the gears, are lubricated by the manufacturer, but the open type should be lubricated once or twice a year. Just put a little household petroleum jelly on the end of a toothpick and place the jelly in the gears. Be careful not to use too much because it catches dust which can wear out the

18、machines. Some types of machines are adjustable for ease of tuning. The open type can be made harder to turn by tightening the screw in the middle of the gear. Check this screw every time you replace the strings because it can work loose. Most enclosed machines have a screw in the end of the tuning

19、knob that will make the machines harder to turn when the screw is tightened. Not much tension is needed, so dont overtighten the adjusting screws. 5 Inserting the Bridge and Endpins The strings are held in place at the bridge by a small notch at the front of each bridge pin. It is important that the

20、 pin slot be facing straight forward so the string is properly aligned on the bridge saddle. Make sure that the ball end of the string is pulled up tightly against the inside of the top before inserting the bridge pin. Too often bridge pins are hammered in so hard that they become wedged and split t

21、he bridge. After inserting the string and pin, a solid push with your thumb is all that is needed. The endpin is tapered and held into place by friction. It is not glued in. For proper insertion, hold endpin between thumb and forefinger, twist slightly while carefully pushing the endpin into the bot

22、tom end of the guitar. Do not use force. Do not hammer or tap endpin with any object; doing so may cause the wood to crack on the bottom end of the guitar. The endpin should be checked frequently to make sure it has not worked loose. Strings Different styles of playing demand different types of stri

23、ngs; but, unless you are a specialist in a particular style, your guitar came with strings that will normally give the best results. You may want to make your guitar easier to play and use one of our lighter string sets, but your bridge saddle and neck may have to be adjusted to prevent fret buzz. A

24、 classical guitar has much lighter bracing than the usual steel-string acoustic guitar, and using steel strings on it will literally pull it apart. 6 Strings dont last forever. As you play your guitar, you will notice its sound will gradually lose brilliance. It will begin to sound slightly muffled

25、because the strings have begun to wear out. Human skin moisture causes strings to become dirty and corrode, and this layer of corrosion eventually deadens the sound of the strings. At this point, the entire set should be replaced. Replacing only one string causes an unbalanced sound. Martin 6-string

26、 guitars are made for strings no heavier than medium gauge, and 12-string guitars should have lighter gauge. Adjusting the Action Often as a guitar ages, it seems to get harder to play. This is because the height of the strings above the fingerboard has increased slightly. This height, usually calle

27、d “action,” is very important to the playability of the instrument. However, if the strings are too low, they will buzz against the frets. The action can be adjusted at the bridge and saddle by a competent repair person. The adjustable neck rod is not for action adjustments; it is to be used to obta

28、in the proper neck relief and should also be performed by a competent repair person. Though straightening will have an effect, the neck should not be adjusted if it is already in proper alignment. 7 Necks and Tops Neck bow itself is often misunderstood and talked about as if it is the worst thing th

29、at can happen to a guitar. For some playing styles, a slight forward bow can prevent buzzes. With the adjustable neck rod, the neck can be adjusted for relative straightness. This is not considered to be a consumer adjustment and should be made by properly equipped Martin authorized distributors. So

30、metimes sighting down the neck gives the illusion of neck bow when it is actually within specifications. This is because the top will rise and fall with changes in temperature and humidity. This swelling raises the end of the fingerboard, which is actually attached to the top rather than the neck. I

31、f this should become too high, it might need adjustment or repair. The bellying of the top is normal and should be expected. The top is actually made with an arch. This will increase over a period of time due to string stress and/or high humidity. Heavy-gauge strings should not be used. If the belly

32、ing becomes excessive, the saddle and bridge may need to be lowered to improve the playability. Guitar Care while Traveling The guitar probably travels more than any other musical instrument in the world, and itll only be a matter of time before you take yours on its first trip. If youre going to ta

33、ke your guitar on the road with you, remember, its not just another piece of baggage. You have to make an effort to protect it. 8 If youre traveling by car, dont make your guitar ride in the trunk. Its much safer in the back seat because most car trunks are neither heated nor ventilated, so the temp

34、eratures can fluctuate wildly. Freezing or overheating your guitar is an invitation for a crack or warp to occur. Your guitar is assembled with glues that can be affected by heat causing breakdown and loosening of glue adhesion. Most commonly affected is the bridge. Air travel has become the most po

35、pular mode of commercial transportation, but protection of your instrument is important. Airlines dont set out to damage guitars intentionally, but a conveyor system cant tell a guitar from other baggage. Airlines may consider a guitar to be too fragile for their handling and may require that a waiv

36、er be signed which limits or removes their liability. Dont sign such a document if you can avoid it. Even a hard case cant always protect a guitar from damage from mishandling by individuals or commercial carriers. Occasionally you can bypass the usual baggage handling system by asking to take your

37、guitar to the boarding area where it can be tagged and hand carried to the airplane. Upon arrival, notify the flight attendant or customer service representative and try to retrieve it at the gate. Not all airlines give you this option. There are size restrictions on carry-on luggage. It must fit in

38、 the overhead bin or under the seat ahead of you. Some flight attendants may allow you to try the overhead bin, but if it doesnt fit; it may have to be checked as baggage. Loosening the strings and using a soft cotton packing material to keep 9 the guitar tight in its case will decrease the possibil

39、ity of damage while a guitar is in the baggage compartment. Martins hard case will help, but a good case is not a cure-all for careless handling or accidents. Using Guitar Straps Your C. F. Martin instrument is coated with multiple thin layers of high-grade finish. Our finish can be adversely affect

40、ed by interaction with certain synthetic straps and can also be affected by leather straps. The vinyl and synthetic leathers contain solvents that keep the material soft and supple. These solvents will transfer to the instruments finish and cause damage. Do not allow such straps to contact the finis

41、h. The best procedure is to always remove your strap from your guitar after use and store separately. Vinyl sofas, chairs, etc. should also be avoided. CAUTION: Damage could be incurred from prolonged contact of a Martin guitar with any strap.This applies also to contact with any other vinyl or synt

42、hetic materials, capos, accessories, furniture or other products. The string should be positioned with the bridge pin notch facing the string. Insert each string in its proper hole in the bridge. Keep the heaviest portion of the double winding facing away from the soundhole. How to String a Steel-St

43、ring Guitar 10 STEP1 STEP2 You might occasionally encounter an older guitar with a thin bridge or a string with a longer double winding adjacent to the ball end. Shown above is an old luthiers trick or remedy. An extra ball from an old string is placed over the string and drawn against the first bal

44、l. This will effectively back the string into the bridge, removing the heavy area of the string from direct saddle contact. 11 STEP3 The strings are held in place at the bridge by a small notch in the front edge of each bridge pin. Make sure that the ball end of the string is pulled tightly up again

45、st the inside of the top before inserting the bridge pin. Older Martin guitars may have small slots in the front of the bridge pin holes, but these are no longer necessary with the new style bridge pins. After inserting the string and pin, a firm push with your thumb on the pin is all that is needed

46、 to keep in place. The tension of the string and the proper positioning of the slot in the bridge pin will hold the saddle in place and the strings in proper alignment. After coming through the string hole, the string is wound one-half way around the tuning machine post. Clockwise for the three bass

47、 strings; counterclockwise for the three treble strings. SOLID HEADSTOCK If you have a slotted headstock, please skip to page 12. The string is passed through the string hole near the top of the tuning machine post. 12 STEP4 STEP5 After passing under the longer part of the string, the short portion is bent back over it. This will prevent string slippage. After the string is brought up to pitch (standard tuning), it may be clipped flush with the top of the tuning machine post. Note that a string shoul
