8、l, and is affected dimensionally by changes in the amounts of moisture it contains. Fine guitars made from solid woods, are without a doubt, more susceptible to the effects of changes in humidity than laminated instruments, and therefore require ongoing attention to their condition. The moisture con

9、tent of wood is determined by the relative humidity and temperature of the surrounding atmosphere. Relative humidity is expressed as a percentage of airs capability to hold moisture. For example, 30% relative humidity means that the air is holding 30% of the moisture it could possibly hold at a give

10、n temperature. The moisture content for wood and the relative humidity for air are measured quite differently. In wood, a 6% moisture content is present at 30% relative humidity and 72 F temperature, (about 22.2 C). Protection from Temperature and Humidity The greatest threats to a fine wood guitar,

11、 are extremes of, and rapid changes in, temperature and humidity. High humidity can cause softening of the glues used in the construction of the instrument. Also, as the woods absorb moisture from the air, it can cause the top and back, especially on flat-top and classical guitars, to expand and ris

12、e - making string action high. Conversely, if you live in or travel with your guitar to a drier climate, (either hot or cold), there is another danger. In areas of low humidity, the evaporation of moisture in the wood can cause shrinkage and cracking, no matter how long the wood may have been previo

13、usly aged. It also can cause the top and back to shrink, making the string action low. The collective experience of all of the major guitar manufacturers today, has demonstrated that the ideal temperature to preserve the integrity of solid wood acoustic guitars is room temperature, which is about 70

14、 F (20.5 C). The ideal humidity is about 40% to 50%. In the winter, the forced air systems used to heat most homes, can drive temperatures up and humidity levels dangerously low for guitars. A good measure of protection against drying out your guitar is to use a room humidifier. When the instrument

15、is not in use, we recommend that you keep it in its case and use one of the small guitar humidifiers such as “Dampit”, available from many instrument dealers. Do not leave the guitar out for long periods near a heating vent, radiator or in direct sunlight near a window. Do not leave your guitar in t

16、he trunk of a car for long periods and keep it away from excessive heat and cold. Please note: Damage caused to the guitar as the result of exposure to temperature or humidity changes will not be covered under the Gretsch warranty. Cracks in the Wood Cracks in the wood are typically caused by change

17、s in temperature and humidity. While a crack may initially be alarming, if it is taken care of promptly it shouldnt be a cause for undue concern. Cracks may easily be repaired without compromising structural or tonal integrity. If the crack is in the top, near the bridge, loosen all the strings to r

18、educe tension, (which could potentially exacerbate the problem), and have the crack repaired as soon as you can. Please note: Cracks in the wood, which occur as the result of exposure to temperature or humidity changes will not be covered under the Gretsch warranty. 23 Finish Checking Finish checkin

19、g, (very small splits in the finish), usually occurs in winter and is typically the result of suddenly exposing a cold instrument to the shock of warmer temperatures. All of the materials that make up a guitar expand and contract with changes in temperature and humidity, and they do this at differen

20、t rates. Wood expands as it warms, and it does so faster than the finish placed over it. When this expansion occurs, the finish does stretch somewhat, but when it cannot stretch anymore, it will split and fracture in little lines over the wood. Although it does not affect the tone of the instrument,

21、 this finish checking mars its appearance. By avoiding sudden temperature and humidity changes, you should not have any finish checking problems. When an instrument has been brought into a building after it has been out in the cold, allow plenty of time for it to become acclimated to the new tempera

22、ture before you open the case. Please note: Finish checks, which occur as the result of exposure to temperature or humidity changes will not be covered under the Gretsch warranty. General Maintenance Clean the instrument after each use, making sure to wipe the fingerboard and strings, as well as any

23、 of the plated parts, i.e. machine heads, pickups, etc. with a soft dry cloth. For gloss finishes, use a non-silicone based guitar polish. For satin finishes, use only a soft dry polishing cloth. For hand-rubbed finishes, use a soft, slightly damp cloth and follow with a dry cloth. When not playing

24、the instrument, keep it tuned to pitch and in its case. However, if you plan to store the instrument for long periods of time, loosen the strings a bit to relieve the tension, but do not remove them. The natural oils in Rosewood and Ebony fingerboards may dry out over time. Rough, exposed fret edges

25、 are evidence of dry, shrunken wood. It is a good idea to give your fretboard a drink of raw linseed oil periodically to preserve its integrity and natural beauty. Remove the strings first; then apply the oil to a clean lint free cloth. Rub into the wood, let it soak in, and then wipe to dry any exc

26、ess oil. Be careful when using vinyl, plastic or synthetic leather guitar straps, guitar stands and wall hangers using surgical rubber tubing, as these materials may react with, and mar the finish of your instrument. Please note: Damage caused to the instrument by the use of non-FMIC-approved polish

27、es, cleaning materials or accessories, will not be covered under the Gretsch warranty. Tuning Machines Gretsch uses only the finest tuning machines. Many of these machines are pre- lubricated, die-cast, sealed tuners, which do not require periodic oiling for smooth operation. A small tension adjustm

28、ent screw is located at the end of each die-cast tuners button (A), that also holds the button in place. If the tension is too loose, the machine may slip and go out of tune easily. If it is too tight, the button may become very difficult to turn. Make sure that the adjustment is firm, but not too t

29、ight. 45 Next, depress the “B” string at the 5th fret, to produce an “E” and tune the thinnest string to a matching “E”. Finally, go back and play the low “E” string and tune it until the pitch at the 5th fret, an “A”, matches the “A” on the adjacent string. If using an electronic tuner on your elec

30、tric or acoustic/electric, simply plug in your guitar, turn the volume up and tune from low strings to high as noted on the tuner: E, A, D, G, B, E. Tuning 12-String Guitars Due to the tremendous amount of tension exerted on the neck by the 12 strings, we suggest that you use a light gauge .010 to .

31、048 set on your 12-string guitar. In standard 12-string tuning, the second string in each pair is tuned to the same pitches, E, A, D, G, B, E, and using the same methods as the six string guitar on the previous page. For the E, A, D, and G strings, the first smaller string in each pair is tuned to t

32、he same note, but an octave higher in pitch than its partner. For the B and E strings, the first string in each pair is tuned in unison, (exactly the same pitch), as its partner string. Many players find it difficult to press the strings down on a 12-string, due to the high tension caused by the ext

33、ra strings. A remedy that some players choose is to tune the entire guitar to a lower relative pitch, such as E-flat or D; thereby reducing the string tension. You may then use a capo on the first or second fret, to bring it back up to where it plays at standard pitch. The guitar will certainly be e

34、asier to play, and the reduced tension will put less stress on the neck over time, but bear in mind that it will also sacrifice a bit of the tone projection of the instrument. All Gretsch 12-strings feature a truss rod system for superior strength and stability, however, a 12-string tuned at standar

35、d pitch, should be monitored regularly for For instruments with open gear tuners, make sure to lubricate the gear with a drop of lightweight oil from time to time for smooth operation. The Chrome and Gold plating on Gretsch tuning machines may become degraded from the acids and oils in finger sweat.

36、 Wipe the machines off with a soft dry cloth after each use to preserve their appearance and function. Strings that have not been secured properly to the tuning machine post may easily slip and go out of tune. This problem is commonly misdiagnosed as an issue with the tuners. Check your string insta

37、llation carefully. See illustrations 1, 2, and 3. Tuning 6-String Guitars There are a couple of different methods for tuning a guitar, depending on whether your guitar is acoustic, electric or an acoustic with a pickup. If you dont own an electronic chromatic tuner with a reference tone, you may wan

38、t to purchase one. It will dramatically simplify tuning your acoustic or electric guitar. Always tune from below pitch, up to the correct pitch instead of down from a higher pitch. This will help eliminate string slack from the tuning machine and decrease the possibility of slippage and tuning chang

39、es as you play. The strings should be tuned as follows, starting from the low (thickest) string, to the high (thinnest): E, A, D, G, B, E. If you have an acoustic guitar use the A- 440 reference tone on your tuner, a guitar pitch pipe, an A-440 tuning fork or other pitch reference, and tune the seco

40、nd string, “A” to pitch. Then, depress the second, or “A” string at the 5th fret, to produce a “D”, and tune the “D” string to that same pitch. Next, depress the D string at the 5th fret, to produce a “G”, and tune the “G” string until the pitches match. Next, depress the “G” string at the 4th fret,

41、 to produce a “B”, and tune the “B” string until the two pitches match. 45 the possible need of truss rod adjustments. A guitar in need of an adjustment that is ignored may develop permanent problems. (See page 14.) Please Note: Warpage of the neck, caused by the neglect of necessary adjustments wil

42、l not be covered under the Gretsch warranty. Changing Strings A fresh set of strings can breathe new life into your instrument. That is why many “tone-conscious” touring professionals change their strings before every performance. While there is no set rule on how often to change strings, we have fo

43、und that most players do not change them nearly as often as they should. Body oils, acids from sweaty hands and humidity all interact with the metals in guitar strings and cause a corrosion and breakdown of the materials. Dont wait until your strings break and fall off from old age before you change

44、 them. Worn, oxidized, pitted and dirty strings will not hold pitch, and simply sound bad. If you are an average player, playing several times a week, we suggest that you change the strings at least once a month. When changing strings, we recommend that you remove and replace each string one at a ti

45、me, instead of all at once. This will prevent sudden and potentially damaging changes in neck tension. Each new string should be tuned up to correct pitch before the next one is removed. When tuning a brand new string, always bring it up to pitch slowly. Otherwise, the rapid stretching may cause the

46、 string to break. Re-Stringing Your Guitar with a Fixed Tailpiece The procedure for re-stringing acoustic guitars, electric guitars and basses, is quite similar in the way the strings are wound onto the tuning machines. There are differences though, in how the strings are attached to the bridges of

47、acoustic and electric guitars. Gretsch flat-top acoustics have a pin style bridge with holes and bridge pins to hold the strings in place. The predominant setup for Gretsch electric guitars is the floating bridge paired with the Bigsby Vibrato Tailpiece. There are also some acoustics and electrics t

48、hat have fixed tailpieces through which the strings are fed. To string a flat-top, remove the bridge pin and the old string, drop the ball end of the new string into the hole in the bridge, then re-insert the bridge pin to keep the string in place. Make sure that the bridge pin is positioned with th

49、e groove over the string. Do not hammer the bridge pin in. A firm push with the thumb will secure it in place. To string an electric with a surface mounted bridge and fixed tailpiece, simply feed the string through the appropriate hole in the bridge or slot in the tailpiece. To attach a string to the machine head, thread it through the hole or slot on the machine head, running it halfway around the post, then underneath the main length of the string. Next, pull the string end back over the
