Humidity, Temperature, and Storage

Your guitar is made of thin wood which is easily affected by temperature and humidity. This combination is the most important single part of your guitar's surroundings. I keep my workshop at a constant 45-55 percent humidity and 68 to74 degrees Fahrenheit. If either humidity or temperature get far away from these conditions, your guitar is in danger. A rapid change in temperature or exposure to cold can cause small cracks in the finish. These are lacquer checks. I 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 expand and swell. A gradual increase in humidity won't 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 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 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 cracks and open joints. Don't set your instrument next to a source of heat or hang it on a wall where it will dry out. 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 to room temperature while still in its case. This allows it come up 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 cause damage, as can the rubber or vinyl parts of a humidifier.  Using a console model evaporative humidifier for the house is a good idea.  I recommend storing your guitar in its case when not in use. Don't bother loosening the strings when putting your guitar away unless it won't be used again for several months. Constantly tightening and loosening strings quickly ruins their sound.

The hard shell case supports the neck and body of your guitar as evenly as possible. It's important that you don't let anything lie under the head (the tuning machine end), as this could damage the neck and body.

Repairs to your instrument should be performed by a skilled repair person.

Cleaning the Finish

The best way to clean your guitar is with a soft cloth. Your guitar is coated in the highest-grade finish available and is sensitive. Any type of solvent, especially those found in plastic, 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 a special guitar polish and a clean polishing cloth. I recommend 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.

Changing Strings

When changing the treble strings, singe a ball in the end (away from the guitar) and tie a half-hitch knot as I did.  A larger knot is necessary with carbon trebles.  The knot must be bigger than the hole in the bridge tie block.  This way the strings will not slip thru the bridge holes and whack the top when tuned to pitch.

This article explains how to use and maintain friction pegs that are properly fitted. If the pegs on your guitar have been jammed into the headstock and protrude 1/2” (13mm) or more, they are most likely in need of replacement. A competent guitar or violin repair person will ream out the peg holes and replace the pegs with a slightly larger diameter shaft and taper to fit the newly reamed holes. The pegs, when properly fitted will protrude about 3/8” (10MM) above the head.

Please note how the pegs feel on your new Lester DeVoe Guitar. There should be little or no sound as the pegs smoothly turn.

When pegs are properly doped and waxed, about 80% of the time, you should be able to tune with your left hand only, while your right hand is plucking the strings. There should be a slight pressure toward the peg head as you twist the peg to tune.

When a peg kicks back and slips, bring your right hand up, holding the guitar peg head for support, as you gently twist with enough pressure to make the peg stay.

If a peg won’t stay or makes much noise when turning, it is time to rub on a few strokes of peg compound and a little birthday candle wax. Sabicas always had a birthday candle in his guitar case! Generally, wax makes the pegs turn smoother and peg compound makes it stay. A combination of both seems necessary to fix most problems. Two or three strokes of compound and one or two strokes of wax is usually all that is needed. The compound and wax is applied to the portion of the peg shaft that is inside the peg head, so first, take off the string and remove the peg. The compound I use is called W.E. HILL, A composition for pegs which have ceased to run smoothly. It comes in a lipstick like tube.

Note how the strings are wound on each peg: outside on pegs 1 and 6; inside on pegs 2,3,4,5. This will line the strings up with the nut slots and keep the strings from touching each other.

When changing strings try to maintain a balance of tension on the neck. Change one string at a time or slack the strings little by little 6,1,5,2,4,3…6,1,5,2,4,3…etc., until they are all slack.

When putting on a new string, pull the string through the hole in the end of the peg, pulling out all the slack and lock the string under itself as the first winding comes on.

*IMPORTANT* ~ STRINGS ARE WOUND DOWN FROM THE HOLE IN THE PEG BUT NEVER ALLOWED TO THOUCH THE PEG HEAD! If you have too much slack in the string and too many windings on the peg, the string will touch the peg head and then act like the threads of a screw pulling the peg into the hole, jamming it and ruin the tapered hole! It takes a lot of words to describe something that is really easy and makes sense when you understand what is going on. I hope your alert observations will get you through this learning process and you will appreciate the simplicity and beauty of using friction pegs.
