User manual YAMAHA YPR20

[. . . ] Each machine has a tension adjustment screw, as illustrated. Clockwise rotation tightens the machine. The tuning machines should be adjusted to the extent that they are firm, but can turn smoothly. This adjustment is normally unnecessary, and excessive tightening can lead to premature tuning machine wear.

[. . . ] If the fretted tone is exactly the same pitch as the harmonic tone, no adjustments to the bridge saddles are necessary. However, if the fretted tone is higher in pitch (sharp) or lower in pitch (flat) than the harmonic tone, apply the appropriate adjustment as shown below. Repeat the same procedure for each string. If the fretted note is pitched higher than the harmonic, turn the corresponding saddle adjustment screw clockwise, increasing the active string length. Conversely, if the fretted note is pitched lower than the harmonic, turn the corresponding saddle adjustment screw counter-clockwise, reducing the active string length. When lower than harmonic When higher than harmonic 5 PICKUP HEIGHT ADJUSTMENT The height of the pickup (i. e. distance from the strings) affects gain -- the higher the pickup, the louder the sound, and vice versa. If the pickup is set too high, sustain and playability will suffer because of the magnetic pull on the strings. Adjust overall height using the screws located at either side of the pickup. The polepieces should normally be about 2 or 3 millimeters from the strings. Pickup adjustment screws If too much convex bend TRUSS ROD ADJUSTMENT The curvature of the neck should be slightly concave. Clockwise rotation of the nut tightens the rod and corrects for too much concave bow. Counterclockwise rotation of the nut loosens the rod and corrects for too much convex bend. · Broken guitar necks are mostly the result of accidents such as dropping the guitar, the guitar falling over, or from shocks occurred during transport. When the guitar is not being used, make sure it is kept on a sturdy stand where it won't fall over, or place it in its case. · Do not treat the instrument in a rough manner like throwing objects at the instrument, dropping the instrument, etc. And do not put excessive force on the switches or control knobs, etc. · When connecting or disconnecting the cable, make sure the guitar amplifier's power is switched OFF, or the amplifier's volume is turned all the way down. Not doing so can shorten the life of the guitar amplifier. · When cleaning the instrument, use a soft, dry cloth. Also, do not spray insecticides close to the instrument. Doing so can damage the guitar's finish. Store the Instrument Properly · Do not keep the instrument close to a fire or flame, and keep it on a low, stable surface. The instrument can catch fire, and earthquakes can cause it to fall if stored in a high location. · Do not leave the instrument leaning against the wall, etc. , in the vicinity of children.
