5. SET INTONATION You can easily set your bass guitar's basic intonation. Plug into your tuner and tune a string to pitch using the 12th-fret harmonic. Then fret the string at the 12th fret and compare that pitch to the 12th-fret harmonic pitch. If the pitch of the harmonic and the pitch of the fretted note agree, the string is properly intonated and no adjustment is necessary. If the two pitches disagree, an adjustment must be made, using either a Phillips screwdriver or a hex wrench, depending on the bridge type. pitches read the same. It's a good idea to stretch and re-tune the string during the adjustment, as the movement of the saddle will affect the pitch. If the fretted note is flatter, (lower in pitch relative to the harmonic), the string must be shortened until both pitches agree. To do this, turn the saddle length adjustment screw counterclockwise, moving the saddle forward, until the harmonic and the fretted pitches read the same. Remember to stretch and re-tune the string. If the fretted note is sharper (higher in pitch relative to the harmonic), the string must be lengthened until both pitches agree. To do this, turn the saddle length adjustment screw clockwise, moving the saddle toward the back of the bridge, until the harmonic and the fretted 27
