Adjusting the Action
Adjusting the action (string height) is very easy. Simply lift the string off the saddle and use your nail, a guitar pick, or a screwdriver, to turn the saddle. Note that if you have Rev 5 hardware, you need to loosen the small set screw that secures the saddle. See the video above for more information.
Turning it a half turn changes the action by 0.25 mm (0.01″). Turn it counter-clockwise to raise the action and clockwise to lower the action. If you have Rev 5 hardware, you need to very carefully tighten the small set screw that secures the saddle. See the video above for more information.
If you change the gauge of string, or adjust the string height, you may need to also adjust the intonation for the guitar to play in tune across all registers.
To check the intonation, compare the harmonic on the 12th fret to the fretted note. In this case, the fretted note is higher than the harmonic.
If the fretted note is too high, it means that the distance between the 12th fret and the bridge is too short, so we need to move the bridge backwards. Conversely, if the fretted note was lower than the harmonic, the distance is too long, and the bridge needs to move forward.
After loosening the string, use the 2 mm Allen key to loosen the screw that holds the tuner in place. Always use the short end of the key to loosen or tighten the screws on the bridge and string lock. Move the bridge backwards or forwards as appropriate and lock it in place, tune the string back up to pitch and check the 12th fret harmonic vs. the fretted note again.
Your .strandberg* guitar neck is reinforced with carbon fiber for a perfect balance between stability and playability. Different playing styles require different relief, so we don’t want to make a completely stiff neck, but incorporate a dual-action truss rod for adjustment.
If you travel through different climate zones or the humidity changes drastically between seasons, you may have to adjust the relief.
To check the relief, fret the same string on the 1st and 24th fret.
Use your thumb to press the string against the 12th fret and check the distance. Most people are comfortable with a relief about the thickness of a business card – 0.25 mm (0.01″) with fairly low action, 1.5 mm (0.04″), but some players prefer a completely straight neck and considerably higher action. As a guide: if the strings rattle when you play the lower frets, you have too little relief and need to loosen the truss rod. If the strings rattle when you play the higher frets, you have too much relief and you need to tighten the truss rod.
The truss rod needs a 4 mm Allen key to be adjusted. NEVER turn more than 1/4 turn between checking the result. If you feel that you have to use a lot of force to turn it, take it to someone with experience rather than risk damaging it. Replacing a broken truss rod is a significant job!
