All Mitchell guitar models feature dual-action adjustable truss rods. The truss rod allows you to adjust the neck to counter the tension caused by the strings. The truss rod may need to be adjusted if you change string gauges, or if you lower or raise your standard tuning pitch below A440. String tension changes may also cause fret buzz.
How To Adjust The Truss Rod
Remove the truss rod cover and locate the truss rod nut.
Place a 4mm hex wrench and adjust as follows:
Clockwise tightens the truss rod, causing an convex bow. Too much may result in fret buzz and dead frets.
Counterclockwise loosens the truss rod, causing a concave bow. Too much may result in high-action and poor intonation.
Truss rod tension can be measured by using a capo at the first fret and holding the strings down where the neck joins the body (14th fret). There should be .3 mm to .5 mm of clearance at the 8th fret.
