How to adjust the truss rod on an electric guitarSmall tweaks, righty-tighty — the rod turns with string tension on. Which way to turn Clockwise tightens. Alan Ratcliffe, our Guitar Doctor, puts it simply: righty-tighty, lefty-loosey 2. Tightening reduces neck relief (flattens a forward bow); loosening increases relief 1. Strings stay on. Unlike old advice, Alan never slackens the strings — the rod is built to counter string tension at pitch. If it won't turn under load, the nut is seized or damaged, not a normal condition 3. Cautious option. DaFiz slackens strings and does quarter-turns with no stress on the rod — the safer route if you're unsure 3. How to do it Check relief first. Fret the 1st and 15th frets, look at the 7th — you want a slight gap, about a piece of paper thick 4. Only adjust if relief is actually wrong; the rod sets relief, not action 7. Go slowly. Less than a quarter turn at a time, then retune and let the neck settle — wood can take minutes or days to respond 4. Once set, seasonal tweaks are usually just 1/8 to 1/4 turn 8. Listen for warnings. Alan Ratcliffe notes truss rods "tell you when they are in distress": if it needs serious force or screeches, stop — the nut is likely seized or stripped 8, 5. Can't find the nut? Some (like the Vintage V100) hide a black anodised hex nut under polish debris in the truss cavity — look closely 4. If in doubt, Alan's golden rule: if you're not comfortable, hand it to a luthier 1. His full setup guide is linked in the threads 2.
