True Temperament Necks for S-Style Guitar
Tired of your guitar never QUITE playing in tune?
Every guitarist knows the truth: no matter how carefully you set intonation, tweak saddles, or bend notes into place, a traditional guitar neck will NEVER play perfectly in tune from one end to the other. Open strings may be spot-on, but play a D chord high up the neck and something always sounds sour. We all just learn to live with it—subtle bends, micro-adjustments, constant retuning—but the problem never really goes away.
True Temperament necks fix what no setup can
What if your guitar actually could play in tune everywhere? True Temperament necks finally address the fundamental flaw inherent in every conventional guitar. Their uniquely curved “squiggly” frets are engineered to match the precise speaking length of each string. The result is chords, octaves, and single notes that ring pure and perfectly in tune anywhere on the fretboard, in any key.
Why it works
Inventors Anders Thidell and Paul Guy spent years researching, field-testing, refining, and developing the Formula 1 True Temperament system. Each fret is individually calculated per string and position to eliminate the tiny pitch errors caused by traditional straight frets. The necks feel completely natural under your fingers, making the transition seamless. You play just like you always have, only now the entire guitar is in tune.
Hear your guitar in a new way
No more compensating, no more “close enough.” True Temperament necks deliver harmonically pure chords, accurate intonation for recording, and improved sustain without altering your playing technique. Legendary players like Steve Vai, John McLaughlin, and Steve Morse are already using this innovative system. And now, for the first time, these necks are available in North America exclusively from StewMac.
Stop fighting your guitar and start hearing it in tune.

About True Temperament
True Temperament is a proprietary fretting system designed to correct the inherent intonation flaws of traditional straight-fret guitars based on 12-tone equal temperament (12-TET). Conventional fret placement can’t fully compensate for string tension, action height, and inharmonicity, causing chords to sound slightly out of tune.
