Precision tuner for tuning and intonation
Don't just tune – check intonation and instrument setup
A correctly tuned open string doesn't guarantee clean intonation across the entire fretboard.
TUNE-O-MATIC combines precise chromatic pitch detection with fixed guitar tunings like Standard Tuning, Drop D, DADGAD, and Low C. The manual pitch lock holds a selected reference note and makes even tiny deviations clearly visible.
This makes TUNE-O-MATIC suitable not only for quick tuning, but also for checking intonation, alternative tunings, and targeted work on instrument setups.
For ambitious guitarists, musicians, teachers, and technicians who aren't satisfied with a rough "close enough" display.
See how precisely tuning and intonation are controlled
In the video, you can see TUNE-O-MATIC in practical use. The chromatic mode automatically detects the note played, while the fixed tuning modes guide you specifically through Standard Tuning, Drop D, DADGAD, Low C, and other guitar tunings.
The manual pitch lock is particularly important for instrument setup and intonation checks. The selected reference note remains fixed, allowing small deviations to be clearly assessed – for example, when comparing harmonics and fretted notes at the 12th fret.
This turns an ordinary tuner into a precise control tool for tuning, intonation, and alternative tunings.

Chromatic Mode: Analyze pitch precisely
In chromatic mode, TUNE-O-MATIC automatically detects the note played and shows the deviation from exact tuning in high resolution.
This makes the mode suitable not only for tuning open strings, but also for targeted checks of individual notes on the fretboard. You can check how much finger pressure, string action, or specific positions affect the actual pitch.
Especially in studio recordings, instrument setups, and critical chord voicings, small deviations become audible that a simple tuner often rates as "sufficiently tuned."
Chromatic mode doesn't just show the right note, but how precisely you're actually hitting it.
Fixed Mode: Set alternative tunings reproducibly
In Fixed Mode, you select a defined guitar tuning like Drop D, DADGAD, or Low C. TUNE-O-MATIC shows you the intended target note for each string and prevents you from accidentally landing in the wrong pitch range.
This is especially practical if you regularly switch between different tunings or prepare multiple instruments for different songs. Instead of having to check every tuning by heart, you get a clear and reproducible workflow.
Whether in lessons, the studio, or on stage, Fixed Mode ensures that alternative tunings can be set up quickly and reliably.
Don't just tune differently – establish every tuning in a controlled and repeatable way.
XXL Mode: Precise display from any working position
In XXL Mode, TUNE-O-MATIC enlarges the crucial information regarding pitch and deviation. This ensures the display remains clearly readable even when you're not sitting directly in front of the screen.
This is particularly helpful during instrument setups, at the workbench, in the studio, or in lessons. You can work on tuners, bridge saddles, or playing positions and still clearly follow the tuner's response.
Especially when adjusting intonation, the large display facilitates repeated comparisons between the reference note and the fretted note without having to constantly change your position relative to the screen.
This makes TUNE-O-MATIC an easy-to-read precision tool for tuning, intonation, and guitar setup.
Tune standard and open tunings precisely and reproducibly
TUNE-O-MATIC helps you quickly switch between standard tuning and alternative guitar tunings like Drop D, DADGAD, or Low C.
The fixed tuning modes show the correct target note for each string and ensure a clear, repeatable process – especially helpful with multiple instruments, studio sessions, lessons, or frequently changing song tunings.
The chromatic mode and manual pitch lock complement the fixed tunings with precise control of individual notes and instrument intonation.
Don't just get it roughly right; reproduce every tuning reliably.
Test chromatic pitch detection, fixed guitar tunings like Drop D and DADGAD, and the manual pitch lock for checking intonation directly with your own guitar.
