About Tronical

Throughout their 31-year history, automatic guitar tuners have remained stubbornly complex systems that cost thousands of dollars and require tedious professional installation. Christopher Adams, CEO of Tronical in Hamburg, Germany, has figured out a way around these problems. Using an off-the-shelf microprocessor, custom tuning algorithms, and six lightweight motors, Adams developed the first system that musicians can retrofit onto nearly any guitar’s headstock—without any wiring, drilling, or soldering. Once attached,  TronicalTune can make an instrument pitch-perfect in about five seconds. The revolutionary device is for electric and acoustic guitars alike that seamlessly self-tunes your guitar in a matter of seconds, all the while preserving the integrity and tone of your instrument. Suitable for various guitar models (currently over 1000) – selection by template system.

With no modification to the instrument at all. The system consists of a miniaturized micro-controller and six motorized tuning pegs, which insert onto the back of the headstock replacing the existing machine heads. It allows the user to access up to 36 different tunings at the touch of a button.

After selecting from 36 presets (e.g., standard, open E), a user strums all six strings at once. A piezoelectric sensor picks up the vibrations, and a processor separates out the tones of each string. When it detects an off-pitch note, it signals the servomotor in the peg to turn, tightening or loosening the string to adjust the pitch. Once all six strings are tuned, the system turns itself off.


Different guitar bodies and strings create slight variations in timbre, so Adams programmed the TronicalTune to grow accustomed to a guitar over the course of 10 to 20 tunings. The processor tracks the overtones and adjusts its tuning accordingly.


Tronical is the market leader as well as technological pioneer in the range of self-tuning systems for musical instruments. Our business culture is affected by consistent exceeding of limitations to achieve excellent solutions for our products. All necessary core competencies and devices are provided at one spot. That ensures a prompt and well coordinated product development.
