8-octave Desktop Stroboscopic Tuner, with .1-cent Accuracy, Built-in Microphone, Mutable Throughputs, and 9 Factory (31 Programmable) Stretch-octave Tuning Modes
Tune Your Own Pianos and Percussion
With nine stretched-octave factory presets and 31 custom user profiles, the Peterson AutoStrobe 490ST makes it possible to tune uprights and concert grands to mallet instruments and electric pianos from the comfort of your own home. The AutoStrobe 490ST is one of the most powerful strobe tuners on the market, boasting an 8-octave range and accuracy within 1/1000 of a semitone (±0.1 cents). So whether you’re double-tracking guitars in the studio or tuning band instruments before a performance, the AutoStrobe 490ST has you covered for the most demanding tuning applications.
Stretched-octave tuning modes for pianos and percussion
Equal temperament tuning can have ill effects on smaller pianos due to a phenomenon called inharmonicity, in which the inflexibility of steel piano strings can cause higher-order harmonics to be sharp by as much as a perfect fifth. Stretched-octave tunings account for this by elongating the octaves (2.1:1, for example) to reduce beating between notes and produce an ear-pleasing sound. The AutoStrobe 490ST’s nine preset modes cover everything from spinets to concert grands, with 31 user-programmable stretch tunings to intonate reed and tine electric pianos, mallet percussion instruments, pan drums, and more.
Precision tuning for any Instrument
For studios, schools, and instrument technicians alike, the Peterson AutoStrobe 490ST desktop tuner is ready for any tuning task. This stroboscopic mechanical tuner displays both fundamentals and overtones. The innovative display automatically compensates for clear visibility over a wide range of pitch and volume, and improved clarity for upper- and lower-register notes. And it's easy to transpose for a wide variety of instruments including Bb, F, and Eb instruments. Factor in the built-in tuning presets featuring historic temperaments and sweetened tunings, and the Peterson AutoStrobe 490ST from Sweetwater comes highly equipped for any tuning application.
