Peterson Model 490ST AutoStrobe Tuner with Stretch Tuning

Description

8-octave Desktop Stroboscopic Tuner, with .1-cent Accuracy, Built-in Microphone, Mutable Throughputs, and 9 Factory (31 Programmable) Stretch-octave Tuning Modes
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.
