The
AutoStrobe 490-ST includes stretch tuning capabilities for enhanced tuning of
stringed or percussive instruments such as the piano, bass, guitar, marimba,
steel pan, and others. Only Peterson strobe tuners respond at the speed of light
to display relative tuning of any audio source to 0.1 of a cent (1/1000 of a
semitone) accuracy. With the new AutoStrobe models such as the 490-ST, students,
technicians, and musicians at all levels can utilize automatic (hands-free) note
selection for fast, accurate tuning of instruments. This feature also permits
real-time display of intonation to improve performance and listening skills
while playing.
