Peterson 490 Tuner
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 Model 490, 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.

NEW! EASY TRANSPOSITION - strobe patterns appear at the correct note for Bb, F, and Eb instruments.
NEW! EXTERNAL INPUT AND THROUGH OUTPUT WITH MUTE - for in-line, silent tuning during performances.
