Peterson AutoStrobe 490 Strobe Tuner

Professional Strobe Tuner for Precise and Accurate Instrument Tuning
The Peterson AutoStrobe 490 is a high-precision strobe tuner designed for musicians, educators, and technicians who require the highest level of tuning accuracy. Unlike standard electronic tuners, the 490 responds instantly, delivering real-time tuning feedback with an ultra-fine resolution of 0.1 cent (1/1000 of a semitone). This ensures that every instrument—whether strings, brass, woodwinds, or percussion—is tuned with exceptional precision.

Hands-Free Automatic Note Selection for Seamless Tuning
Featuring automatic note selection, the AutoStrobe 490 eliminates the need for manual adjustments while tuning. Simply play a note, and the tuner instantly detects and displays the correct pitch, making the process faster and more efficient. This hands-free operation is ideal for musicians who need quick, reliable tuning during performances, practice sessions, or instrument maintenance.

Optimized Display for Enhanced Visibility Across All Registers
The Peterson 490 is designed with an advanced display system that enhances clarity for both upper and lower register notes. Its unique +2/-1 display function shifts strobe patterns into a more visible range, allowing bass note patterns to be displayed two octaves higher and treble note patterns one octave lower. This feature ensures that musicians can see tuning details with exceptional clarity, even in challenging lighting conditions.

Transposition and Custom Temperament Features for Versatile Use
Designed to accommodate a wide variety of musical instruments, the AutoStrobe 490 includes an easy transposition function. Strobe patterns automatically adjust for instruments in Bb, F, and Eb keys, making it a perfect choice for brass and woodwind players. Additionally, built-in and programmable temperaments allow for customized tuning systems, making this tuner an essential tool for historical performance ensembles, keyboard tuners, and specialized musicians.

Silent Tuning with External Input and Through Output
For live performances and recording applications, the AutoStrobe 490 offers an external input and through-output with mute functionality. This allows musicians to silently tune their instruments without disrupting a performance or rehearsal. The external input ensures accurate pitch detection, while the through-output lets users keep their instrument connected to an amplifier or effects chain without signal interference.

Durable Design with Expandable Accessories for Every Setup
Constructed with Peterson’s industry-leading reliability, the 490 is built to withstand regular use in studios, classrooms, and professional settings. Additional accessories such as external microphones, footswitches, and carrying cases are available to customize the tuner to fit specific needs, ensuring a long-lasting and adaptable solution for all musicians.
