Born from the rigor required by artisanal harpsichord making and the maintenance of historical instruments, Beaupré Tuner puts ultra-high acoustic precision within reach of all musicians. Whether you play the guitar, organ, violin, trumpet, clarinet, harpsichord, piano, or timpani, the intonation of your instrument and the beauty of your tone should never be compromised.

You now have in your pocket the only tool needed to maintain your instruments and an advanced analysis console to refine your sound according to your repertoire.
