D'Addario Nexxus 360 Rechargeable Cello/Bass Tuner

Fast, stage-ready tuning for low strings—no batteries to replace

The D'Addario Nexxus 360 Cello/Bass Rechargeable Tuner is built for the realities of low-string tuning: quiet fundamentals, busy rehearsal rooms, and quick changes between pieces. Using a high-performance piezo pickup, it reads your instrument's vibrations instead of surrounding sound—so you can tune accurately even when the orchestra is warming up around you. This makes it a dependable clip-on tuner for cello and double bass players who need consistent results in lessons, rehearsals, and performance settings.

An extra-bright, full-color LED display with 360-degree adjustability stays easy to read from nearly any angle and in any lighting, whether you're in a classroom, rehearsal hall, or backstage. USB-C rechargeable power eliminates disposable batteries, and up to 24 hours of tuning time per charge keeps it ready for daily practice and frequent gigs. For best accuracy on cello or bass, attach the tuner to the side of the bridge near the lower strings for strong vibration transfer and clear response.
