AROMA AT-01A Colorful Clip-on Tuner is a compact, multi-instrument tuner that supports chromatic, guitar, bass, ukulele, and violin tuning. With a single button, tuning becomes quick and intuitive, ideal for practice sessions, quick song changes, or on‑stage adjustments. The LCD display features two-color backlight—green when in tune, white when out of tune—so you always know your pitch at a glance.

Rotatable design provides flexible viewing angles, allowing you to read the display from multiple positions whether you’re playing seated, standing, or at a mic. It helps you lock in accurate tuning across the standard 440 Hz pitch with ±0.5 cent precision, delivering reliable tuning for precise performances.

Model AT-01A ships in six vibrant colors—Yellow, Blue, Purple, Pink, White, and Green—so you can match your gear or style. Powered by a CR2032 battery (not included), this tuner weighs just 18.5 g (0.7 oz), making it unobtrusive during practice or performances. Package size is compact (5.5 × 4.5 × 3.5 cm) with a package weight of 30 g.
