The BOSS TU-3 Chromatic Tuner is a highly regarded and widely used pedal for guitarists and bassists. Known for its accuracy and reliability, it features a large, easy-to-read display and a wide range of tuning options. Here are the key features of the TU-3:

Features:

1. Large, Backlit LCD Display:

   • The display is large and backlit, making it easy to read in any lighting condition, from dim stages to bright daylight.

2. High Accuracy:

   • The TU-3 offers high-precision tuning with an accuracy of ±1 cent, ensuring that your instrument is tuned accurately.

3. Chromatic and Guitar/Bass Modes:

   • Chromatic Mode: Allows you to tune any note in the chromatic scale.

   • Guitar Mode: Simplifies tuning for standard guitar tuning (EADGBE).

   • Bass Mode: Simplifies tuning for standard bass tuning (EADG).

4. Flat Tuning:

   • The pedal supports flat tuning up to a half step (one fret) lower, which is useful for alternate tunings or when using heavier gauge strings.

5. Sound Out:

   • The TU-3 includes a built-in reference tone generator, which can be used to tune by ear. This is especially useful for acoustic instruments or when you need to tune in a noisy environment.
