Boss TU-3 Chromatic Tuner Pedal Bundle with Power and Cables

In this review the Boss TU-3 Chromatic Tuner Pedal Bundle is evaluated for gigging players and home studio users who need quick, accurate tuning plus pedalboard power. The reviewer finds the TU-3's core tuner excellent: the 21-segment LED meter with a High-Brightness mode makes it easy to read on dim stages or bright sunlight, and the Accu-Pitch sign gives a clear visual confirmation when a note is in tune. The bundled power supply and cables make this package a convenient all-in-one starter for players who want reliability straight out of the box.

Key Features

• 21-segment LED meter with brightness control: Provides precise visual feedback and stays visible in bright outdoor conditions when High-Brightness mode is engaged.
• Accu-Pitch Sign and accuracy: The Accu-Pitch sign verifies tuning completion and the tuner is accurate to +/- one cent for dependable pitch reference.
• Chromatic and Guitar/Bass modes: Lets guitarists and bassists tune by string number, with explicit support for 7-string guitars and 6-string basses for extended-range instruments.
• Mute while tuning: The tuner automatically mutes the output when engaged, so tuning is silent in a signal chain or onstage.
• Power for compact pedals: The included power supply can feed up to seven BOSS compact effect pedals, simplifying pedalboard setup.
• Complete bundle: Includes a power adapter, a premium 10-ft instrument cable, a 6-in patch cable, and a 3-pack of celluloid picks to get playing immediately.

Who It's For

The bundle is ideal for gigging musicians, rehearsal players, and home studio owners who want a reliable, bright, and accurate pedal tuner plus immediate utility from included cables and picks. The TU-3's clear display and mute function make it especially useful for stage use where silent, fast tuning matters.

Players who already own a full pedalboard power system or who need a battery-powered or compact pedal-only tuner might look elsewhere; this bundle is targeted at those who value a rugged pedal tuner plus a multi-output power supply and quality cables in one purchase.
