Korg Handheld Digital Tuner
and Metronome in Black

Compact tuner and metronome with improved visibility, ear training tools and wide instrument support

Overview

The Korg Handheld Digital Tuner and Metronome is a compact all-in-one practice tool for players who need accurate tuning and reliable rhythm training in one easy-to-carry unit. Based on Korg’s TM-70T platform, it combines a high-precision tuner with a flexible metronome and allows both functions to be used at the same time. With an improved display, wide pitch detection range, transpose function, Sound Out and Sound Back modes, it is a practical choice for band, orchestra, guitar, ukulele, vocal and general music practice.

Features

The tuner section offers fast, accurate pitch detection across a wide C1 to C8 range, making it suitable for a broad variety of instruments. The LCD needle meter is designed for strong visibility and responsive pitch tracking, while adjustable calibration lets players match different concert pitch requirements from A4 = 410 Hz to 480 Hz.

The TM-70T is especially useful for wind and ensemble players thanks to its transpose function, which supports chromatic tuning as well as F, B-flat and E-flat settings. Marks for pure major and minor thirds help players refine ensemble intonation, and the Sound Out and Sound Back modes provide ear-training support by generating reference tones and helping players connect what they see on the meter with what they hear.

The metronome section covers a wide 30 to 252 bpm tempo range with pendulum step, full step and tap tempo settings. Fifteen rhythm variations give players useful options for building timing across different styles, while the clearer metronome, Sound Out and Sound Back audio helps the unit remain easy to hear during practice. A foldable stand, memory backup, auto power-off and long battery life make it convenient for daily use.
