Korg AW-LT100T Clip-on Tuner
The Korg AW-LT100T is a dedicated clip-on chromatic tuner designed specifically for trumpet, cornet, and trombone. It features a high-visibility colour LCD and a specialised small clip for attachment to the instrument bell, offering a significant battery life of up to 100 hours.

Overview
The Korg AW-LT100T is a specialised tuning device within Korg's portable accessories range. Unlike universal clip-on tuners that are often designed for flat headstocks, this model is engineered with a small, specific clip tailored for the thin metal edges of brass instrument bells. The unit prioritises ease of use during rehearsals and performances by providing a direct attachment that picks up vibrations through the instrument body.
Design and Ergonomics
A primary feature of the AW-LT100T is its highly adjustable physical interface. It utilises a double mechanism comprising a movable arm and a ball joint. This configuration allows the musician to position the display at virtually any angle, ensuring the LCD remains within the line of sight regardless of the player's posture or the specific orientation of the instrument bell. The display itself is a bright colour LCD, intended to remain legible under harsh stage lighting or in dim orchestral pits.

Power and Battery Life
Efficiency is a hallmark of this model, which operates on a single AAA battery. Korg specifies that the device can provide approximately 100 hours of continuous operation. This longevity is notably higher than many rechargeable or coin-cell alternatives, reducing the frequency of battery replacements for regular performers. It should be noted that the AAA battery is typically not included in the standard retail packaging.
Market Position and Comparisons
Positioned at a mid-range price point of approximately £36, the AW-LT100T serves a more niche audience than general-purpose tuners like the Korg GA-2 or the Korg GripTune. While guitarists might look toward the Behringer TU300 or the rechargeable Boss TU-05, brass players require the specific grip tension and mounting geometry provided by the AW-LT100T's small-format clip. It offers a more modern, integrated solution than traditional desktop tuners or purely mechanical timing aids like the Wittner W801 or the Gear4Music Mechanical Metronome.
