KORG AW-OTG / AW-OTB Tuner
All-new OLED display technology, revolutionary visibility and precision.
From 4K televisions to the latest smartphones and tablets, OLED screen technology is revered by the leaders of the tech industry for its superior visibility and appearance. Always the innovator, KORG is proud to declare a new chapter in the company’s rich tuner history with the AW-OTG & AW-OTB, the first ever tuners to incorporate OLED technology. These cutting-edge displays are clear, smooth and perfectly visible from any viewing angle. These new tuners provide class-leading precision and stunning visibility that will change the way players tune.

The guitar-specific AW-OTG features intuitive chord finder function
The guitar dedicated AW-OTG incorporates everything you would normally expect from a normal tuner, but also includes a chord finder function that’s incredibly useful for individual practice. This function will automatically display the chord being played, allowing you to visually follow and recognize any chord progression in real time.
Bass-specific AW-OTB has been optimized to tune lower notes with more speed & accuracy and includes a tempo finder function.
The bass-dedicated AW-OTB incorporates several functions that will delight bass players. For the first time ever, this tuner incorporates a tempo finder function, which shows the tempo at which the bass line is being played. This will be a welcomed addition for performing bass players who need to lock into the tempo.
Cutting edge OLED display technology provides an unprecedented degree of visibility
Revered for its gorgeous display, the latest OLED technology is widely used in the tech industry on the latest televisions and smartphones. Seeing an opportunity to elevate the tuner category, KORG has decided to incorporate this state-of-the-art technology into its latest tuner family. Clear, bright and easily seen from any angle, the OLED display will make even the slightest movement in pitch perfectly visible.
Astoundingly long battery life using only one AAA battery
One of the main focuses of the AW-OT series is reducing energy consumption. While offering the sharpest and most visible display available, it allows for 18 hours of continuous use. A battery icon will be displayed when the batteries are running low.
Firm and adjustable clip for maximum stability
The contact surface ratio of the clip has been increased to ensure high holding power. It will fit securely on a variety of guitar or bass headstocks with ease. The double mechanism of a movable arm and a ball joint simultaneously provides both free angle adjustment and durability. You can position the tuner to suit your preference.
