Introduction
The Korg AW-2+ Clip-On Chromatic Tuner is a legendary, highly adaptable tuning solution built to accommodate almost any acoustic or orchestral instrument on the planet. While many tuners limit you to a single clamp design, the AW-2+ arrives with an ingenious interchangeable dual-clip system, providing a perfect fit for everything from delicate violin pegboxes to large trombone bells. A massive favorite among Malaysian concert band players, orchestral musicians, and multi-instrumentalists, it offers unparalleled accuracy in both silent practice rooms and chaotic stage environments. Thanks to its selectable internal microphone and vibration-sensing piezo pickup, you can effortlessly tune up under any acoustic condition, ensuring your pitch is always perfect before the conductor raises the baton.
Main Features
The defining technical advantage of the Korg AW-2+ is its Dual-Sensor Tuning Architecture combined with an articulating Double Ball-Joint. Most clip-on tuners force you to rely solely on vibration, which can sometimes be tricky on uniquely shaped brass or woodwind bodies. The AW-2+ allows you to physically switch between a high-sensitivity piezo sensor (which detects structural vibrations, ignoring background noise) and a built-in internal microphone (perfect for acoustic instruments in quiet rooms). This sensor module is mounted on an incredibly flexible double ball-joint mechanism, granting you true 360-degree rotation and multi-angle positioning so the backlit screen is always perfectly in your line of sight.
Usage Scenarios
- The Noisy Rehearsal Hall: Switch the tuner to Piezo mode and clip it to your instrument to tune purely by physical vibration, completely ignoring the chaotic sound of fifty other musicians warming up around you.
- Transposing Horn Sections: Utilize the dedicated transpose button to instantly switch the tuner's readouts between C, E-flat, F, and B-flat, taking the mental math out of tuning transposing wind and brass instruments.
- Dark Orchestra Pits: The adjustable backlit LCD display features three brightness modes (Off, Soft, and Auto), ensuring you can check your intonation on dimly lit stages without distracting the audience.
- Classical String Performances: Swap to the smaller included clip to securely and safely attach the tuner to the narrower pegboxes of violins and violas without damaging the delicate wood finish.
- Acoustic Guitar Sessions: When practicing in a quiet room, switch to the internal microphone mode and clip it to your guitar headstock or use it on a music stand to capture the natural acoustic pitch from the air.
Features
- Interchangeable Dual Clips: Comes standard with two proprietary clips (large and small) to guarantee a secure, non-damaging fit on a massive variety of instrument shapes.
- Selectable Tuning Sensors: Easily toggle between a vibration-sensing Piezo pickup for loud environments and a highly sensitive internal microphone for quiet rooms.
- Smart Transpose Function: Quickly transpose the display pitch to C, E-flat, F, or B-flat, making it incredibly easy for brass and woodwind players to read their native notes.
- Double Ball-Joint Mechanism: Offers exceptional mobility and multi-angle positioning, allowing you to tilt and rotate the display exactly where you need it.
- Adjustable LCD Backlight: Features an energy-saving display with selectable Off, Soft, and Auto brightness modes to match your stage lighting perfectly.
- Pure Interval Markings: The display meter includes special visual indicators to help you accurately tune to pure major and minor third intervals for flawless section harmonies.
- Wide Chromatic Range: Tracks a massive pitch range from A0 to C8, making it suitable for everything from a contrabass to a piccolo.
- Energy-Saving Auto Power-Off: Automatically shuts down after periods of inactivity to drastically extend battery life up to 150 hours of continuous use.

CK Music Staff Recommendation
The Korg AW-2+ is a true classic that remains highly requested at CK Music for one major reason: the dual interchangeable clips. While most modern tuners just give you one generic, medium-sized clamp that inevitably slips off a thin violin pegbox or fails to open wide enough for a thick trombone bell, the AW-2+ solves this by giving you two dedicated sizes right out of the box. Add in the fact that you can actually switch between a piezo vibration sensor and a real internal microphone, and you have an incredibly versatile tool. Whether you are a Malaysian student jumping between different band instruments or a professional orchestral player needing pinpoint accuracy, this tuner simply adapts to whatever you throw at it.
