Korg GA-40 Guitar and Bass Tuner
Brand
KORG
Extended-range guitarists, multi-string bass players, and performing live musicians need a specialized tuning utility that locks onto extreme low frequencies instantly without meter bounce or delay. Basic multi-instrument tuners often lack the algorithmic depth to capture a low-B bass string, while fragile clip-ons force you to unplug your signal cable just to run a quick test between songs. The Korg GA-40 Dedicated Guitar and Bass Tuner addresses these exact performance problems. Re-engineered with an enlarged visual tracking screen, dedicated extended-string preset matrix, and a physical inline bypass output terminal, this pocket-sized utility serves as an indispensable daily setup anchor.
The KORG GA-40 Guitar & Bass Tuner is the definitive upgrade to Korg’s legendary GA-series, offering professional-grade tuning precision in a refined, user-friendly package. Building on the reliability that made the GA-30 a worldwide standard, the GA-40 adds a larger, more responsive LCD needle meter and enhanced pitch-detection algorithms, making it the perfect choice for guitarists and bassists who demand quick, accurate, and stable tuning for every practice and performance session.
Precision Detection and Ergonomic Design
At the heart of the GA-40 is Korg’s highly sensitive pitch-detection engine, which provides lightning-fast response times. Whether you are using a 7-string guitar or a 6-string bass, the tuner automatically recognizes the note and guides you to perfect pitch with its large, ultra-smooth needle display. The meter is designed to eliminate "jitter," providing a rock-solid visual reference that makes tuning effortless, even for beginners.
The GA-40 also features a dedicated "Flat" tuning mode, allowing you to drop-tune your instrument by up to five semitones without the need for manual recalibration. This makes it an invaluable utility for modern rock, metal, and blues players who frequently utilize down-tuned configurations. Combined with the "Sound Out" mode, which plays reference tones through the built-in speaker, it serves as both a high-performance tuner and an effective ear-training tool.
Built for the Working Musician
Designed with durability and battery life in mind, the GA-40 is incredibly efficient. A single pair of AAA batteries provides over 200 hours of continuous operation, ensuring that the tuner remains ready for long studio sessions or extensive touring schedules. Its slim, pocket-friendly design means it can be tucked into any instrument case or pedalboard storage, providing a reliable tuning backup that is always within reach.
