The Korg GA Custom is the company’s latest upgrade to its GA line of pocket-sized tuners, offering improved detection accuracy and Korg’s eye-catching 3D Visual display — all for a modest price.
Korg’s GA-1 is a basic, inexpensive and pocket-sized tuner specially designed for guitar and bass. It’s a great, sturdy, no-frills tuner well-suited to beginners.
The GA-40 has been a staple of Korg’s tuner line-up since 2005. It’s a basic, inexpensive and rugged little unit with a few nice-to-have extra features. Intended for use with guitar and bass only.
The GripTune is one of our favorite clip-ons for guitar. It’s incredibly small and lightweight, fits almost invisibly on your headstock, and provides respectable ±1.0 cent detection accuracy.
Korg’s Headtune is a simple, robust clip-on intended for beginners. It’s available in guitar, bass and ukulele variations.
The Magnetune is a small, lightweight and super-simple tuner especially for guitarists. It attaches to your guitar’s strap button or tuning peg enclosure by means of a magnet embedded in the tuner.
The stalwart Pitchblack has served as the basic pedal tuner offering in Korg’s line-up since 2007. And while still a solid choice, the Pitchblack Advance now provides much better accuracy and improved features at about the same price.
Korg’s Pitchblack Plus is underrated gem of a tuner. In addition to its excellent ±0.1 cent accuracy and wide range of tuning options, this tuner offers dual input jacks with each jack accommodating separate tuning settings. Now discontinued, you can often find good deals for the Plus on Reverb.
Korg’s newest guitar tuner, issued in late 2016, features very good ±0.1 cent accuracy and a new circuit designed to reduce signal noise when the pedal is connected to a power supply cable.
