Korg At2 ((link)) May 2026

If you find a Korg AT2 at a garage sale, a pawn shop, or a vintage gear auction, buy it. It is the tuner for the obsessive, the professional, and the curious. It is the bridge between the mathematical purity of a strobe tuner and the practical convenience of a chromatic clip-on.

However, the AT-1 had one major limitation: it was designed primarily for tempered tuning (standard 12-tone equal temperament). As music became more sophisticated, and as interest in just intonation, pure thirds, and vintage synthesis grew, Korg realized they needed an upgrade. korg at2

For a studio engineer who has to tune a piano that was last serviced in 1965, being able to match the AT2 to the piano's current pitch (say, 435 Hz) before adjusting the strings is invaluable. This feature, combined with the user temperaments, makes the AT2 a de-facto tool for piano technicians and harpists. At the time of its release, the AT2 faced competition from the Peterson StroboStomp (guitar pedal) and the Boss TU-series. If you find a Korg AT2 at a

In the world of live performance and studio recording, the humble tuner is often overlooked. We plug in, we glance at a needle or a row of LEDs, we turn a peg, and we move on. For decades, this process was simply a utility—a necessary chore. However, every so often, a product comes along that transforms a utility into an instrument in its own right. The Korg AT2 is precisely that device. However, the AT-1 had one major limitation: it

This article dives deep into the history, technology, ergonomics, and practical application of the Korg AT2, explaining why, years after its release, it remains a gold standard for musicians who refuse to compromise. To understand the AT2, you must understand its predecessor. When Korg released the AT-1 (Auto Tuner), it shocked the market. Before the AT-1, most tuners used a mechanical VU meter needle. The AT-1 replaced that with a 61-segment LED matrix. Suddenly, musicians could see their pitch stability in real-time, as a "moving dot" traveling across a high-resolution screen. It was fast, visible in the dark, and incredibly accurate.
