Korg — At2 Top
This device is niche by design. It is not for the casual pianist or the producer working strictly in a DAW. It is built for the live performing arranger player.
If you are a solo entertainer using a Korg Pa series keyboard to manage backing tracks, vocals, and live keys, the AT-2 Top is arguably an essential upgrade. It preserves the professional look of your rig and offers the reliability Korg is known for. However, for those using different keyboard brands or strictly studio setups, the AT-2 offers little utility, as it relies on the physical architecture of specific Korg models for mounting and power.
Setting intonation requires seeing the needle stop moving. The Top mode offers a "Strobe" simulation that rolls so slowly, you can see the pitch drift over 10 seconds. This allows micro-adjustments to the saddle that generic tuners miss.
| Model | Accuracy | Auto Mode | Polyphonic | Strobe | Price (approx.) | |-------|----------|-----------|------------|--------|------------------| | Korg AT-2 | ±1 cent | Yes | No | No | $25–35 | | Korg Sledgehammer Pro | ±0.1 cent | Yes | No | Yes | $50–60 | | TC Electronic PolyTune 3 | ±0.5 cent | Yes | Yes | No | $80–100 | korg at2 top
The standard Korg AT2 is great. The Korg AT2 Top is superior for acoustic instruments. The secret is the CM-300 contact microphone.
In loud environments, a standard built-in mic picks up ambient noise—the drummer in the next room, the HVAC system, or the singer warming up. The contact microphone solves this by picking up physical vibrations directly from the body of the instrument.
Use cases for the CM-300:
Without the contact mic, you only have 50% of the machine. With it, the Korg AT2 Top becomes the most versatile tuner under $100.
In the world of clip-on tuners, precision is paramount, but durability and display quality run a close second. For decades, Korg has been the gold standard. When musicians search for the Korg AT2 Top, they aren’t just looking for a tuning device; they are looking for the definitive version of the legendary AW-LT2 platform.
The "AT2" (often referred to in shorthand for the AW-AT2 model range) and specifically the "Top" variants (referring to the high-brightness LCD and often the specialized "AT2-BK" or "AT2-CL" high-end clips) represent a leap forward. But does it live up to the hype? This device is niche by design
Let’s break down why the Korg AT2 Top might be the last clip-on tuner you ever buy.
The AT2 detects from C1 (32.70 Hz) to C8 (4186.01 Hz) . This covers the low B on a 5-string bass all the way up to the highest harmonics of a piccolo.
The Korg AT2 Top is a compact analog-style tabletop drum machine and groove box designed for beat production, live performance, and studio sketching. It blends classic drum-machine workflow with modern connectivity and hands-on sequencing. Without the contact mic, you only have 50% of the machine
