Seiko's STX1N Clip-Style Chromatic Tuner attaches to your headstock and is able to be tilted 90 and rotate 360, making it viewable from any direction, something that is very helpful during a live performance. It offers two tuning modes, automatic or manual. There is also a one octave reference tone for tuning by ear. Other features of the STX1N include a selectable input method, vibration sensor, a tuning range of A0-C8, and a built-in microphone and vibration sensor.
