The Conn ST-21 Strobotuner is a legendary, vintage electromechanical strobe tuner from the 1970s. It operates on the stroboscopic effect to provide hyper-accurate, real-time frequency analysis, making it an industry standard for tuning pianos, organs, and setting guitar intonation.
Key Features
- Extreme Accuracy: Unlike digital tuners, analog strobe tuners project light through a spinning plastic disc to provide zero-latency pitch detection.
- Calibration: It allows for manual pitch calibration to fine-tune standard reference pitches.
- Input Options: It features a direct 1/4" instrument input as well as an external microphone (typically dynamic) to capture acoustic instruments.
- Designed by the renowned brand Conn in the United States, this model is suitable for musicians looking for a high-quality tuning tool. Includes original manual and a mic.
