**Functioning**

The Conn ST-11 Strobotuner is a high-accuracy electronic tuning device designed for precise pitch detection on a wide range of instruments, from guitars and basses to pianos, organs, and band/orchestra instruments E. It is a solid-state, digital model built with modern integrated circuits and transistors, eliminating the need for vacuum tubes and offering long-term stability and reliability.

Key Features

• High-accuracy strobe tuning mechanism using the stroboscopic effect to visually indicate pitch accuracy.
• Accuracy within one cent (1/100th of a semitone) due to sophisticated circuitry.
• Bright display for clear visual feedback in various lighting conditions.
• Durable construction with a metal case, built to withstand regular professional use.
• Intuitive interface for quick tuning adjustments.
• Transposing instrument support and extended range piano tuning capabilities.
• Piano and organ tuning features, including range charts and temperament settings.
• Calibration before use recommended for optimal performance.
