TC Electronic POLYTUNE 3 White Guitar Tuner Input Impedance 1000000 Ω

The TC Electronic POLYTUNE 3 White is a compact high‑precision guitar tuner designed for accurate and rapid tuning of electric and acoustic string instruments. With an input impedance of 1,000,000 Ω, multiple tuning modes (polyphonic, chromatic and strobe), an integrated BONAFIDE buffer to preserve tone through long cable runs, and a bright multi‑LED display with ambient light detection, POLYTUNE 3 suits stage and studio use where fast, reliable tuning and signal integrity are required.

Advantages

POLYTUNE 3 delivers fast polyphonic tuning as well as single‑string chromatic and strobe modes for higher precision. The high input impedance ensures accurate detection across pickups and active electronics, while the onboard BONAFIDE BUFFER prevents signal loss and maintains tone quality through pedalboards and long cables. The upgraded 109‑LED display with ambient light sensing provides clear readouts in varied lighting conditions, from daylight to dim stages.

Suitable for

• Live performance tuning where quick polyphonic checks are needed
• Studio tracking requiring high-precision strobe tuning
• Rehearsals and soundchecks for electric and acoustic guitars
• Pedalboard setups that require a buffer to preserve tone

Key specifications

• Input impedance: 1,000,000 Ω
• Tuning modes: polyphonic, chromatic, strobe
• Display: 109 bright LEDs with ambient light detection
• Onboard buffer: BONAFIDE BUFFER for signal integrity
• Form factor: compact pedal enclosure suitable for pedalboards

How to use

Connect your instrument to the input and the output to your amp or pedal chain, then select the desired tuning mode. For quick tuning on stage, strum all strings and use the polyphonic mode to see pitch status for each string simultaneously. For higher accuracy, switch to chromatic or strobe mode and pluck individual strings while observing the LED display. The BONAFIDE BUFFER remains active to keep tone consistent while the tuner is engaged.

Usage recommendations

For best results, place POLYTUNE 3 at the beginning of your pedalboard signal chain so the buffer can preserve your instrument’s tone. Use polyphonic mode for fast checks between songs and chromatic or strobe modes for final tuning during recording sessions. Adjust your playing volume slightly when using chromatic or strobe modes to ensure the tuner receives a clean signal for the most accurate readout.
