TC Electronic POLYTUNE 3 White Polyphonic Tuner Pedal with MASH Footswitch and Bonafide Buffer

The TC Electronic POLYTUNE 3 White stands apart from conventional tuner pedals by combining polyphonic tuning with a pressure-sensitive MASH footswitch, delivering both precision and expressive control in a compact, stage-ready format. Its switchable true bypass and Bonafide Buffer preserve your tone across any signal chain, while the bright LED display ensures visibility on dark stages.

Highlights

• Polyphonic tuning: strum all strings at once for instant feedback
• MASH footswitch: pressure-sensitive for momentary or latching operation
• Bonafide Buffer: switchable true bypass or buffered bypass to maintain signal integrity
• Strobe tuning mode with ±0.02 cent accuracy for ultra-precise intonation
• Bright LED display with ambient light sensor for clear visibility

In daily use

The POLYTUNE 3 White excels in both live and studio settings. Polyphonic mode lets you check tuning of all strings simultaneously, saving time between songs. For precise setups, switch to strobe mode and enjoy accuracy down to ±0.02 cent. The MASH footswitch responds to pressure, allowing you to engage the tuner with a light tap or hold for momentary tuning. When bypassed, the Bonafide Buffer prevents high-frequency loss over long cable runs, while true bypass mode offers a completely uncolored signal when disengaged.
