2. Introduction
As the world’s first polyphonic tuner, the original POLYTUNE took the hear ts
of guitarists by storm. Features such as the MonoPoly technology (which
automatically detects whether you want to tune a single string or all strings)
made tuning a bass or guitar faster and easier than ever before.
2.2 Setting up
Connect a 9 V power supply with the following symbol to the DC input socket of
your TC ELECTRONIC effect pedal.
This product does not come with a power supply. We recommend using
TC ELECTRONIC’s PowerPlug 9 (sold separately).
• You can also power POLYTUNE 3 using a standard 9V battery (not included),
but if you intend to power additional pedals using the power out jack, you
need to use a power supply. Plug the power supply into a power outlet.
• Plug the power supply into a power outlet.
• Connect your instrument to the in jack on the right side of the pedal using a
¼" jack cable.
• Connect the out jack on the left side of the pedal to your amplier using a
¼" jack cable.
• If you have another 9 V guitar pedal that you want to power, connect it to the
power out socket on the rear of the pedal.
2.3 Get ready for a new tuning experience!
Tuning your instrument with POLYTUNE 3 is fast and intuitive. If you don’t feel
like reading the manual, just strum your instrument and watch the display.
We think you’ll like what you see.
So how do you make the best-selling polyphonic tuner even better? You take
it to the next level by: providing multiple tuning modes, including polyphonic,
chromatic, strobe and a variety of altered tunings; adding an onboard BONAFIDE
BUFFER to preserve your tone over long cable runs and pedal board signal paths;
and upgrading the LED display for even higher tuning accuracy.
Enter POLYTUNE 3.
2.1 Unpacking
Your TC ELECTRONIC effect pedal box should contain the following items:
• Your TC ELECTRONIC eect pedal
• 1 TC ELECTRONIC sticker
• 1 Quick Start Guide for quick information about the pedal’s controls
Inspect all items for signs of transit damage. In the unlikely event of transit
damage, inform the carrier and supplier.
If damage has occurred, keep all packaging, as it can be used as evidence of
excessive handling force.
