Connect the instrument to be tuned to the INPUT jack, and connect the
eect pedal, amp, etc., to the OUTPUT jack.
Turn o the power of all devices before you make any connections to avoid
damaging your equipment.
The INPUT and OUTPUT jacks are mono. Stereo (TRS) cables will not work.
When using the internal mic for tuning, make sure nothing is connected
to the INPUT and OUTPUT jacks. The internal mic cannot be used when
a device is connected.

the pitch of an instrumental sound that contains large numbers of overtones
or a sound that has a rapid decay.
