The B, E, A, D and G LEDs indicate which strings you
are currently tuning. When the D and G LEDs are lit,
you are tuning the C string. The string is in perfect tune
when both green LEDs to the right of the string LEDs
are lit.
The tuner is always active.
9. USB port
To transfer a downloaded TonePrint from your comput-

TC device using a USB cable. A USB connection can
also be used to update the internal software (firmware)
of the TC device.
10. MUTE button
To tune you instrument silently, press the MUTE but-
ton. This will mute all signal paths (the bass combo’s
internal speaker, the PHONES and the BALANCED
OUTPUT).
When you have connected a Switch-3 to the PEDAL
jack (see section 7), you can tap its third switch to mute
or unmute. Switch-3 overrides the Mute button on
the bass combo.
11. AUX IN
The AUX IN is a stereo auxiliary input. Any signal pres-
ent on the AUX IN jack is played back through the out-
put of your bass combo. This allows you to play along
with a rehearsal track, or you can practice to the beat
of a metronome click. The included “mini jack to mini
jack cable” allows you to use an iPod®, iPhone® or
any other consumer playback device as a source for
rehearsing.

The PHONES jack is a 1/8” connector for headphones.
With a mild speaker filter applied to the bass sound, our
studio quality headphone amp caters for a great head-
phone sound. The headphone output also plays back
any signal connected to the AUX IN input jack. This
feature allows you to play along with an audio player, a
signal from a computer or any other audio source play-
