ZOOM GFX-707

Preparations
1 Use a monaural cable to connect the guitar
to the INPUT jack of the GFX-707.
At this time, the amplifier power switch and the
power switch of the GFX-707 should be OFF.
2 Use a monaural cable to connect the
OUTPUT jack of the GFX-707 to the input
of the amplifier.
By using two amplifiers, you can get great
stereo sound from stereo effects. Use a stereo
Y cable to connect the OUTPUT jack to the
two amplifiers.
3 To monitor the sound with headphones,
connect the headphones to the OUTPUT
jack.
4 Verify that the amplifier is turned off and
that the volume control is turned to
minimum. Also verify that the power switch
of the GFX-707 is set to OFF.
5 When using an AC adapter, plug the output
cable from the adapter into the DC 9V jack
on the GFX-707 and plug the adapter into
an AC outlet.
To guard against inadvertently disconnecting
the AC adapter cable, wind the cable once
around the hook on the rear panel of the GFX-
707.
6 Turn on power in the order GFX-707 →
amplifier (playback equipment).
7 Adjust the volume of the amplifier and the
GFX-707 to a suitable position while
playing the instrument.
The OUTPUT knob of the GFX-707 should be
set to about the 3 o'clock position, and the AMP
SIM knob should be set to the OFF position.
When the GFX-707 is in the bypass state (all
effects are temporarily turned off; see page
10), the output level will be the same as the
input level if the OUTPUT knob is turned fully
clockwise.
