1
First, make sure that the power switch on the GW33
is off before making ANY connections.
2
Plug the DC output cable from the supplied PA-3
adaptor (or another adaptor recommended by
Yamaha) (Never use the PA-3B.) into the DC IN
terminal on the rear panel, then plug the adaptor into
a convenient AC outlet.
The cable clip located next to this terminal helps to
prevent accidental unplugging of the power supply
during use. Wrap the adaptor cord firmly around the
clip (see the Rear Panel illustration, page 10).
CAUTION!
■
Do not attempt to use a different
AC adaptor with the GW33. (See the precaution
USE THE CORRECT POWER SUPPLY
on page 3.)
3
Plug your instrument into the INPUT jack on the rear
panel.
For the sake of these instructions, we’ll assume
you’re using an electric guitar; however, most any
electronic instrument can be used.
NOTE
■
You should be careful if you are connecting
a synthesizer or electronic keyboard. Since their
output level is generally much higher than that of a
guitar, the volume control on the instrument should
be turned down accordingly.
4
Connect the GW33 output or outputs to your ampli-
fier/speaker system, as shown on page 10. Before
you do this, however, make sure that the power on
the system is first turned off and all volume controls
are set to zero — this includes the guitar controls and
the volume on the connected amp(s).
NOTE
■
Use the clean channel of the amplifier for
best results.
5
If you are using an optional FC7 Foot Controller
with the GW33, connect it to the FOOT CONTROL-
LER input jack on the rear panel. Make sure that the
pedal is at or near the maximum position.
6
Turn on the power of all the equipment, starting with
the GW33, and turning on the connected amplifier
last.
7
Before you turn up the volume and try to play, set all
the effects to off by using the Bypass function.
To do this, simultaneously press and hold down
Pedal Switches 2 and 3. Keep holding them down
(for roughly one second) until “
bP
” (Bypass)
appears in the BANK/MEMORY indicator.
This temporarily turns off all effect processing, and
lets you hear the “dry” input signal.
8
Now, set your guitar to a suitable volume. Next,
slowly bring up the level of the connected amplifier
as you play, until the level is suitable.
9
Finally, turn the Bypass function off by pressing any
one of the Pedal Switches (1 – 5 or B).
If you’ve followed all these instructions carefully,
you should now be able to hear the sound of your
guitar processed by the effects of the GW33, and are
able to try out some of the other effect programs of
the GW33. If no sound is output or the sound isn’t as
you expect, refer to the Troubleshooting section on
page 36.
