Guided Tour

While playing your guitar, bring up the level on your guitar and adjust the
INPUT LEVEL control on the rear panel of the GW10. Increase the level
slowly as you play the guitar while looking at the INPUT PEAK LED on
the panel. When you play your guitar the loudest, the indicator should
light intermittently.

Next, slowly bring the volume up with the Foot Controller on the GW10.

Now that you've properly set the level on the GW10, slowly bring up the
other volume controls to suitable levels — starting with the amp.
If you've followed all these instructions carefully, you should now be able
to hear your guitar sound processed by the effects of the GW10.
