Quick Start
Set all controls to the 12:00 position and the volume at “0”. Plug the AG-110H into appropriate
power and turn the power (rear panel) switch on. Turn your guitar’s volume to zero. Plug a
quality cord into the AG-110H’s ¼” input, turn the AG-110H volume control to “5” then slowly
advance your guitar’s volume.
Volume Control
Acoustic electric guitars can have several types of pick-ups, each with different levels of output
and tonal characteristics. With the volume control on the AG-110H set at “5”, your guitar’s
volume control should cover a normal range of adjustment.
Pre-Amp Gain Trim
If your guitar’s volume is very sensitive (your guitar may have an active pre-amp and EQ), you
can back off the pre-amp gain trim. If your guitar does not go loud enough (you may have a
piezo pick-up), increase the pre-amp gain trim. Do not set the gain higher than necessary.
Adjusting Pre-Amp Gain Trim
Use a very small slotted screwdriver inserted through the top panel circular opening labeled “pre-
amp”, CW rotation increases gain, CCW decreases gain. Set the gain so that the controls on your
guitar work over a normal range with the volume on the AG-110H set at 5-8.
If the pre-amp gain is too high, you may over-drive the pre-amp and cause distortion. If the gain
is too low, there may be excessive hiss and noise and not enough volume.
Feedback
Feedback is a common problem when an electric acoustic guitar is amplified. If you are playing
in a home setting and want a typical amount of natural amplification, the contour, tone controls
and physical amplifier placement will work together to minimize feedback while providing the
volume and tone you desire. If you play in a louder venue (with a band, etc.), the use of a “sound
hole plug” is often the only way to eliminate feedback. These are commonly available at good
music stores. The rotary diffuser aids feedback by constantly changing the resonant nodes of the
room/stage.
