Setup
T urning the power on/off
When using batteries:
1. Slide the battery cover (11) located on the underside of the case to ward the UNLOCK
position, and remov e it. Inser t two AA alkaline batteries (included), being sure to
observe the correct polarity . Close the co ver and slide it to the LOCK position to
f asten it in place.
2. When using batteries, the power will turn on when a
mono cable is plugged into the INPUT jac k (13). The
POWER LED (1) will light while the po wer is on.
The power will turn off when you remo ve the cab le
from the INPUT jack.
Be sure to remov e the cable from the INPUT jack when y ou are not using Ampworks
to preserve batter y lif e.
If you connect a stereo cab le, the power will not be turned on.
When the batteries run down, the POWER LED will b link. Replace the batter ies as
soon as possible. Batteries that ha ve become unusable should be remo ved from the
unit immediately . If dead batteries are left in the unit, the y may leak or cause other
malfunctions. Y ou should also remov e the batteries if you will not be using Ampworks
f or an extended period.
When using the AC adaptor:
1. Connect the separately sold A C adaptor to the DC 4.5V jack (12), and plug the A C
adaptor into an AC outlet. The PO WER LED (1) will light, and the power will turn on.
Use only the specified external A C adaptor. (DC 4.5V )
Be sure to disconnect the A C adaptor from the AC outlet when you are not using
Ampworks.
Connections
1.
T u rn off the power of the equipment y ou w ant to connect, and lower each v olume control.
2. Connect y our guitar to the INPUT jack (13).
3.
Set the LINE/AMP select s witch (14) to the appropriate position f or the output destination.
If you connect the output to a mix er , recorder, or headphones , use the "LINE" setting.
If you connect the output to a guitar amp , use the "AMP" position. When AMP is
selected, the cabinet response will automatically be adjusted internally to optimize the
sound produced through a guitar amp .
4. Connect the OUTPUT jack (15) to y our mixer or guitar amp .
The OUTPUT jack is stereo (TRS), so if y ou use a mono cable to connect it to your
guitar amp etc., only the sound of the L (left) channel will be heard.
If you are listening through headphones , connect them to this jack.
If you are running into two channels of a mix er or using two amplifiers in stereo , use a
stereo to dual mono cable .
5. If you w ant to use an external foot s witch to change user programs , manual settings or
bypass , connect the optional Korg PS-1 or PS-100 f oot switch to the FOO T SW jack
(16).
6. When you ha ve finished making connections , tur n on the pow er of the connected
equipment and adjust the volume .
Selec ting pr ograms (sounds)
Preset pro grams (11 programs)
1. Press the PRESET b utton (2) to light the LED .

User progr ams (PROG1, 2), Manual
1. Press the PR OG/MANU button (3). Each time you press the b utton you will cycle
through the follo wing three settings.
PROG1 (LED lit green): User-writable program 1
PROG2 (LED lit red): User-writable program 2
MANU AL (LED lit orange): The current settings of the knobs and selectors
Bypass
When you select Bypass , you will only hear the direct (unprocessed) sound of your
guitar . When Ampw orks is bypassed, the manual/program LED (PRESET or PR OG/
MANU) will go dark.
• T o bypass Ampworks , hold down the PROG/MANU button (3) f or about two seconds.
Press the PROG/MANU b utton once again to cancel bypass.
Crea ting your sound
T o create your o wn sound, you can either star t with an e xisting program and modify it, or
create a sound from scratch. If y ou star t with an existing prog ram, select the desired
program, and then use the control knobs (6) to adjust the amp settings , or adjust the
eff ect and effect depth. Y ou can also tr y changing the cabinet. Alternatively if y ou want to
create your sound from scr atch, you can use the method described below . At this time
you ma y wish to press the PROG/MANU b utton (3) to select MANUAL.
1. Use the AMP TYPE selector (4) to select one of the ele ven amp types.
2. Use the CABINET selector (5) to select one of the ele ven types of cabinet models.
The combination of amp type and cabinets will determine the basic tonal character of
the amp. An y cabinet model can be used with any amp model. Some recommended
combinations are in the "Eff ect parameter list." If you do not want to use eff ects, set
the EFF .DEPTH knob (8) to “0” (all the way to the left). ( )
