AT1/2 is an up-to-date unit provided with distortion control knob that simultaneously controls sustain time, and also tone control. It produces a
wide variety of distortion sound from mellow to intense, hard distortion.
GAIN
This knob controls sustain time as well as
distortion depth. When turned clockwise ,
distortion becomes deeper and sustain time
longer. And, when turned counterclockwise,
distortion becomes weaker and sustain time
shorter.
TONE
This knob controls tone. When turned clockwise
highs are boosted to give crisp tone, and when
turned counterclockwise lows are boosted to
give soft tone.
LEVEL
This knob functions to compensate for the level
difference between Normal and Effect settings.
Turning clockwise increases volume of Effect
mode and counterclockwise, decreases.

INPUT
This input jack receives output from electric guitar and other electronic instruments
OUTPUT
This jack feeds signal to amplifier.
AC ADAPTOR JACK
AT2-DISTORTION operates both from self-contained battery (9V) and from AC line. Connect a AC Adaptor (DC9V)
to this jack, and the battery is disconnected from the circuit, guaranteeing stable longtime performance.
PEDAL SWITCH
This is a changeover switch for Normal or Effect. By use of True Bypass SWITCH, first in these kinds of small size
effect units, pop noise is perfectly eliminated and AT2-DISTORTION can be satisfactorily employed even in studio
recording.
CHECK LAMP
While pedal is trod down, this lamp lights if battery is normal. Thus this lamp lets you confirm the changeover
between Effect and Normal modes, and also battery state. If the indicator fails to light, replace the battery with a
new one.
SCREW
When replacing battery, loosen this screw to open the caw. Do no remove off the screw from the pedal. If you do,
be careful not to lose it.

CAUTIONS FOR REPLACING AND HANDLING BATTERY INPUT
REPLACING BATTERY
USE ONE 9-VOLT BATTERY.
1. Loosen the screw of pedal to open it and take out battery from its housing.
2. Replace the battery by a fresh one and put it into position.
3. Set coil spring onto the projection on the rear of the pedal and shut the cover (pedal). Finally, insert the screw
into the pedal guide and tighten it.
At this time, be careful not to catch the battery strap in the cover or coil spring.
CAUTIONS ADAPTOR(OPTION)
You operate AT1/2 from AC line , use AC
Adaptor (DC9v) for AT1/2.
When you don’t use for a long period, remove the battery to prevent
current leakage and leaking out of sticky substance.
If battery voltage drops, effect becomes inferior or no sound is
produced. To prevent that, replace the battery a little earlier.
Be sure to keep the battery snapped by connector into the housing,
when using AC adaptor, too.
* Even if AC Adaptor cord comes out during performance, operation
immediately changes to battery, causing no
trouble in continued performance.Power is switched on while a plug
is put into input jack. When you do not use, keep the plug off the
jack.
