Troubleshooting

The power won’t come on /

the CHECK indicator doesn’t light

●

Is the specified adaptor (PSA-series, sold

separately) properly connected?

Check the AC adaptor connection (p. 7, 8).

* Never use any AC adapter other than one

specified for use with the ML-2.

●

Is the battery low or dead?

Replace it with a new battery (p. 11).

* The battery that is supplied with the unit is for

temporary use, intended primarily for testing

the pedal’s operation.

* The use of an AC adaptor is recommended as the

unit’s power consumption is relatively high.

Should you prefer to use a battery, please use the

alkaline type.

* To prevent unnecessary battery consumption, be

sure to disconnect the plug from the INPUT jack

when not using the effects unit (p. 5).

●

Is your guitar properly connected to the IN-

PUT jack?

Check the connection once more (p. 7, 8).

* A cable must be connected to the INPUT jack to

allow the effect to be turned on.

* If a cable is connected but no power is supplied

to the unit (either from a battery or an AC

adaptor), the CHECK indicator will not light

when you try to turn the effect on.

No sound / low volume

●

Is your instrument properly connected to

the ML-2?

Check the connection once more (p. 7, 8).

●

Is the LEVEL knob set too low?

The further counterclockwise you turn the

LEVEL knob, the more the volume is re-

duced when the effect is on. Turn the LEVEL

knob clockwise to increase the volume.

●

Is the volume turned down on any guitar

amp or effects device you have connected?

Check the settings of the connected device.

●

Is the battery low or dead?

Replace it with a new battery (p. 11).
