Tuning the Guitar (Bypass/Tuner)
The ME-20 features a built-in chromatic auto-tuner that allows you to tune your guitar easily without changing any of your connections. Additionally, in Tuner mode, the sound output is the same as the input sound, with no effects applied (bypass). You can use the expression pedal to turn down the volume, making it unnecessary for you to turn down your amps volume each time you tune.
Press the Number 1 and 2 pedals simultaneously to switch to Tuner mode. The tuner appears in the display, and any deviation from the pitch is indicated by the Tuning guide.

fig.7seg-tuner1.eps

Tuning guide
If necessary, you can change the reference pitch. Press [ ] [ ] and the current reference pitch is indicated in the display for a brief length of time. By continuing with this operation, you can change the reference pitch, in one Hertz units, to any value from 435 Hz to 445 Hz. The setting is saved automatically, so there is no need to make this setting each time you tune. * The reference pitch was set to 440 Hz (Display: 40) when the unit was shipped from the factory.

Display Pitch (Hz) 35-45 435-445
Play a single note on the string to be tuned; play the string open. The name of the note closest to the pitch of the string played appears in the display. * Use your hand or other means to mute the other strings. You may be unable to tune the string accurately if other strings are vibrating during tuning.

Tune each string more accurately until both of the tuning guides are lit. * The larger the difference between the pitch of the string youre playing and the correct pitch for the note shown in the display, the faster the tuning guide flashes. As you get closer to the correct pitch, the pace of the tuning guides flashing slows down.

Too high

Too low
6. Repeat Steps 35 to tune the other strings. * If you are tuning a guitar that has a vibrato arm, tuning one string may cause other strings to drift.In this case, you should first tune the strings approximately so that the correct note name is displayed, and then re-tune each string.
One useful technique that makes tuning less confusing is to start slightly under the target pitch and then tune upwards little by little until the string is in tune. 7. Press the Number 1 and 2 pedals simultaneously to return to the previous mode. You can also return to the previous mode by pressing [EDIT/EXIT]. 15

This effect creates a wah effect using the pedal controller. Stepping down on the pedal creates a brighter sound, while releasing the pedal produces a muffled sound. When the wah effect is on, the pedal functions as a wah pedal. When WAH is on: Functions as a wah pedal. When WAH is off: Functions as a volume pedal.

NS (Noise Suppressor)

This effect suppresses noise and hum from the pickups.

THRESHOLD

This adjusts the effect in response to the level of noise. Increase the value when there is a considerable amount of noise. Decrease the value when there isnt that much noise. A value of 0 switches off the noise suppressor. * Setting the value higher than necessary may result in no output of sounds when the guitar volume is low. * Adjust this value until the decay of the guitar sound is as natural as possible.

MASTER LEVEL

This adjusts the level of the output from the ME-20. * Raising the MASTER LEVEL knob too much may result in sound distortion. * When the effects are all off, input and output are at the same levels as when the MASTER LEVEL knob is at the center position. * The setting of the MASTER LEVEL knob is stored in memory for each patch (p. 23). 21

Troubleshooting
bt Appears in the Display
Batteries are run down. Replace with new batteries (p. 11). Is the volume turned down? Check the volume levels on any connected amp or mixer. Check LEVEL and other volume parameters to make sure no volume setting is too low. Could the level have been lowered with the expression pedal? When the pedal is set to function as a volume pedal, sounds are not output when the toe of the expression pedal is in the raised position. Is the ME-20 in Tuner mode? In Tuner mode, the bypassed sound is output, and the expression pedal functions as a volume pedal. In this case, sounds are not output when the toe of the pedal is in the raised position. Could you be using a cable with an embedded resistor to connect a CD or MP3 player to the AUX IN jack? Use of a cable that contains a resistor may make sound from connected devices inaudible.

Power does not turn on

Is the correct AC adaptor (PSA series; sold separately) properly connected? Check once more to confirm the adaptor is connected (p. 12). Never use any AC adaptor other than the adaptor specified. Has the battery run down? Replace with new batteries (p. 11). * The batteries included with the ME-20 are intended only for confirming that the unit is functional. * This unit consumes a large amount of current, so the use of an AC adaptor is recommended. If using batteries, use alkaline-type batteries. * To reduce battery consumption, be sure to disconnect the plug connected to the INPUT jack whenever the unit is not in use. Is the plug properly connected to the INPUT jack? Check the connection once again (p. 12). * The power will not turn on without a plug connected to the INPUT jack.
Patches Cannot Be Switched
Is the ME-20 in Memory mode? In Memory mode, the display indicates the bank, the pedal indicators show the current patch, and the effect-select indicators light. Conditions other than these mean the ME-20 is in another mode, so patches cannot be changed. First switch the ME-20 to Memory mode, then continue (p. 23).

No Sound/Volume is Low

Are the other devices properly connected? Check the connection once again (p. 12). Can you hear sound through the headphones when headphones are connected? If you can hear sound, there may be a short in the cable used to connect the amp or other device, or a mistake in an external devices settings. Check the connecting cables and external devices once more. Could the MASTER LEVEL knob be turned down? Use the MASTER LEVEL knob to raise the output volume. Could the levels for OD/DS or EQ be too low? Use the parameter knobs to raise the levels.
