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 amp’s volume each time you tune.
1. 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.

2. 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.
3. 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.
