selected in step 3 is erased.
The bypass setting of the effect and the POWER LEVEL setting
are not saved with the program.
If, while creating a sound in the preset programs mode or the
user program mode, you switch to another program or to manual
mode or turn off the amp before saving the sound that you are
creating, the changes that you made will be lost.

Restoring the factory settings

Here's how to restore all settings of the VT20X/VT40X to their factory-set

as all settings, such as custom amp settings stored from the Editor/
Librarian software, will be reset to the factory defaults.
1. Turn off the power.
2. While holding down the CH1 and CH4 buttons, turn on the amp. After
the BANK and channel buttons blink, release the pressed buttons.

Tip
button.
3. Hold down the BANK button for at least 2 seconds (until the button
changes from blinking to lit).
