Frequently asked questions

What are the two input systems on the CUBE-40?

The CUBE-40 has two input systems: Overdrive and Normal. Connect to the Overdrive jack to obtain distortion sound, and use the Normal jack when you do not hope to distort the sound or when using a big output guitar.

How do I connect an external speaker?

You can connect an external speaker system with 8 ohms or over to the External Speaker Jack. This allows sound to be produced through the combined speaker, which is effective when sound spread is required.

What should I do if the pilot lamp lights but no sound is produced?

If the pilot lamp lights but no sound is produced, the volume is likely set to minimum. You should turn the volume knob to a proper level.
