Frequently Asked Questions
How do I power the unit if my battery is low?
Use an AC Adaptor (BOSS PSA-Series) connected to the AC Adaptor Jack.
Can I use this pedal with other effects units?
Yes, you can connect Output A or B to another effects unit for outputting a tempo or a mono signal.
What happens if I use the GUITAR IN jack as a power switch?
If running on battery, plugging or unplugging a cable from the GUITAR IN/BASS IN jacks will turn the power to the unit off.
How does Stereo output differ from Mono output when using GATE/PAN mode?
In mono, it applies a slicer effect; in stereo, you get a flanging effect panned three-dimensionally across the sound field.
