Detail 01
A/B switch
One input goes to output A or output B, never both. Think of it as a fork in the signal path you step on.

Independent shopping perspective
The Korena take
Footswitch that flips one line input between two destinations, or two sources into one. For performers switching signal paths hands-free.
Strong match
Who this is for
- Switching between two amps or two signal chains onstage
- Sending a feed to house or to a tuner path
- Podium and AV setups needing a foot-operated source change
Consider the trade-offs
When to look elsewhere
- Players wanting tone shaping — it changes routing, not sound
- Anyone needing to blend two sources at once
- Mic-level or speaker-level switching
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Line input selector
Built around line-level signals, so it lives after preamps and interfaces rather than between guitar and amp.
Detail 03
Footswitch operated
Both hands stay on the instrument. Changes happen at the moment you need them instead of between songs.
Detail 04
Pedal-format enclosure
Sits on a pedalboard or stage floor and takes being stepped on, unlike a rack unit you have to reach for.
Detail 05
Signal routing, no processing
Nothing is added to the signal. What comes out of A or B is what went in.
Final check
Know before you order
- 01Cables are separate — you need three for a full A/B setup
- 02Check whether your sources are line level, not instrument or speaker level
- 03Switching mid-signal can pop; mute or lower levels when changing paths
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use it to switch between two amps?
Yes, that is the core use. One input feeds either output A or output B, selected by foot, so you move a signal between two destinations live.
02Does it run both outputs at once?
No. It selects one path at a time. If you need two destinations fed simultaneously, you want a splitter instead.
03Will it color my tone?
No. It only changes where the signal goes, not what it sounds like.
04Does it need a power supply?
Check the unit before setup and plan pedalboard power accordingly, since footswitch boxes vary between passive and powered designs.
