Independent shopping perspective
The Korena take
An active ABY switcher for running one guitar into two amps — pick A, B, or both — at about 3.6 by 3.8 inches on the board.
Strong match
Who this is for
- Running a clean amp and a dirty amp from one guitar
- Switching between two rigs mid-set without unplugging
- Stacking both amps together for a bigger rhythm sound
Consider the trade-offs
When to look elsewhere
- Single-amp players who only need a tuner and drives
- Anyone needing to switch between two guitars into one amp
- Crowded pedalboards with no room for another 3.6-inch box
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
ABY switching
Three states: amp A alone, amp B alone, or both at once. The both-amps mode is where two-rig setups get their size.
Detail 03
3.62 x 3.78 inches
Roughly a standard pedal footprint but wider than a compact drive, so budget a full slot on the board.
Detail 04
1.23 pounds
Heavy for its size, which is typical of switchers with transformers inside. It stays put on a board.
Final check
Know before you order
- 01You need a second amp and a second speaker cable run before this does anything
- 02Two amps on separate outlets can hum; expect to sort out grounding
- 03An active box needs power — confirm your board supply has a free slot
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I run both amps at the same time?
Yes. That is the point of the Y position. You can run amp A, amp B, or both together, switched by foot.
02Why active instead of a cheap passive splitter?
Splitting a guitar signal two ways halves what each amp sees and loads the pickup. An active circuit drives both amps at full level over long cables.
03Will it fix hum between my two amps?
Two amps on different circuits commonly hum from a ground loop. Address it with the switcher's grounding options and by powering both amps from the same outlet.
04Does it work for keyboards or bass?
Yes. Anything with an instrument-level output that you want to send to two amplifiers works the same way.
