A Simple and Effective A/B Selector in the BOSS Spirit
The Boss AB-2 is an essential tool for anyone looking to simplify their setup without adding unnecessary complexity. True to the brand's DNA, it goes straight to the point: reliable, immediate switching designed for the stage. Its "plug and play" concept makes it a practical solution to save time between two instruments, two amps, or two routings, while maintaining a classic pedal ergonomics.
Who Is the Boss AB-2 For, and In What Contexts Should It Be Used?
The AB-2 is aimed equally at guitarists and bassists who need fast and clean switching: changing guitars between songs, alternating between a clean amp and a distorted amp, switching from one effect to another, or routing the signal to a tuner without breaking the flow of the set. In the studio, it helps to compare two chains (or two amps) instantly; live, it becomes a small pedalboard "hub," easy to operate and easy to read thanks to its LED indicators.
Switching, Indicators, and Connectivity: The Essentials, Well Thought Out
The Boss AB-2 operates as a pedal A/B selector with indicators to visualize the active channel: A (red) and B (yellow). Its strength lies in its routing versatility: thanks to reversible operation, you can use it interchangeably to select inputs (for example, two guitars to one amp) or outputs (for example, one guitar to two amps or two effects paths). The 6.35mm Jack connectivity allows immediate integration into the pedalboard, with clear and quick wiring setup.
Sound
The Boss AB-2 is not designed to color the sound: it is a "utility" pedal made to route your signal, not to transform it. Its value lies in the feel of use and reliability: fast switching, clear selection between A and B, and immediate visual feedback. In a playing context, this translates into a smoother workflow: fewer manipulations, cleaner changes between instruments or amps, and a more professional setup both on stage and in rehearsal.

After several weeks of use, positive results. Does his job very well. Two negative points:
There is no possibility of an external power supply and to change the battery it is necessary to use a screwdriver.Automatically translated

It works great. Quiet and no signal loss. Alone, the power supply is not up to “9Vdc” standards: mass isolation is mandatory!”

Effective, without altering the sound.
