Why Choose The Boss AB-2 2-Way Selector?

Simple A/B Signal Switching

The Boss AB-2 is designed for one clear job: switching between A and B signal paths. This makes it extremely useful for players who want to keep their setup practical and easy to manage.

You can use it to connect two guitars to one amplifier, one guitar to two amplifiers, or route a signal between two destinations. It is a simple solution for players who do not need the extra complexity of a larger line selector.

Useful For Guitars, Basses, Keyboards And Amps

Because the AB-2 uses standard 1/4" jack connections, it can be used with a wide range of instruments and equipment. Guitarists can use it to swap between instruments mid-set, bass players can use it for backup instrument changes, and keyboard players can use it to route signals quickly.

It is also useful for amp selection, tuner routing or simple live signal management.

Clear A/B Indicator Lights

The AB-2 includes indicator lights so you can see which route is selected at a glance. This is especially useful on dark stages, in rehearsal rooms or when switching quickly between instruments or outputs.

Compact Boss Format

The AB-2 uses a small footprint that fits easily into a pedalboard or gig bag. It is not a standard Boss compact pedal enclosure; instead, it has a low-profile selector format designed for straightforward utility use.

No Menu Diving Or Programming

There are no presets, modes or hidden settings. The AB-2 is ideal for players who want a simple switch that does its job immediately.

Comparison Against Popular Alternatives

Boss AB-2 vs Boss LS-2 Line Selector

The Boss LS-2 Line Selector is more advanced, with level controls and multiple routing modes. The Boss AB-2 is simpler and better suited to basic A/B switching.

Choose the AB-2 if you only need to switch between two inputs or outputs. Choose the LS-2 if you need blend options, level balancing or more complex routing.

Boss AB-2 vs ABY Pedals

An ABY pedal can often select A, B or both outputs together. The Boss AB-2 is a straightforward two-way selector rather than a full ABY unit.

Choose the AB-2 for simple A/B switching. Choose an ABY pedal if you need to run two amps at the same time.

Boss AB-2 vs Tuner Output On A Pedal

Some pedals include a tuner output, but that output may not offer the same manual routing flexibility. The AB-2 gives you a dedicated footswitch for selecting between paths.

Choose the AB-2 if you want a specific, physical switch for routing. Use a built-in tuner output if you only need a permanent tuner connection.

Boss AB-2 vs Basic Passive Switch Boxes

Basic passive switch boxes can be very affordable, but the AB-2 offers Boss build quality, a clear switching format and visual indicators, making it easier to use in live situations.

Why Choose An A/B Selector Pedal?

An A/B selector pedal is one of the simplest ways to make a rig more flexible. Instead of unplugging cables mid-set or reaching behind an amp, you can select between two instruments or two outputs with a footswitch.

For live players, this can make changeovers faster and cleaner. For home and studio players, it can make comparing amps, pedal chains or instruments much easier. A selector pedal does not create an effect sound like overdrive, delay or reverb, but it can make the whole setup easier to control.

Story & Context

Boss is best known for rugged, stage-friendly pedals that solve real problems for musicians. The AB-2 fits into that tradition as a practical utility pedal rather than a sound-shaping effect. It is designed for players who need dependable switching without a complicated setup.

The AB-2 remains useful because many guitar, bass and keyboard rigs still need simple routing. Whether you are switching instruments, comparing amps or simplifying a pedalboard, this is the kind of compact tool that can quickly become part of a regular setup.

Technical Specifications

Specifications are based on official Boss AB-2 product information.

Power Requirements

The Boss AB-2 is powered by 2 x AAA batteries. Boss lists the current draw as 5 mA or less.

This selector does not use a standard external pedal power input, so fresh AAA batteries are required for indicator operation.
