Before leaving Fair Deal Music, this used pedal will be checked to make sure it is ready for its next owner. Our assessment includes:
This Boss AB-2 has been tested as part of our used pedal inspection process. The switching operation, jack sockets, indicator lights and battery operation are checked so it can be used with confidence in a pedalboard, practice setup, studio rig or live environment.
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.
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.
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.
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.
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.
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.
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.
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.
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.
A useful pedal for beginners who are starting to build a more practical setup, especially if they use more than one guitar or want an easy way to route to a tuner or second amp.
Ideal for players who rehearse, record or gig and need simple signal routing without buying a larger line selector.
A practical utility pedal for working musicians who need fast guitar changes, backup instrument routing or simple amp selection in a compact format.
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.

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.
