My Buying Guides on Boss Line Selector Ls-2 All Possibilities

When I first started looking into the Boss Line Selector LS-2, I wanted to understand all the possibilities it offers and how it could fit into my rig. After spending some time with it, here’s what I’ve learned, which might help you make an informed decision.

Understanding What the Boss LS-2 Is

The LS-2 is essentially a line selector and mixer pedal that lets you route your signal in multiple ways. For me, it’s been a game-changer because it allows switching between different signal chains or combining them without unplugging cables. If you have multiple guitars, amps, or effects loops, this pedal helps keep everything organized and accessible.

Types of Switching Modes

One of the biggest reasons I chose the LS-2 is because of its three switching modes:

  • A <-> B Mode: Switch between two separate inputs or outputs. Perfect when I want to toggle between two guitars or amps.
  • A + B Mix Mode: Mix two input signals and send them to one output. I use this when blending two different effect chains for unique tones.
  • A/B + B Mix Mode: Offers even more flexibility by allowing me to switch between A, B, or a mix of both. This versatility was a huge selling point for me.

Input and Output Options

The LS-2 has two inputs and two outputs, plus a dedicated send/return loop. This setup means I can:

  • Route signals to different amps or pedals.
  • Use effects loops on one or both signal paths.
  • Seamlessly switch or mix signals without signal loss.

This flexibility was crucial for my live setup where quick changes are needed.

Build Quality and Design

Boss pedals are known for their rugged build, and the LS-2 is no exception. It’s compact, sturdy, and roadworthy. The simple footswitch and LED indicators make it easy to use on stage or in the studio, which I appreciate since I don’t want to fiddle with complicated controls during a performance.

Power Requirements

I power my LS-2 with a standard 9V adapter, which is convenient since it matches most of my other pedals. It also accepts a 9V battery, though I prefer using an adapter for longer sessions.

Compatibility and Integration

The LS-2 works well with both analog and digital pedals. Since it’s a buffer and line selector, it doesn’t color the tone, which is important to me. Whether you’re running classic fuzz boxes or modern multi-effects, it integrates smoothly.

Who Should Consider the LS-2?

I’d recommend the LS-2 if you:

  • Need to switch between multiple guitars or amps quickly.
  • Want to blend two effect chains to create unique sounds.
  • Have complex pedalboard setups requiring neat signal routing.
  • Perform live and need reliable, intuitive switching options.

Things to Keep in Mind

While the LS-2 is versatile, it’s primarily a utility pedal rather than an effect. If you’re looking for tone-shaping features, you’ll need other pedals alongside it. Also, learning how to maximize its routing capabilities might take some experimentation, but it’s worth the effort.

Final Thoughts

Buying the Boss LS-2 was one of the best decisions I made to streamline my rig and expand tonal possibilities. Its robust build, multiple routing modes, and ease of use make it a must-have for serious guitarists looking for flexible signal control. If my experience helps you get the most out of this pedal, then I’m glad to share!
