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

When I first started exploring the Boss Line Selector LS-2, I quickly realized how versatile this little box is. Whether you’re a guitarist, bassist, or even a sound engineer, understanding all its possibilities can really elevate your rig. Here’s my detailed guide based on my own experience with the LS-2 and the different ways you can use it.

Understanding What the Boss LS-2 Line Selector Is

The LS-2 is essentially an A/B/Y switcher and mixer combined into one compact pedal. It allows you to switch between two different signal paths or combine them. I found it especially helpful for managing multiple effects chains or routing signals to different amps without unplugging cables constantly.

Key Features I Looked For

  • Multiple Modes: The LS-2 offers A/B switch, A/B blend, and mixer modes. Each mode serves a different purpose depending on your setup.
  • True Bypass Switching: This ensures your tone remains pure when the pedal is off.
  • Compact Size: I appreciate how it fits easily on my pedalboard without taking up too much space.
  • Durability: Boss pedals are known for their rugged build, and the LS-2 is no exception. It can handle heavy gigging.

All the Routing Possibilities I Discovered

  • A/B Switch Mode: This is perfect if you want to switch between two instruments or two amps. For example, I use it to switch between my electric guitar and acoustic guitar going into one amp.
  • A/B Blend Mode: In this mode, you can blend signals from two sources. I’ve used this to mix two different effects chains together to get unique tonal combinations.
  • Mixer Mode: This mode lets you combine two inputs into one output or split one input into two outputs. It’s great when you want to send a single guitar signal to two different amplifiers simultaneously, creating a richer sound.

Why I Chose the LS-2 Over Other Line Selectors

I compared the LS-2 with other line selectors and mixer pedals on the market. What stood out to me was its ease of use combined with Boss’s reliability. The multi-mode functionality means I don’t need multiple pedals to achieve different routing options, saving money and pedalboard space.

Things to Keep in Mind Before Buying

  • Power Supply: The LS-2 runs on a 9V power supply or battery. I recommend using a dedicated power supply for uninterrupted performance.
  • Cable Management: Because you might be running multiple cables, make sure your pedalboard layout accommodates easy connections to avoid signal loss or tangling.
  • Understanding Your Signal Chain: Before buying, consider how you want to route your signals. The LS-2 is flexible, but knowing your setup will help you get the most out of it.

Final Thoughts From My Experience

The Boss Line Selector LS-2 is a versatile tool that has enhanced my live and recording setups dramatically. Whether you want to switch between guitars, blend effects loops, or run multiple amps, this pedal covers all bases.
