Boss LS-2 Line Selector — Routing Center for Complex Pedalboards

The Boss LS-2 Line Selector pedal is the easy way to switch settings among several effects devices or amplifiers, or route input and output signals. Two line loops and six looping modes cover applications from simple A/B switching to parallel blending and amp selection. The LS-2 is the right choice for guitarists and bassists running multi-amp rigs who need single-stomp access to different signal paths.

Six Modes, Two Loops, One Stomp

What sets this model apart from a basic A/B box is its six looping modes, accessed through a single Mode knob. Players can alternate Loop A and Loop B, blend A and B for parallel effects, or use the pedal as an output selector between two amplifiers. Each loop has its own Level control running from minus infinity to plus 20 dB, so the LS-2 doubles as a clean boost or volume cut when one loop is left empty.

Switching Architecture — Routing Logic

A single stomp cycles through the programmed mode, while two LEDs indicate which loop is active. Buffered bypass keeps the signal intact when both loops are disengaged, avoiding the high-frequency loss that plagues long chains of true-bypass pedals.

• Type: Switcher — a routing pedal, not an effects generator
• Bypass: Buffered bypass — preserves tone across long cable runs
• Controls include Level A, Level B, and Mode knobs — three top-panel controls cover all routing decisions

Inputs and Outputs — Loop Connectivity

The unit exposes two complete effects loops, each with its own Send and Return jack, plus a main Input and Output. This makes it equally useful for inserting rack effects into a pedalboard, splitting a guitar into two amps, or running parallel effect chains.

• Inputs: Mono Input, Send A, Send B — three 1/4-inch jacks feed the loops
• Outputs: Mono Output, Return A, Return B — three 1/4-inch jacks return processed signals
• Nominal I/O Level sits at -20 dBu — line-level friendly for rack integration

Power and Build — Stage-Ready Hardware

Beyond routing, the LS-2 acts as a miniature power hub for a BOSS pedalboard. With a PSA-series adaptor connected, the DC OUT jack can daisy-chain power to several other BOSS compact pedals using the optional PCS-20A cable.

• Power Supply: 9V battery or PSA-series AC adaptor — with DC OUT for daisy-chaining
• Current Draw: 30 mA — efficient enough for long gigs
• Dimensions: 73 × 129 × 59 mm, 430 g — fits any standard pedalboard slot
