Rowin LEF-330 ABY Switcher Pedal

The Rowin LEF-330 is a compact ABY line selector built for guitarists who need to route one instrument signal to two amplifiers or combine two sources into a single output. Its passive design operates without external power for the audio path, while a DC 9 V supply only illuminates the status LEDs. The pedal suits players seeking a space-saving routing solution on a crowded board.

Full Metal Mini Chassis and 1/4" Jacks

A zinc-alloy enclosure measuring 12 cm in its boxed dimensions protects the internal PCB and withstands stage handling. Three 1/4" mono jacks labelled A, B and Y provide straightforward connectivity for instruments, amplifiers or pedal chains. The footswitch toggles between A and B outputs, while a separate sliding switch selects combined A+B operation that cannot be triggered by foot.

Check Power Needs and Switching Method Before Buying

Verify that your power supply delivers DC 9 V with a negative-centre plug if you want the LED indicators to function, though the audio signal passes without it. Confirm that your intended use matches the footswitch behaviour: it only selects A or B, so combining both signals requires bending down to move the slide switch. Ensure 1/4" mono cables suit your amp and pedalboard connections.

  • Switch between two amps with a single pedal
  • Combine both amp signals using the slide switch

  • Rugged zinc-alloy case withstands stage use

Questions about this item

How does the 1/4" mono jack interface handle signal routing between A, B and Y channels?

The pedal routes one input to two outputs or combines two inputs to one output using the sliding switch; the footswitch toggles between A and B only, while A+B mode requires the slide switch.

What are the physical dimensions and jack layout for pedalboard mounting?

The mini enclosure measures 12 cm with box and has three 1/4" mono jacks labelled A, B and Y on the top face for instrument or amp cables.

How is the unit powered and what is the correct polarity for the DC jack?

It accepts a standard 9 V DC supply with negative centre pin; the pedal also works passively without power, but the LEDs will remain off.
