The Rowin ABY Line, listed as the LEF-330, is a utility pedal from Rowin that handles A/B/Y routing for a guitar signal1. It is a switcher rather than an effect: it passes your sound through unchanged and simply decides where it goes.
What it does
An ABY switcher gives you three routing choices from one input:
- A: send the signal to output A only, such as one amp1
- B: send it to output B only, such as a second amp1
- Y: send it to both at the same time1
For a player, that covers the common switching jobs: moving between two amplifiers without unplugging, running two pedal chains, or splitting one guitar across two amps for a layered sound. The ABY Line is classed as a utility pedal, an ABY switcher and signal router, so it adds no gain, filtering or processing of its own1. It belongs to the wider family of switching pedals, alongside loop switchers and channel selectors.
