The Vintage ABY Line Guitar Effect Pedal LEF-330 is a comprehensive channel switch pedal designed for versatile signal routing. It allows you to switch one signal to two different outputs, making it ideal for use with amplifiers, speakers (using speaker cables), and pedalboards. The mode-choosing switch enables A and B channels to transfer either separately or simultaneously, supporting signal paths from A/B to Y or from Y to A/B. True bypass ensures a transparent tone, and the LED indicator shows the working state. This pedal can operate without a power supply (though the LED will not light up). Made of solid zinc alloy, it is durable and sturdy. Its mini size saves space on your pedalboard.
