Schönes Teil

Nutze es um meine Stereo Effekte auf zwei Amps zu splitten und es funktioniert auch, einziger Abzug ist die fehlende Isolierung der beiden Kanäle um kein Hum zu bekommen. Ansonsten top

Gran elección

Chinarro 19.05.2026

Cumple su función de maravilla, cero ruido y cero "pops", que es lo que se puede pedir en un pedal de estas características. Lo uso para mandar la señal de la guitarra desde las dos salidas de un Boss IR200 -con lo que consigo dos líneas con distintas cabinas- hacia dos efectos estéreo, obteniendo al final dos canales estéreo para la guitarra. La única pega que le pongo y por eso le quito una estrella es que los conmutadores de fase y modo del pedal se encuentran en la parte delantera, y dependiendo de dónde lo coloques en la pedalboard lo puedes tocar sin querer con el pie, con lo que la guitarra se mutea. Pienso que los laterales sería mejor lugar para colocar los conmutadores
