Well constructed and works well
Very well made with attenuation transformer and clear functional diagram on the case, seems to work well though I have not tested it extensively yet.

Excelente opción y un excelente precio
La diferencia es de noche a día. Yo la utilizo para conectar mis guitarras y bajos a mi interface de audio (scarlet) y el resultado es muy bueno, corta todo ese ruido que había antes y obtienes una señal limpia. La caja en sí está muy bien construida, se siente de buenos materiales. La verdad es la mejor opción por el precio, no duden en comprarla.

Great box for a great price!
Great direct box for the best price I've seen. Works well... the sound guy at church said it not only gave a stronger signal than my setup had been providing, but it also fixed an annoying hum that he couldn't isolate before (using the church's direct boxes). The only recommendation: with the ground lift button (it's a button, not a switch), maybe either add the word "lift" or switch your on/off indications. Since it's a lift, technically (as printed in the instructions), when it's engaged ("On"), the GROUND is disengaged or off (lifted). Right now, when you look at it, it reads that the GROUND is ON or OFF. For those who work with tech all the time, they probably understand the difference, but others might not. Regardless, once you figure out the right position, it works great.
