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.

Works great
For it being $15 or around that price I'd say it's way worth the money. I was looking and saw that a ground plug was around 60 bucks and wasn't going to buy that right away and saw this and bought it instead. It's pretty easy to use especially with the diagram on it. I wasn't sure if it was going to play through the amp or not but it does and I haven't tested it on a saw yet so I can't say anything about that. For the ideas it wants talked about. Doesn't need a battery, the quality is good.

Works awesome. Exceeds price point
Using for at home rehearsal space. V Drum left out to the DI into mixing board. Awesome!!! I’m gonna buy a second and third for keyboards and bass

Works well
Seems like a product well built and built to last. Very sturdy, passive, selectable attenuation + ground float. Alas for my intended purpose , split box between Amp and ps5 rocksmith, signal attenuation is way too high, either you get good signal to ps5 or the amp,not both. And of course choice is clear,it's gotta be ps5 else rocksmith doesn't detect what you play. Signal to Amp (or actually signal processor before) is so low that guitar effects don't work. Don't get me wrong, this isn't fault of this box, just the setup. Of course I could have a signal booster before, but it defeats the purpose, I'll look for active DI box instead - in hope getting less attenuation. If input signal is from e-piano,DAW what ever I'm sure this is perfect for the job.

Fantastic DI box for stage or studio
Fantastic Little DI box for the price. It does the job and does it reliably. As it is passive, it won't boost a low signal, but for electric guitars and active acoustic guitars, this thing is a wonderful addition to the gig bag. The price is set so you can buy 2-3 of these for the price of a stronger brand name. In the end they do the same thing and the quality of this is comparable. If you need signal boost, go with an active DI, but otherwise, the Pyle Pro DI is a bargain for musicians on a budget needing reliable gear.

This thing works great. Had a ground loop from somewhere in my studio that I could not figure out for the life of me but since I started using this...no hiss, no hum...perfectly quiet recordings. Thanks Pyle!

Good!
Works as it should! Great for the price nice to have on you just in case of emergencies. Straight from a pedal board to the board. Happy with purchase, and would purchase again.

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.
