## Customer Reviews

### ⭐⭐⭐⭐⭐ Got ground buzz?
*by B***N on May 12, 2024*

After buying a power conditioning strip, trying to plug everything into one ground, unplugging different things in my room to see what might be causing the buzz, these little boxes have improved my amp buzzing situation more than anything else. I am running two fender blues deluxe reissues and then also an acoustic A40 amp and i was getting terrible ground loop through my instrument cables. I bought three of these and ran my instrument cables out of my looper with these closer to the looper than the amp with excellent results. Now they are part of my pedalboard. The passive technology uses a transformer to cut out the ground connections through the instrument cables while allowing the tube amps to be safely grounded to the AC power. It took awhile for me to figure this all out so i thought maybe i could save some musicians the trouble. These work well and they are not that expensive.

### ⭐⭐⭐⭐⭐ Really good at a great price point.
*by B***R on May 18, 2022*

I got this to help with ground loop noise from my amp's DI connection to my DAW. It works really well, it's compact enough to put in a gig bag and it's budget friendly.

### ⭐⭐⭐⭐⭐ True isolation
*by G***N on May 14, 2022*

Using it between the mixer output and the computer audio input for live streaming at our church. Completely eliminated all hum, static and crackling. We tried many other fixes before this and none worked. This isolation DI has solid transformers for isolation between the primary and secondary windings without altering the audio quality. A quality product. Does what it's supposed to perfectly. Love it.
