dbx DI4 Active 4-Channel Direct Box with Line Mixer - Professional Audio Interface for Live Performances, Studio Recording & Podcasting

I'm using this passive DI for a reamp loop. DAW goes out via reamp box, through a pedal chain, through the DI back in. The impedance matching works well, keeps the noise low. There's a single attenuator for both channels, but since my last pedal is stereo, the channel pair is reasonably balanced. If you're running two different signals then it may pose an issue. Similarly there's a single ground lift button for both channels, and that is great to have if you've got power loop issues.It's a good size considering what it does, does not require power, seems to be built well, and I anticipate it'll last a long time in a studio setting, but is ready for gigging too.
