This may be the best all around DI box on the planet. It's not much more money than the industry standard Radial JDI and J48, and it blows both of them away. The reach on the low end is insane. It's like adding another octave on the bottom of a bass guitar compared to a passive DI like the JDI. Not in an inflated or bloated way, it just goes a lot deeper. It keeps the speed and clarity on the top end you get from an active DI like the J48, but without being harsh. It's has that warm, smooth transformer sound you get from a good passive DI but with the high end fidelity and punch you get from an active DI. It really is the best of both worlds.I typically use them for bass DI live, but they also excel at synths and keyboards. I've yet to find an application that they don't better my JDIs and J48s. My only problem is that I need more of them.Build quality is very good. Mine get used in a live environment almost every day and are no worse for wear. These things are tanks.
