The Great Direct Box Comparison with Audio Samples - inSync | Sweetwater I found this fascinating and this is well-timed because I was looking at maybe getting another general purpose DI. I currently have a Pro D2 that I picked up for keyboards a long time ago. Here are my observations: P w/ flats makes everything sound the same. Really, I can barely tell any of these tracks apart soloed, never mind in a mix. No wonder engineers love this setup. The Pro DI sounds great for bass. I almost always found myself enjoying it over the JDI. It suits my taste for bass tone. The JDI has more accuracy and definition, sure, and it's actually very audibly different, but I like how the Pro DI tracks sit in the mix, as in the Pro DI has a nice sweetness that really works for bass. On a general note, there were many cases where cheap DIs sound rather nice, and some cases where an expensive DI doesn't necessarily sound better than the cheap one. So much for this notion of passive DI for active bass and active DI for passive bass. Maybe that's true for stage where there are long cable runs and you don't always get to check your levels, or maybe that was true in the old days, but for modern day recording, I think we can throw that out the window. There were many cases where I preferred a passive DI for passive bass, or active DI for active bass. I couldn't hear a lack of definition in the passive DI for passive bass, and I couldn't hear a lack of headroom for the active DI for active bass, either. In fact, the JDI sounded more detailed than a lot of active DIs. If that's your only DI, you don't need another one just to record with, just for the sake of having an active DI. It'll definitely work just fine. We obsess over recording chain, but did any of these tracks actually sound bad to anyone? Not to me. It's clear that the most important thing is what goes into the recording chain. You need a good instrument with good pickups and a good player, and you need a good take. The quality of DI is not as important as that. Even the Behringers do not embarrass. Would love to have seen the J48 and Countryman included. I feel like that's the most common question: JDI, J48, or Type 85? On a personal note, I am GASing even harder for RNDI after hearing all these tracks. Maybe it's confirmation bias because I want one, but it sounds very detailed and would work nicely into my workflow because it's clearly a different flavor than the Pro DI, which sounds quite nice and fat. Also, as much as I personally thought that the Pro DI was making better bass tracks, I felt like the JDI sounded noticeably more detailed and would therefore be better as your only DI if you needed to record other instruments, too. Would love to hear this repeated on a guitar, and there, I have a feeling that the JDI would slay the Pro DI. And if you wanted a track you could re-amp, the JDI sounds more like it would stay together better because it bakes less of its own flavor into the tone. But it's telling that even if I get a more accurate sounding DI, that I feel like I might break out the Pro DI pretty often for bass. Probably not for me because I naturally have a very bassy tone (light touch, flatwounds, 5-string) and I often end up trying to EQ out the fatness, but I often record a player who just naturally has a much thinner tone, even through the same basses with flatwounds, and I end up using shelf EQ and things like that. The Pro DI would probably work very nicely for that kind of player.
