I've had my RNDI (Active Transformer Interface) for a few years "and Love it" I use it for my Acoustic Guitars and Bass. The tone is clear and full, giving a beautiful balance. The device is also Silent with no ground floor noise, very nice Direct Interface.

Thanks to the professionals at Sweetwater, amazing input and help, always there get what I need!

I didn't think a DI box would really create such an improvement in my tone, I've had a couple other ones and really high class inputs on my interface. To be honest I bought with the intent of just finding out of it really matches up to the reviews. With its extended range it really does deliver on tone for both guitar and bass (especially bass). I will admit the differences are subtle but they make a big difference in the context of a mix. Being an active box with a sort of hybrid operation it doesn't choke out but rather saturates rather nicely and allows my plugins to drive nicely. It does isolate interference but if you have noise on the HiZ side you'll still have noise on the HiZ side obviously. It works great for my American Pro Telecaster with humbuckers and my Charvel PJ whether I'm going in active, passive and has the headroom to take a boost/overdrive with great clarity. If you're on the fence check it out because it made me a believer. I might one day grab a REDDI or a Broughton P15 for the flavor but this is a great DI for the money compared with others in class/price range.

This is a very true DI. True to the exact signal you send to it. I don't know a lot about the details of the circuit inside the RNDI but I do know they make their own proprietary transformer as well as class A discrete FET amplification electronics.

The low end was extremely tight and well defined, but clear.

I think clear is an adjective that is synonymous with this DI. It is very pristine and doesn't make your tone pretty or add any flavor - but for me, that is the point. This is probably the opposite of a fancy tube DI, which applies lots of tube coloration and saturation, such as the Noble or REDDI - I think those are meant to accomplish a totally different end.

I've had this for a few years. It's solid, I use it for bass DI and guitar amp modeling. It's pretty amazing.

This is great because it has a transformer. If you want something that gets a little transient smoothness this could be fun to work with. I use this in many different ways. I love the speaker option, I use it record after my amp and before the speaker, then I use a speaker simulator give me more speaker options.

I can't find a bass that sounds bad through this DI! It's a must-have tool for any live sound or recording situation.

Josh Hacker

I've always viewed a DI Box as nothing more than an impedance-matching tool, but the moment I ran my bass though the Rupert Neve Designs RNDI, I changed my mind. This DI is more like a preamp, delivering the colorful, harmonically rich punch I look for in a rock bass tone. It sounds amazing live, but the beauty of the RNDI really comes though when I track original music in my studio. It's like my bass comes in EQ'd and compressed to perfection, saving me a ton of mixing time.
