Incredible

By Kevin Glenn

from Palatine, IL

Comments about Radial Engineering JDI MK3 Passive Direct Box:

This green DI box is just awesome. I am using it to send the sound my of Spector Euro 5 LX bass to the sound guy at shows. The sound is dead on: my bass sounds like my bass through the PA system - nothing added and nothing subtracted from my original tone. The unit is tough steel and will survive ANY kind of punishment. The parts are of the highest quality. Don't settle for a cheap DI box, buy this one.

Very Clear Sound thru PA

By Rickie

from Virginia

Comments about Radial Engineering JDI MK3 Passive Direct Box:

The Radial JDI gives me tremendous clarity with my acoustic guitar. The difference between a DI and the Radial JDI is so obvious to your ears. (OK, the price difference is so obvious to your wallet). Anyways, if you have a decent guitar and you want it to come out of the PA with no loss in sound quality then you have to go with this. You can really hear the difference.

Radial JDI Direct Box

By Dr. Carl A. Pecoraro

from Egg Harbor Township, NJ

Comments about Radial Engineering JDI MK3 Passive Direct Box:

If you can afford it, buy it. Particularly suited to pre-amplified musical instruments, but also suprisingly adept at passive instruments. Plugging in my Gretsch 6120 or Hagstrom Viking with passive pickups from the JDI directly into my sound system does not yield the sterile bland sound that might be expected without a guitar preamplifier. In fact, when using the through input out of this box to a guitar amplifier for stage and main volume, and blending this sound with the output from the main sound system gives a very pleasing full bodied sound. It always pays to buy the best.

Radial JDI top notch

By John Nyerges

from Rochester NY

Comments about Radial Engineering JDI MK3 Passive Direct Box:

We compared this DI to others in a studio setting mostly with electric bass and found that this blew all the others away. The bass frequencies came through more focused, in phase, quiet and full. Just beautiful, built like a tank. Don't waste your money on a cheap DI. I own one. I bought several of the active and passive versions for our studio.

Comments about Radial Engineering JDI MK3 Passive Direct Box:

I first purchased a J48 Active Direct Box to use with my two basses with active equalizers. I was so happy with the J48, I purchased a JDI to use with my two passive basses. Wow! Nothing negative about this unit and everything positive. The sound out of the PA is exactly the same as what came out of the amp. You can pay less for a lot less. Or, pay a little more and get the best.

Comments about Radial Engineering JDI MK3 Passive Direct Box:

Used this to tame my EMG X-Series pickups with a 24-volt mod. It allows the full headroom of the pickups into my interface with utter clarity. In a word, perfection. I love how rugged and well built this is, and I plan on keeping it forever.

Comments about Radial Engineering JDI MK3 Passive Direct Box:

After hooking a keyboard into the main house system I noticed it sounded harsh, like something stayed maxed out in the signal line somewhere. I changed the DI to one of these units and the better quality Jensen transformer really makes a difference. Very pricy, hence only 4 stars. But if sound clarity and tone are essential in performances then it's well worth the price for high output instruments/signals.
