On the advice of experienced studio musicians, I bought a DI box for recording guitar and bass. (Not this one). I was tired of overplaying and still getting anemic, lifeless guitar sounds on playback. My first DI box alleviated the problem but I still couldn't get the full-blooded sound of a well amped guitar. My guitar sounds still lacked the midrange definition I was looking for, so it was back to the marketplace. All the reviews mentioned the Radial DI so I tried it. I don't know how one transformer can be so different from another (a DI box is basically a transformer) but it is! Now I can just play without having to think about compensating for signal loss. Works well for bass, too. Much more body and less string slap. It's expensive for what it is but it works.

1) Ya lo tengo probado por aproximadamente unos 4 meses y el artículo es muy bueno.2) Su función PAD funciona correctamente3) El material de fabricación es muy resistente4) El precio podría ser algo caro, pero la verdad es que vale mucho la pena por la calidad de audio que se mantiene, los materiales de fabricación, la función PAD y diseño.

There's a noticeable difference in the clarity of my tone when I use this. Even if im not recording, Ill run it with my headphone amp in the thru jack, and the tone just sounds much less harsh. I'll often run a zoom recorder through the XLR jack while I'm doing this so I can record a good DI if the need arises.Also, as someone with a guitar that runs a little spicy, that PAD is a great thing to have. I use it with my practice amp just for that reason.

Sturdy, works great. Owned one of these previously and line-lift button finally would not work, BUT, I got 10+ years out of it.

I use it with my Classicals, Steel Strings acoustics, my Hollowbody Ibanez and Fender Stratocaster guitars and it improved their sound. A metal enclosure will provide resistance to the abuse and sometime neglect that it endures when on the road. I love it and highly recommend it.

Conosco la qualità Radial perché ho altri loro prodotti ma fino a poco tempo fa non avevo bisogno di una DI e soprattutto con 2 output. Ne ho provata una di altra marca, economica, ma l'ho dovuta restituire subito.. con questa PRO DI ho risolto il problema! Qualità del suono restituito eccezionale, lo valorizza senza colorarlo. Robustezza di un carrarmato. La qualità si paga e con i prodotti Radial Engineering si va a colpo sicuro ad occhi chiusi. Venditore eccezionale: il tutto è arrivato con 1 giorno di anticipo e impacchettato con cura e protezione più che adeguata.

Ne fonctionne pas avec une basse Fender précision, que ce soit en position active ou passive.Je ne reçois que des parasites et un son très très lointain en sortie XLR, même après plusieurs essai, raccordements, etc...Tout fonctionne bien avec mon compresseur qui a aussi une sortie XLR, donc ce n'est pas un problème de cordon, ni de raccordement.

As the leader of the sound team in my congregation, I found myself regularly fetching replacement direct boxes for the Berhringer and other brand boxes on stage, due to noise or him, insufficient gain or just a dead box. What I noticed over time is that I never had to replace any of the Radial boxes, and in fact the musicians would sometimes ask me specifically for one. So I started stocking up on them and eventually replaced all of the other boxes with Radials. Now I simply don't worry about the boxes at all--they just work and they work well.These boxes are compact and simple, they sound great with no audible noise, and they're solid as a rock. The Pro D2 stereo boxes are just as reliable, and I've purchased a few of those to cover our keyboardists and drum sets with success.We have a couple powered Pro48 boxes that work well, but at some point I hope to have passive direct boxes exclusively, and leave the phantom power for our condenser microphones. These passive boxes are perhaps the most reliable component in all our sound equipment and I highly recommend to all musicians and venues, big or small.

These units have great sound and functionality, and are incredibly durable. My only complaint is that the foam rubber pad glued to the bottom will eventually peel off or fall apart. For my use, a smooth metal surface on the bottom is just fine, but for others who need the pad to keep the unit from slipping, be aware that you may have to reaffix some foam rubber after a year or two of use.
