    Comments about Radial Engineering JDV MK3 Direct Box:

    Although a bit pricey for a non-performing, retired musician,I must say I wish I would have had one of these back in the day. Very quiet, even when splitting my 3-way Bass System (which is why I bought the thing). The "Vary-Z Drag" does not seem to do anything dramatic, like I had hoped, having tested it with a hot, active Stingray and then a passive Precision Bass, I just run it at 12:00 O'Clock and both basses sound AWESOME & CLEAN! All the other bells and whistles, well, my old, blown-out ears can't discern what they are accomplising but given the quality of the unit I'm certain the ears of a professional engineer would notice. It does what I wanted it for (clean, quiet 3-way split)perfectly. So I am happy with it.

    A great DI for guitar

    Comments about Radial Engineering JDV MK3 Direct Box:

    For me, this product makes such a difference in my DI guitar signal. As I wrote above, I seem to gravitate towards NON USE of any of the additional function buttons with this unit. But I am still experimenting. Up to now, either I cannot convince myself that these additional buttons and knob improve my sound or make a significant difference.

    I use this product with both electric and acoustic electric guitars.

    Does that mean that their lesser expensive similar DI may be a better offer? I do not know, but may choose to try out that unit as well (uses phantom power as power sourse rather than the wall transformer ofthis unit).

    Again, I own several quality pre amps with DI. The difference in guitar DI sound using this unit as compared to my expensive preamps, is nothing less than stunning. Truely a fantastic product.
    It has mulitple features. I am subtracting a point, because I have not been able to convince myself that these additional features lead to a better sound. Solid.
    A solid quality product from Radial.
    I wish that quality was less expensive.
