Hi All, I'm planning to get a passive DI box for studio recording and possibly for live gigging with IEM in the future. The one I'm planning to buy is a Radial Pro passive DI for my active 5-string Jazz bass. Here is a my first question: In addition to the use of a DI box for bass recording and going direct into a mixing table, could you please tell me whether there would be any use for a passive DI box in combination with an amp head (Little Mark III) that already has a DI output? I have a Little Mark III and a 4x10 Markbass cabinet. I'm wondering whether a DI box would add anything soundwise combined with my amp head that already has a DI output. Can I sort of bypass the Little Marks III DI with an extra (external) DI box? If so, is there a difference in quality between the built-in DI of my amp head and a reasonably good passive DI box such as the Radial Pro passive DI for instance? Or would it be completely useless (for live gigging) to have a DI box if one already has a good amp head with a DI output like mine? In other words, is there any added value to having a passive DI box in addition to a Little Mark III on stage? Thanks a lot in advance for your help. I'm totally new into the live sound thing.
