I have an old DOD direct box and a LiveWire direct box that I use for recording bass and sometimes a DI track for guitars. Nothing sexy about them. They do what a DI should do. I also see the Radial DI's and such selling for major dollars and scratch my head wondering what justifies that cost? The more I experiment with bass sounds in the studio the more I find a clean DI track from either DI being an important piece in getting a killer sounding track. I am truly not understanding what I am paying for in those more expensive units.
