The Studio Rats - Testing DI Boxes

In this video Paul and James take a look three different DI (Direct Injection) boxes for recording bass.
DI boxes are far from what you might call sexy pieces of studio kit but most, if not all of us have at least one and as it turns out, not all DI boxes are created equal.
The three models under test are the Warm Audio Active DI (thanks to Nova Distribution in the UK for this one). The MTR DI-3 and the Behringer Ultra-DI DI-20.
Three different units at three different price points. Let us know which one you prefer.
The Studio Rats are core band members Paul Drew on guitar/production/mixing, drummer James Ivey and Dan Hawkins on bass. They collaborate with singers and musicians to produce radio-ready songs.
