When I need to add depth and warmth to an overly clean source, I can count on my Burl B1D. It's an amazing bass DI/preamp, and when I drive this transformer-based preamp into its sweet spot, it sounds like an old console pushed to its limits. Paired with a ribbon mic, the B1D works great for amps, and I get huge 3-dimensional guitar tones when use it alongside neve-style preamps.
Buy This Pre
I have used multiple 500 series units and have other top notch press, This thing really has one of the warmest sounds I have ever heard especially on guits and bass. It is also fantastic on vocals (especially if you add a little compression).
Could not be happier with this purchase!!!
Our secret weapon
This has been my little secret for awhile now but others need to know: this Pre sounds phenomenal! We tested it thoroughly against the API 512c and UA 610 and, though they both sound great, there was a clarity and vibe to the Burl tracks that brought our tracks to the next level. If you haven't converted to Burl, don't hesitate!
