I've been using a couple models of SNE's DI as well as their instrument and patch cables since I met with Ted Burmas at NAMM this year, and I couldn't have been happier to be asked to partner with a cooler, more responsive, customer-focused outfit.
The TDI is transformer based using a Jensen transformer, and features one of the most accurate and stable built in tuners for bass I've ever used. It actually tracks and reads the open low B string, and well! It's extremely high grade, transparent, rugged gear. It doesn't impart its own sonic character if you're looking for that, but if faithful reproduction and signal balancing is what you're after, you'd be hard pressed to do better.
Thank you very much Ted and Sonic Nuance Electronics, I'm honored to work with you and very happy to help represent your excellent products!! - Sean Fairchild
