Sonic Nuance Electronics Introduces the TDI Mk2

Sonic Nuance TDI Mk2 Direct BoxSonic Nuance has introduced the TDI Mk2, a direct box that combines tuner and DI functions. The new pedal retains the signal path from the Mk1 version but has a more accurate and stable tuning section, the company says.

At the heart of the TDI is a passive Jensen JT-DBE transformer. The chromatic tuner is phantom powered and fully operational even with a true lift between the XLR’s pin 1 and ground. Sonic Nuance says the frequency response of the pedal is 20Hz to 20kHz, allowing the tuner to respond to a low B string with ease. A footswitch allows for mute functionality.

The Sonic Nuance is hand assembled, designed and tested in the USA. It’s available now with a MSRP of $350 and a special introductory price of $330.

  1. Thanks NoTreble for posting this. I just wanted to emphasize that there is no need for batteries or a power supply with this. My design goal was to make a unit that allowed my sound to go through unaltered (hence the Jensen transformer) and in tune while NOT needing batteries or a wall wart. It turned out to be a challenge!
