Hazelrigg Industries VDI Single Channel Tube Direct Box From Hazelrigg
The VDI is a single-channel, all-triode vacuum tube DI (“direct box”) for recording electric or electronic instruments. The inputs are designed to provide the proper load impedance for all instruments that have a 1/4-inch phone jack output. Tube circuitry provides the very high impedance necessary to capture all the details of these instruments.

Manufacturer's Description from Hazelrigg
A reimagining of the legendary D.W. Fearn VT-1/F, the VDI is an all-triode Vacuum Tube Direct Box in a single channel configuration. Unlike the original VT-I/F dual channel design, the VDI is a single channel offering housed in a robust, low profile steel chassis, ready to slip into a backpack or gig bag. Designed for both stage and studio work, the VDI is offered as part of the Hazelrigg Industries Solutions Series by D.W. Fearn and will deliver incredible results with amplified acoustic instruments, electric bass and guitar, synths or more.
The operation is simple as can be. The front panel includes a 1/4” Instrument Input jack as well as a 1/4” Thru connector to pass the signal on to a guitar or bass amplifier if desired. The mic level output signal is available on an XLR Connector, ready to be patched to a premium Microphone Preamp such as the D.W. Fearn VT-1, VT-2, VT-24 or Hazelrigg Industries VLC. Finally a Ground Lift option is provided to address Ground Loop issues should they arise. The more utilitarian rear panel features an IEC Mains Socket, Power Switch and 115V-220V Mains Selector.
Sharing the same high-headroom circuit design as the venerable VT-I/F, the VDI will provide stunningly dynamic results on electric bass and guitar, add power and girth to vintage (or modern!) synths and bring a depth and realism to piezo equipped acoustic instruments outfitted that simply must be heard.

About Manufacturer
With backgrounds in live performance and production, brothers Geoff Hazelrigg and George Hazelrigg approach the design and manufacturing of studio equipment from the perspective of the artists, with a deep understanding of the goals and challenges they face.
While the Hazelrigg Brothers often work in beautifully outfitted studios (or truck racks of gear into less well-equipped venues), they found that many of their colleagues were facing very different obstacles. With changes in production methods, more and more tracks were being cut in bedrooms and hotel rooms, on headphones or unfamiliar monitor systems, with the resulting audio showing the marks of these inconsistencies.
Hazelrigg Industries addresses these challenges by hand crafting recording equipment which not only delivers superlative sonics but also allows engineers and producers to work quickly, efficiently, and - most importantly - musically to achieve their goals at the highest levels.
