Handbuilt Tube Performance for Modern Studios
The Hazelrigg Industries VDP Dual-Channel Tube Preamp and DI is a premium, handbuilt input stage designed for professional studios that demand the unmistakable character of vacuum tubes with modern performance and reliability. Built in the United States and rooted in the design philosophy of D.W. Fearn, the VDP carries forward the sonic legacy of the revered VT series while refining it with increased headroom, lower noise, and enhanced versatility for today’s recording workflows.
All-Tube Signal Path with Transformer Character
At its core, the VDP features a fully tube-based signal path with transformer-coupled inputs and outputs, delivering natural harmonic depth, musical saturation, and polished high-end clarity. Whether you're tracking vocals, instruments, or line-level sources, the VDP provides a rich, dimensional tone that elevates any signal, while maintaining transparency and control. Compared to earlier designs, it offers increased gain and headroom, allowing it to handle everything from delicate ribbon microphones to high-SPL sources with ease.
Flexible Dual-Channel Front End for Any Source
Designed as both a microphone preamp and DI, the VDP serves as a flexible front end for modern studios. Its intuitive layout includes front-panel Mic and DI inputs for quick instrument tracking, while rear XLR connections support permanent studio integration. With up to +63 dB of gain, it delivers clean amplification for gain-hungry microphones alongside the ability to introduce tasteful tube saturation when desired.
Precision Controls and Studio-Ready Features
The VDP is engineered for precision and reliability in demanding recording environments. A switchable 20 dB input pad and integrated high-pass filter allow for careful gain staging, while a polarity reversal switch ensures proper phase alignment in multi-mic setups. A regulated +48V phantom power supply, secured with an aircraft-inspired locking switch, provides safe operation for condenser microphones. Internal fully regulated solid-state power supplies for filament, phantom, and B+ voltages ensure consistent performance, while premium components like a conductive plastic attenuation control guarantee long-term noise-free operation.
Handcrafted Quality with Lasting Reliability
Not mass-produced, each VDP unit is meticulously handcrafted, tested, and auditioned before leaving the workshop. The result is a dual-channel tube preamp and DI that combines vintage-inspired tone with modern clarity, built to serve as a reliable and sonically superior centerpiece in any professional recording chain.
