Dual-Channel Vacuum Tube Microphone Preamp and DI Handbuilt in the US

Building on the legacy and design philosophy of the legendary D.W. Fearn and crafted by Hazelrigg Industries.

Pure Tube Signal

VDP is a handcrafted, two-channel preamp and DI featuring an all-tube signal path and transformer-coupled input and output stage, adding natural harmonic depth and musicality. Drawing from the acclaimed tube preamp and power design of the D.W. Fearn VT series, VDP brings the signature character and tonal richness of the vintage classic, paired with cleaner headroom, lower noise, and modern reliability.

The Definitive Input Stage

An intuitive front end with a world-class tube stage to enhance any source and to complement all microphones. With +6bs of gain more than the VLC and DWF VT-2, the VDP offers higher headroom, more saturation, and a nuanced flavor unique to the DWF Hazelrigg lineup. 

Clean gain for ribbons, articulate for condensers, and deep headroom for your loudest dynamics.

DWF Hazelrigg VDP | Handcrafted Two-Channel Tube Preamp & DI
Pure Tube Signal. Definitive Character.

The VDP is a premium two-channel preamp and DI designed for the modern studio that demands the soul of vintage vacuum tubes without the compromises of legacy noise floors. Handcrafted in the USA, the VDP combines an all-tube signal path with transformer-coupled inputs and outputs to deliver natural harmonic depth, musical saturation, and a polished sheen.

The D.W. Fearn Heritage, Refined

Drawing its DNA from the legendary D.W. Fearn VT series, the VDP is rooted in the acclaimed preamp and power design that shaped decades of hit records. However, the VDP stands on its own: offering its a unique flavor, higher gain and more saturation than the VT-2, and providing a nuanced "shine" and articulate detail unique to the Hazelrigg lineup.
