Hazelrigg Industries DLC 500 Vacuum Tube Inductor Equalizer - Vintage Tone, Modern Precision
This is the stereo pair listing.
The Hazelrigg Industries DLC 500 Vacuum Tube Inductor Equalizer brings classic tube warmth and sophisticated tonal shaping to your 500-series rack. Derived from the passive EQ circuit of the Hazelrigg VLC—originally inspired by the D.W. Fearn VT-5—this module blends vintage-inspired design with modern reliability. Featuring the same filter capacitors and hand-wound inductor as the VLC, the DLC offers a slightly unique audio path with a vacuum tube input stage from the D.W. Fearn VT-2 and a low-THD, high-gain solid-state output amplifier. Transformer-coupled input and output stages ensure rich, harmonic-laden sound, making it a standout choice for studio engineers and musicians.
Musical EQ with Intuitive Control
Designed by D.W. Fearn, the DLC delivers versatile equalization with a vacuum tube input stage (6072a) that imparts analog warmth to any source. Its passive EQ circuit includes High Cut, High Boost, Low Boost, and Low Cut controls, each paired with frequency select switches for precise sculpting. Boost and cut simultaneously to craft complex EQ curves—start by maxing all controls except the bass boost, adjust frequencies to taste, then dial in the bass boost for a balanced, dynamic sound.
Built for Studio Excellence
Handcrafted in the USA, the DLC combines premium components—like its hand-wound inductor and transformers—with a robust 7-year warranty (90 days for vacuum tubes). Whether you’re shaping vocals, guitars, or full mixes, this equalizer offers the flexibility of a front-panel microphone/instrument input and a bypass switch for instant A/B comparisons, all in a compact 500-series format.
