Black Box Analog Design – HG-2

The HG-2 is a premium analog saturation and harmonic generation processor designed for modern studios that demand character, depth, and control. Built around authentic tube and solid-state circuitry, the HG-2 delivers rich harmonics, subtle warmth, or aggressive drive while preserving clarity and punch. It is equally at home on individual tracks, subgroups, and full mixes.

At the heart of the HG-2 is a flexible dual-stage harmonic engine that allows you to blend parallel saturation paths, sculpt tone with precision filtering, and enhance perceived loudness without sacrificing musicality. From subtle analog polish to bold coloration, the HG-2 brings depth, energy, and dimension to any signal.

Key Features

• Dual Harmonic Generators

  Independent Pentode (odd-order harmonics) and Triode (even-order harmonics) circuits for flexible tonal shaping.

• Parallel Saturation Architecture

  Blend saturation paths in parallel to maintain transient clarity and low-end integrity.

• Air Band Enhancer

  Adds smooth high-frequency presence and openness without harshness.

• Dynamic Saturation Control

  Drive harmonics harder while retaining mix balance and punch.

• High-Pass and Low-Pass Filtering

  Shape which frequencies are affected by saturation for precise tonal control.

• Mid/Side Processing

  Independently process the mid and side signals for advanced stereo imaging and mix enhancement.
