Mercuriall AMPBOX

Mercuriall AMPBOX is a conceptual software guitar processing suite engineered as a comprehensive, modular environment that provides guitarists and producers with a full virtual rig of meticulously modeled amplifiers, cabinets, and effects.¹ Moving beyond static emulations, AMPBOX utilizes a proprietary Neural Hybrid Engine (NHE) to blend circuit-level modeling with deep learning technology, capturing the dynamic interaction and non-linear response of tube circuits with unparalleled fidelity. It is the definitive digital solution for crafting nuanced, responsive clean tones, dynamic blues grit, and crushing modern high-gain sounds.

The Architecture of Hybrid Emulation

The core strength of AMPBOX lies in its dual-technology approach to capturing the electric guitar signal chain:

• Neural Hybrid Engine (NHE): The amplifier models within AMPBOX are powered by the NHE.² This system employs traditional circuit-level modeling to capture the core signal path—preamp stages, tube biasing, and power amp dynamics—while simultaneously leveraging neural networks to accurately reproduce the subtle, non-linear behavior of transformers and speakers under load. This hybrid method ensures the digital models react to the player's attack and guitar volume with the harmonic complexity and sag of authentic analog hardware.

• Component-Level Customization: The suite offers deep customization capabilities at the component level. Users can swap virtual Power Tubes (e.g., $6 \text{ L}6 \text{ s}$, $E \text{ L}34 \text{ s}$), adjust the Bias voltage, and control the Sag (power supply compression) of the power stage. This level of granular control allows the user to tailor the core feel and response of the amplifier to match various tones, from vintage warmth to modern tightness.

The Modular Signal Path

AMPBOX is designed as a flexible modular environment, allowing users to build and reorder their signal chain easily:

• Integrated Stompbox Section: A comprehensive library of classic and modern stompbox effects is included. These are modeled to be placed pre-amp, allowing the user to drive the amp model with accurate digital recreations of legendary overdrive, distortion, boost, and fuzz pedals.

• Dual Cab & Impulse Response (IR) Loader: The Cabinet Section is robust, featuring both a collection of meticulously captured virtual speaker cabinets and an advanced, dual-loading Impulse Response engine. This allows the user to blend the sonic characteristics of two different cabinets and microphone placements simultaneously, creating enormous, mix-ready stereo guitar tones.

• Rack Effects: Post-amp processing includes high-fidelity rack effects such as time-based modulation (chorus, flanger), dual delays, and studio-grade reverb, completing the entire virtual signal chain within one instance of the plugin.

Versatility and Workflow

Mercuriall AMPBOX is built for professional studio work, offering low-latency performance and a streamlined, visually intuitive workflow.³ It provides the depth of an entire collection of prized hardware rigs in a single, CPU-efficient software environment, making it the essential tool for modern guitar production.
