York Audio FDMN 412 M25-V30 is a large impulse response library capturing a Friedman-style 4×12 cabinet loaded with Celestion Greenback and Vintage 30 speakers, delivering mid-focused guitar tones and extensive mic-blending options for amp modelers and plugin-based guitar rigs.

A Friedman-Style 4×12 Cabinet Captured As A Large-Scale IR Library

York Audio FDMN 412 M25-V30 is a guitar cabinet impulse response pack based on a Friedman-style “Vintage” 4×12 cabinet loaded with a combination of Celestion G12M Greenback and Vintage 30 speakers. The pack focuses on delivering a bold, mid-forward cabinet tone designed to sit clearly in dense mixes, particularly for rock and modern high-gain guitar tones.

The speaker pairing defines the character of the library. Greenbacks contribute energetic attack and articulate midrange presence, while the Vintage 30 speakers introduce thicker low end and a darker, controlled high-frequency response. Together they produce a cabinet profile with strong low-mid body and focused mids rather than the scooped tonal shape often associated with modern metal cabinets.

A Hybrid Speaker Blend Designed For Midrange-Focused Guitar Tones

The tonal identity of the FDMN 412 pack comes from blending two historically popular speaker designs. The Greenback component provides clarity and upper-mid articulation that helps guitar parts cut through a mix, while the Vintage 30 component reinforces low-end depth and adds weight to distorted tones.

This combination produces a cabinet response that works well for lead tones, crunchy rhythm guitars, and modern rock gain structures, where midrange presence and controlled low-end thickness are critical for mix translation.

A Large IR Library With Extensive Mic And Blend Options

The FDMN 412 M25-V30 pack is one of the largest York Audio impulse response libraries, essentially combining two full cabinet capture sets into one product. Each speaker was captured extensively using multiple microphones and mix variations, resulting in 298 impulse responses in total.

The library includes:

• 126 single-mic captures for each speaker
• multi-mic mixes for Greenback and Vintage 30 speakers
• additional blended speaker mixes combining both drivers

Twelve microphones were used during the capture process, including dynamic, ribbon, and condenser models such as SM57 variants, MD421, Royer-style ribbons, and large-diaphragm condensers. Ambient room captures are also included to introduce natural spatial depth when needed.

Despite the large number of files, the pack includes curated Mix folders designed for quick tone selection without extensive mic blending, allowing players to access ready-to-use cabinet tones immediately.

Designed For Amp Modelers, Plugins, And Hardware IR Loaders

The impulse responses are delivered as 24-bit WAV files at 44.1 kHz, 48 kHz, and 96 kHz, making the pack compatible with most modern guitar modeling ecosystems. These include hardware units from Fractal Audio, Line 6, Kemper, and Strymon, as well as DAW-based amp simulation plugins.

All IR files are captured at 500 ms length for maximum resolution, with hardware devices automatically truncating the files to the format required by the specific device during import.

A Flexible Cabinet Profile For Modern Digital Guitar Rigs

The FDMN 412 M25-V30 pack targets guitarists using digital amp modeling systems who want a cabinet response with strong midrange definition and controlled low-end weight. The Greenback and Vintage 30 blend provides a versatile tonal foundation that works across multiple gain levels, from crunchy classic rock to saturated modern rhythm tones.

The large IR library, combined with curated mix presets, allows players to move from quick plug-and-play tones to deeper mic-level experimentation depending on the workflow.

Mix-Ready Midrange With Strong Low-End Body

York Audio FDMN 412 M25-V30 stands out for its hybrid speaker configuration and extensive capture library. The combination of Greenback articulation and Vintage 30 weight produces a cabinet response that emphasizes midrange presence and full low-mid body, giving guitar tones the density required for modern rock and metal mixes.

For players using amp simulators or digital modelers, the pack provides a flexible cabinet foundation with both immediate mix-ready tones and deeper mic-blending options.
