01Overview

Tube Shelf is an EQ plugin that models the characteristics of a well-known tube program equalizer. Its module is mainly used to adjust low and high frequencies, with relatively few frequency band options. The developer positions it as a tool for bringing the unique tonal coloration of the original hardware into a digital session. It is built on APNN 2.0 neural modeling and is part of the Deep Vintage Suite.

03In depth

Sound and Character of the Tube Shelf EQ

Three-Body Technology describes Tube Shelf as a faithful emulation of the tonal coloration of its hardware counterpart. The plugin is built on APNN 2.0, a neural network trained on the original hardware by feeding both the same audio and learning how the hardware changes it in the waveform and spectrum. The developer says this allows the model to capture both the dynamic and tonal character of the source unit.

The goal is a smooth and natural sound rather than a clinical one. Because the module offers a limited set of frequency bands, it is often used alongside other EQs for more detailed shaping.

Controls, Workflow and Processing Options

Tube Shelf includes practical tools for everyday mixing, including undo/redo, A/B switching, an input/output level meter, mono mode, LR/MS processing, phase invert and GUI re-scaling. These make it easier to compare settings and work with stereo or mid-side material.

The plugin is available in VST3, VST2, AU and AAX formats for Windows and macOS, and it is part of the Deep Vintage Suite, which the developer describes as having low CPU impact.
