Tube Amp simulates a microphone preamp with a 12AX7 vacuum tube. The plugin delivers asymmetric tube triode overdrive with an additional saturation stage on the output. It uses 8x oversampling to ensure aliasing-free harmonic distortion.
You can use Tube Amp for enhancing audio recordings or as a coloring tool for virtual instruments. Add a bit of tube-style saturation to enhance the sound of digital synthesizers and sample-based instrument plugins. The plugin supports stereo and mid-side processing, as well as channel grouping.
Like most Voxengo plugins, Tube Amp offers full undo/redo history, A/B comparison functionality, and a built-in preset manager for saving and loading custom settings. The developer also included hints for each control parameter, helping new users get familiar with the workflow.
It’s worth noting the Tube Amp supports all sample rates and zero-latency processing. It works quite well as a saturation plugin for tracking and for use during a live performance.
Here’s how Voxengo describes the Tube Amp plugin:
“Tube Amp is a free audio effect plugin that applies asymmetric tube triode overdrive usually found in single-tube microphone pre-amp boxes. The sound this plug-in produces varies from a mild “warm” overdrive to a fuzzy distortion.”
