Do you know about Guitarix, my fellow guitarists? It’s not a type of movie or someone’s imaginary friend. In fact, it’s a software application for Linux that can transform your electric guitar-playing experience.
Guitarix is a virtual guitar amplifier that works exclusively with Linux and requires the Jack Audio Connection Kit tool. It’s free, open-source, and functions like a real amp by processing your guitar’s mono signal from your sound card.

Then it’s processed for the first time by Guitarix, which can then pass it through a rack. This rack can be embellished with modules that then allow you to apply effects to the sound of your guitar, such as a noise gate, a phaser, a flanger, etc.
Here’s what it looks like on video:
In terms of latency, Guitarix performs well and can provide a delay of under 10 milliseconds, although this can vary depending on your machine’s specifications.
If you’re interested in trying Guitarix, you can find more information on their website. Additionally, there is a tutorial available that doesn’t use any words to guide you through the setup process.
