Sigma v2

What is Sigma v2?

Sigma v2 is a guitar amp simulation plugin designed for musicians, producers, and home studio users who want modern high-gain electric guitar tones inside a DAW. It is published by Audio Assault and offered as part of the company’s amp simulation lineup. The plugin focuses on amp-style tone shaping for rhythm, lead, and heavier distorted sounds, making it useful for songwriting, tracking demos, reamping, and mix production. Users can load it in supported audio software to build guitar tones without miking a physical amplifier, which is especially helpful for quiet recording setups and fast preset-based workflows. Sigma is also connected to Audio Assault’s Amp Locker ecosystem, where compatible amp sims can be managed and used together.

Key features

• Shape tones with a three-channel high-gain amp simulation
• Create clean, crunch, and lead-style guitar sounds in a DAW
• Adjust gain and tone controls to refine low and high frequency response
• Use built-in amp simulation for recording, demo production, and reamping
• Work with Audio Assault's Amp Locker environment for compatible amp workflows

Safety overview

Status: Mostly safe

Sigma v2 is ordinary music production software. It typically works inside a DAW and uses normal access to audio processing resources, presets, and plugin-related files. Removing it can make projects open with missing plugin instances or changed guitar tones, so keep it installed if older sessions still rely on it. Download updates and installers from Audio Assault to reduce the chance of compatibility or stability problems.

Recommendation: Keep Sigma v2 if you use it for guitar recording or may reopen projects that depend on its presets and amp tones. If you no longer use it and do not need past sessions to sound the same, you can remove it along with its support files.
