Audio Assault Sigma 1.02 for Mac
Mac AudioAudio Assault Sigma 1.02 for Mac, styled SI6MA, is a guitar amp simulation plugin built for heavy tones. Audio Assault modelled it on an acclaimed high-gain amplifier, and it is aimed squarely at rock and metal players who record direct into a DAW.
Around the amp itself you get the tools a high-gain rig needs: a noise gate to keep tight riffs clean, a screamer-style drive in front, a 3-band EQ, and power amp saturation for pushing the sound harder. It also loads speaker cabinet responses, so a DI guitar can sound like a recorded amp without a microphone in sight.

- Built-in noise gate and screamer-style boost for tight, focused riffs

FAQs
Is Audio Assault Sigma free?
Sigma was released as a free plugin when it launched, which is rare for a full amp sim. Availability can change as Audio Assault reorganises its store, so check the official site.
Do I need Amp Locker to use Sigma?
No. Sigma is a standalone plugin from before the Amp Locker platform became the centre of Audio Assault's range, so it loads directly in your DAW.
