Audio Assault Sigma EX v1.0.5-V.R

Audio Assault Sigma EX is a three-channel guitar amp simulator for producers and guitarists recording heavy riffs, tight rhythm parts and expressive leads. Its amp design combines modern high-gain character with vintage influences, aiming for an aggressive tone that retains playing dynamics and harmonic detail.

The signal chain starts with three stomp effects: a noise gate for controlling unwanted noise, a boost for shaping the guitar’s response and a drive for adding bite and focus. Each amp channel has its own controls, letting you adjust sounds independently. After the amp, a nine-band EQ, delay and reverb help place guitars in a mix or give lead lines more space.

For cabinet shaping, Sigma EX offers three 3D cabinets with two blendable microphones, plus high-pass and low-pass filtering. An integrated IR loader lets you load and mix cabinet impulse responses, with panning adjustments available in stereo mode. MIDI automation, double-tracking simulation, a tuner and a preset system round out the workflow. This Windows edition suits home-studio musicians seeking a flexible high-gain guitar recording setup.
