Extremist is a multi-effect plug-in designed for use with guitars - its main purpose is for distorting a guitar signal to create an "extremely heavy sound". This effect is not a tube amplifier simulator, however some methods of altering the signal are similar to tube amplification characteristics.

Extremist works in stereo, without any latency, and includes a 15-band stereo equalizer. It uses SSE instructions for Pentium II or newer CPUs.

Controls:

• Drive, Dry, Wet, Volume: knobs for regulating amplification & mixing signals.
• Feedback: level of feedback signal.
• Clip: clipping level.
• Reverb: stereo reverb effect, adjustable up to delay.
• Mod Boost: mid-tones amplification.
• Eq Q: width of each frequency band amplification of equalizer.
• Pre HPF: filtering low frequencies of effect input.
• Post LPF: filtering of high frequencies of effect output.
• Noise gate.
• Amp curve: amplification characteristic.
• Lock bars: steering of equalizer in mono/stereo.
• Post gating: noise gate applied before/after effect.
• Smoothing: signal smoothing (hiss reduction).
