Features
Filtering and saturation
Set which frequencies reach the amplifier, then adjust Drive to add saturation. Automatic gain compensation counteracts the added level. Shape the speaker emulation with size, fidelity and presence controls. Use Dynamics to restore movement reduced by saturation, and Residue Mix to bring filtered frequencies back after the effect chain.
These images show detail controls from the full edition.
Mix, stereo and modulation
Blend the processed signal with the original using Wet Mix. Work in stereo or mid/side, use Balance for different saturation between channels, and add variation with Flux. The Mix Designer sets its rate, character and stereo spread.
