CharBooster is a composite overdrive effect tailored specifically to be used as booster in front of any virtual amplifier model. It essentially consists of a pre-emphasis filter section designed to provide a variation of voicings for your instrument followed by a saturation circuit that excites the signal with harmonics while still being as transparent as possible. The UI is not trying to look like a hardware stomp box but rather has a range of meters and scopes to provide an insight on what is going on with your signal.
The tube model used in the saturation stage is similar to the one used in Softamp 3OD, however the modeled circuit is different. The tape model is a very simplified one. It has only the nonlinear transfer curve and dynamic frequency response modeled. Wow & flutter effects as well as phase smearing were omitted keep the CPU consumption low. It is loosely based on the Ampex ATR-102 tape recorder.
