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.
CharBooster is available as a
freeware VST effect plug-in for Windows (32/64-bit).
