AXP has announced the release of CharBooster, a free guitar booster/overdrive effect plug-in for Windows.

AXP CharBooster

The CharBooster is based on the 12ax7 tube preamp and the ATR-102 tape recorder models.

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).
