Inversion Drive

GT original overdrive and fuzz design

 

 

The Inversion Drive overdrive rack effect module is a GT original design based on CMOS inverter chip technology.  These chips can provide some nice tubey, crunchy/buzzy overdrive that responds well to your guitar volume.  Other effects that use inverters and are roughly comparable include the Way Huge Red Llama and Emma Electronic ReezaFRATzitz.

 

Description

The Inversion Drive is an original GT design that comes in two configurations.  The Inversion Drive is a medium overdrive.  The Inversion Fuzz is a lower-gain fuzz, which can be dialed back to overdrive territory.  

Both produce their distortion using an inverter chip, similar to the Way Huge Red Llama, Emma Electronic ReezaFRATzitz, the Craig Anderton Tube Sound Fuzz, and other similar overdrives, distortions, and fuzzes.  This type of distortion is considered more tubey than some other types.  At low gain levels, you get a cleanish boost you can use to push a cranked tube amp into overdrive.  At higher drive levels, you get distortion that varies with pick attack and cleans up with your guitar volume. Both also feature active Bass and Treble controls.  A Bias option controls the headroom through the inverter chip, allowing cleaner or dirtier tones.  It is subtle in the Drive and more pronounced in the Fuzz.

The difference between the two modules is that the Fuzz has a bit more distortion available than the Drive.  But the Fuzz is not a high-gain, ripping fuzz.  It is a lower gain fuzz, more of a Drive Plus than a full-out fuzz.  The Drive also has a subtle Voice switch which either leaves the tone intact or cuts at one of two different points in the midrange.
