Woctavia is a software plug-in effect. It is an octave doubling fuzz effect which has been specifically designed to recreate the sound of the famous Tycobrahe Octavia guitar effects pedal.
Octave doubling fuzz is unique among distortion effects. Due to the way the signal is modified, there is a frequency doubling effect. It's fame in the guitar world is most likely due to its use by Jimi Hendrix, and it can be heard in his solos on such songs as "Purple Haze" and "Fire." The applications of octave doubling fuzz, however, reach well outside the world of guitar music.
An octavia pedal can sound very different depending on the input signal. They are very reactive to variations in playing style. Wire Grind performed detailed analysis on an authentic Tycobrahe Octavia pedal. They have pinpointed, precisely, what gives this pedal its strong character. Rather than a simple full-wave rectifier, the pedal transforms the signal in a dynamic and complex way. It is an effect that can't be recreated by a simple waveshaper. In Wire Grind's effect algorithm, they have had great success duplicating the characteristics of the analog pedal.
Woctavia includes a feature referred to as "anti-aliasing". This feature uses oversampling to produce higher quality sound. In addition to the classic model, Wire Grind has added a special processing mode called "Warmth". This mode provides an enhancement of the original effect's tonal qualities. It essentially uses an idealized model, and thereby creates a softer, less buzzy sound.
