Project overview

The Celeritas Organic Overdrive is based on the Greer Lightspeed, first released in 2013.

The Lightspeed is a stripped-down transparent overdrive inspired by circuits like the Timmy and Zendrive. The input clipping stage is the same topology as the Tube Screamer, with soft clipping diodes in the feedback loop of the op-amp. This is followed by gain recovery and passive tone shaping that has some resemblance to the OCD, including a treble cut control at the end of the circuit.

While not terribly innovative, the Lightspeed circuit is very carefully tuned and has earned its spot on the pedalboards of many A-list musicians.

The Celeritas is a straightforward adaptation with no modifications other than some tweaks to the power supply for consistency with other Aion FX projects.
