Project overview

The Titan Dynamic Drive is an adaptation of the legendary Fulltone® OCD®. The Obsessive Compulsive Drive was first released in 2005, itself a modified version of the Voodoo Labs Overdrive with several added features and tweaks.

There were seven different official versions of V1 from its initial release until it was replaced by the V2 in 2017. Prior to the release of the “true” V2, these versions were referred to by the gear community as V1, V2, V3, etc., but they’ve always been labeled V1.1, V1.2, V1.3, etc. inside the enclosure.

For this project, we’ve brought in the most noticeable circuit tweaks from V1.1 through V1.7 and using DIP switches to make them configurable. The result is a tonal workstation, allowing you to tailor your own perfect version of the circuit.

We’ve included extensive documentation on the major differences between the versions and the switch combinations that correspond most closely to each. The default parts list corresponds to v1.7, which is the version that was in production the longest with around ~75,000 units manufactured.
