The Wampler TCD Drive (The Compulsion Drive) emerges as a meticulously engineered homage to a modern classic: the legendary Fulltone OCD. Driven by Brian Wampler’s obsessive attention to detail, this pedal seeks to refine and expand upon the iconic circuit’s beloved roar, sparkle, and dynamic response.
While instantly familiar, the TCD introduces key upgrades for the modern player. A powerful three-band EQ grants precise control over the midrange and frequency spectrum—an answer to a common desire for greater sculpting within the original architecture. A front-panel Mode switch offers two distinct gain personalities:
- the traditional circuit character or
- a more aggressive, cascaded MOSFET voicing for a harder-hitting, tube-like saturation.
True to Wampler’s boutique philosophy, the TCD’s customizability runs deep. Internal DIP switches unlock further tonal archetypes: a Fat switch adds foundational low-end warmth, while a Diode switch introduces an extra clipping stage for tighter, more saturated distortion. This allows players to dial in everything from the classic, dynamic overdrive to a thick, high-gain foundation, making the TCD not just a tribute, but a significant evolution of a legendary sound.
