The Wampler tcd (The Compulsion Drive) overdrive pedal reimagines one of the most iconic overdrive circuits of the last two decades, pairing Brian Wampler’s refined OCD-inspired architecture with a level of control the originals never offered. Designed to feel responsive and “amp-right,” it delivers everything from open, edge-of-breakup crunch to thick, high-gain distortion that blooms with harmonics and tracks your picking dynamics in real time. A full three-band EQ—Bass, Mids, and Treble—makes the tcd exceptionally adaptable across guitars, amps, and genres, while a clipping Mode switch and internal DIP controls allow you to tailor its voice from vintage grain to tighter, more modern saturation. Handbuilt in the USA with touring-grade components, it’s a compact, expressive overdrive that brings classic soul and modern flexibility together in one stage-ready design.
Refined Circuit With Dynamic, Amp-Like Response
Built on Wampler’s modernized interpretation of the revered OCD lineage, the tcd uses carefully tuned MOSFET-based gain stages to deliver a responsive, harmonically rich drive that reacts instantly to touch and volume changes. The pedal stays articulate when you play lightly and roars with controlled aggression when you dig in, offering a punchy low end, expressive mids and a natural top end that avoids the harshness often found in hard-clipping designs. This refined approach gives players the feel of a pushed tube amp—tight when needed, open when desired, always musical.
Expanded Tone Shaping With Three-Band EQ and Flexible Clipping
The Compulsion Drive stands apart with its three-band EQ, letting players sculpt low-end punch, midrange presence and high-end bite with far more precision than fixed-voicing overdrives. A front-panel Mode switch toggles between classic clipping and a more forceful cascaded MOSFET structure for added girth and saturation. Inside, two DIP switches provide deeper customization—a Fat option for enhanced low-frequency weight and a Diode option that tightens the response for a more modern, focused grind. Together, these controls help the tcd adapt seamlessly to single-coils, humbuckers, high-headroom amps or mid-pushed combos.
The Compulsion Drive: Set Your Tone into Overdrive
Handcrafted in the USA, the tcd features a rugged metal enclosure and premium components that stand up to years of travel and stage use. Its compact footprint slips easily onto crowded boards, while top-mounted jacks and intuitive controls make setup fast and performance reliable. Designed for players who rely on their overdrive as a core voice rather than a secondary flavor, The Compulsion Drive offers the versatility, durability and musical response needed for touring musicians, studio pros and tone shapers alike.
