Wampler TCD Distortion – analog drive with classic OCD character and modern tone control
The Wampler TCD Distortion (The Compulsion Drive) is an analog overdrive/distortion designed by Brian Wampler as a refined interpretation of one of the most influential drive circuits in modern pedal history. It delivers an amp-like feel with high dynamics, clear articulation, and a wide tonal range that covers everything from light breakup to full-throated distortion.
Overview and Features
The TCD combines a classic OCD-inspired topology with Wampler’s modern engineering approach. Its three-band EQ (Bass, Mids, Treble) provides extensive tone shaping, while the Gain control spans from edge-of-breakup grit to fully saturated rock and lead tones. A two-position Mode switch alters the clipping structure from traditional to a harder-hitting, tube-like MOSFET response.
Construction and Components
The pedal uses high-quality analog components built around an enhanced OCD-style circuit. Internal DIP switches offer deeper tone customization: a Fat mode for added low-end weight, and a Diode mode that shifts the gain profile toward tighter, more saturated distortion.
Connectivity and Integration
The TCD is a mono pedal with standard instrument-level input and output. True bypass ensures that the signal remains unaffected when the pedal is bypassed.
Control and Workflow
The controls include Level, Gain, and a full three-band EQ. The Mode switch provides two clipping flavors, while internal DIP switches offer additional shaping. The pedal responds dynamically to picking strength and your guitar’s volume control, enabling everything from clean tones to heavy drive without changing settings.
Technical Depth – Format, Standards and Requirements
Format and Standards
The compact enclosure (64 × 125 × 60 mm) fits easily into most pedalboard configurations.
Power Requirements
Powered by 9–18 V DC (center-negative). Current draw is 20–25 mA. Battery operation is not specified.
Environment and Application
Suitable for both studio and live use, the TCD behaves more like an extension of the amp than a conventional distortion pedal, enhancing both harmonic content and dynamics.

FAQ
What differentiates the Wampler TCD from a traditional OCD circuit?
The TCD retains the core character of the classic circuit but expands tonal flexibility with a three-band EQ, two clipping modes, and internal DIP switches.
Can the pedal run at 18 V for increased headroom?
Yes. It supports 9–18 V DC operation, and using 18 V increases headroom and dynamic response.
Does the pedal clean up well using the guitar’s volume control?
Yes. The design responds like an amplifier and reacts clearly to volume adjustments and playing dynamics.
Is the pedal suitable for both rhythm and lead playing?
Yes. The wide gain range and flexible EQ make it well-suited for tight rhythm work and saturated lead tones.
