The Compulsion Drive (tcd) is Brian Wampler’s obsessive reinterpretation of one of the most legendary distortion circuits in the history of modern guitar pedals. Designed to deliver the unparalleled roar, sparkle, and dynamic sensitivity so sought after by guitarists, the tcd combines raw power with refined tonal sculpting. Whether you are looking for a precise crunch, harmonically rich saturation, or punchy solos, the tcd puts everything within reach thanks to intuitive controls and Wampler’s signature attention to detail.
A three-band EQ finally lets you achieve the sound you desire from this circuit. The mode selector offers you a choice between two types of saturation: in the low position, a traditional gain structure; in the high position, a more incisive and warm sound, similar to that of tube amps, thanks to cascaded MOSFET gain stages. The Compulsion Drive holds even more sound-shaping possibilities.
One of the key features of the tcd is its ability to tap into the classic tones of the original circuit that inspired it. Two internal DIP switches allow you to shape the pedal to your preferences. The Fat switch adds warmth and deep bass for a richer sound, while the Diode switch modifies the gain profile via an additional clipping diode, for a more precise and saturated distortion. These discreet options give the tcd customization worthy of boutique pedals and exceptional versatility.
The spirit of distortion
At the heart of the tcd is a circuit long recognized for its harmonic complexity and amp-like response. The Compulsion Drive comes alive under your fingers: a clean sound transforms into a shimmering crunch when you ease off the controls, and an explosive distortion is unleashed when you attack the strings. It is the type of pedal that reacts like an amp, and it is already a staple on the Wampler team's pedalboards.

Timeless circuits, total control
The gain control allows you to achieve a wide sonic palette, from a light crunch to a roaring distortion. Sculpt your sound with the powerful three-band EQ (Bass, Mids, and Treble), which gives you a tonal range from precise and incisive saturation to full-bodied sounds with exceptional clarity and presence. Finally, the level control allows you to adjust the output to your needs, whether you want to push your amp to the limit or achieve a perfect balance in the mix.
Responsiveness, power, and bite
What sets the Compulsion Drive apart is its ability to blend harmoniously with your amp, much more than a simple effect pedal. It enriches the harmonic content of your signal, allowing chords to shine brightly and notes to sing with sustain and definition. Paired with other pedals, it reveals unprecedented sonic nuances and harmonic richness.
