Wampler tcd (The Compulsion Drive)

Wampler's tcd is a modern, obsessive reimagining of one of the most legendary distortion circuits in guitar history—a heavily modified, MOSFET-driven analog foundation that delivers massive punch and unmistakable growl. It's engineered to be a versatile workhorse, capable of producing everything from articulate, edge-of-breakup grit to harmonically rich, searing saturation. Crucially, the tcd offers an incredibly dynamic, amp-like feel, cleaning up beautifully when you roll back your guitar's volume and exploding into blooming harmonics when you dig in, making it feel like a natural extension of your amplifier.

Tonal control is unmatched thanks to the highly effective three-band EQ for Bass, Mids, and Treble, which allows you to perfectly sculpt your sound to fit any rig or mix. The external Mode switch is your portal to two distinct clipping flavors: one for a traditional gain structure, and the other utilizing cascaded MOSFET stages for a harder-hitting, tube-like response. For the truly dedicated tone sculptor, Wampler included two internal DIP switches (Fat and Diode) that unlock four classic circuit variations, allowing for boutique-level customization. Housed in a premium sparkle platinum enclosure and built in the U.S.A. with high-grade components, the tcd is ready to deliver professional tone and reliability for years to come.
