Keeley Electronics Tube Drive Twin Triode Dual Overdrive Pedal - Black

Two distinct overdrive voices give the Keeley Tube Drive Twin Triode Dual Overdrive pedal the flexibility to serve as a centerpiece for a wide range of gain sounds. One side delivers warm, touch-sensitive tube grit through a genuine high-voltage 12AX7 tube, while the other brings the punch, body and sustain of Keeley's Phat Mod circuit. Each channel provides independent Level and Tone controls, with Gain for the tube side and Drive for the Phat Mod side, allowing the two voices to run independently or stack together for thicker overdrive textures. Switchable effect order and selectable true-bypass or silent buffered switching add flexible routing options, while the black enclosure proudly displays the Keeley-branded tube behind a custom shield.

High-Voltage 12AX7 Tube and Phat Mod Drive

The pedal's tube channel centers on a premium Keeley-branded 12AX7 operating at 168V for genuine high-voltage tube performance. Each tube is carefully burned in and fully tested, then paired with dedicated Level, Gain and Tone controls for shaping everything from warm, responsive grit to more saturated overdrive. Alongside it, Keeley's Phat Mod circuit provides a second drive voice with independent Level, Drive and Tone controls. Either channel can operate on its own, or both can be engaged together for thick, stacked overdrive tones, giving players two distinct gain stages within a single pedal.

Switchable Effect Order and Flexible Bypass Options

A simple footswitch gesture lets players reverse the internal signal path, choosing Tube into Drive or Drive into Tube without repatching the pedalboard. Changing the order alters how the two gain stages interact when stacked, expanding the range of sounds available from the same controls. Players can also switch between true-bypass operation and Keeley's silent buffered switching to accommodate different signal-chain needs, adding practical flexibility for pedalboards built around multiple effects and routing configurations.

Dual Overdrive Built for Flexible Gain Stacking

Built from start to finish at Keeley's Oklahoma City headquarters, the Tube Drive combines traditional tube operation with modern routing flexibility in a rugged dual-channel design. The exposed 12AX7 and custom tube shield put the pedal's high-voltage tube architecture at the center of its visual identity, while independent controls keep both drive voices immediately accessible. For guitarists who want genuine tube response, Keeley's Phat Mod voice and the flexibility to combine and reorder both gain stages, the Keeley Tube Drive Twin Triode Dual Overdrive pedal puts two complementary approaches to overdrive in one enclosure.
