The Keeley Tube Drive Twin Triode is a dual-channel overdrive and tube preamp pedal that blends genuine high-voltage 12AX7 warmth with Keeley’s legendary Phat Mod drive. Running the valve at a real 168 V, it delivers the feel and response of a pushed amp front-end, while the Phat Mod side covers everything from touch-sensitive grit to stacked, saturated overdrive. With switchable effect order, selectable true bypass or silent buffered switching and full control over each channel, it is designed to be the tonal centrepiece of your pedalboard. Unlike many so-called tube pedals that only light the glass, the Tube Drive gives the 12AX7 the voltage it needs to behave like a proper preamp stage. The result is huge headroom, musical compression and a rounded, harmonically rich tone that stays full when you roll your guitar volume back. Dig in and notes bloom and hang in the air; back off and it cleans up without going thin or brittle, making it ideal as an always-on foundation or a responsive gain stage that follows your playing dynamics. The Drive channel is pure Keeley heritage. Based on the iconic Phat Mod that transformed a stock BD-2 into a cult favourite, it moves effortlessly from low-gain crunch to thick, stacked drive. On its own, it is a versatile, amp-like overdrive; stacked into the Tube channel, it becomes a wide, powerful wall of gain that still retains note separation and clarity, even at higher settings. Each channel has its own Level, Drive and Tone controls, so you can dial in two completely different voices and balance them perfectly. Control and flexibility are at the heart of the Tube Drive. A long press on the footswitch lets you flip the signal order, choosing whether the Phat Mod hits the tube for smooth, rounded saturation or the tube pushes the Phat Mod for a more aggressive, cutting edge. The same gesture toggles between true bypass and Keeley’s silent buffered switching, so you can match the pedal to your rig and cable runs. Add in TRS remote switching and a hand-built construction at Keeley’s Oklahoma City headquarters, and you have a professional-grade drive solution that can anchor everything from subtle blues to modern rock tones. High-Voltage 12AX7 Tube Channel The Tube Drive’s 12AX7 runs at a genuine 168 V, giving you real tube headroom, compression and touch response. This means your tone stays clear and musical when you roll back the guitar volume, and blooms with soft, amp-like clipping when you dig in, delivering the feel of a cranked valve preamp under your feet. Legendary Phat Mod Drive Circuit On the Drive side you get Keeley’s renowned Phat Mod voice, capable of everything from warm, touch-sensitive grit to thick, stacked overdrive. Whether used alone as your main drive or stacked into the tube channel, it delivers a rich, harmonically complex overdrive that keeps chords articulate and single notes singing. Flexible Routing and Switching A long press on the footswitch lets you swap the order of the Tube and Drive channels, so you can choose between smooth, rounded tube warmth or a more aggressive, cutting overdrive. The same action toggles between true bypass and Keeley’s silent buffered switching, allowing you to tailor the pedal to short or long cable runs without sacrificing tone. Dual-Channel Control and Remote Switching Independent Level, Drive and Tone controls for each channel make it easy to set up two distinct sounds, from edge-of-breakup to saturated lead. The TRS remote input allows external channel switching, so you can integrate the Tube Drive into more complex rigs and control it from elsewhere on stage.Key Features Dual-Channel Overdrive and Tube Preamp – Combines a high-voltage tube channel with Keeley’s Phat Mod drive, giving you two complementary gain stages in one pedal.
