Keeley Limited Edition Tube Drive 12AT7WC Dual Overdrive Pedal

The Keeley Tube Drive 12AT7WC is a strictly limited dual overdrive pedal built around a single, very special valve. At its heart is a genuine 1987 Philips JAN 12AT7WC, a military grade tube running at a proper 168 V for authentic high voltage feel, touch and headroom. Paired with Keeley’s legendary Phat Mod drive circuit and flexible routing options, it delivers everything from warm, transparent tube grit to huge, stacked overdrive tones. Limited to just 300 units worldwide, this is a centrepiece drive pedal for players who want real valve character underfoot.

Unlike typical ‘starved plate’ tube pedals, the Tube Drive 12AT7WC behaves like a pushed amp front end. Roll your guitar volume back and the Tube channel stays clear and musical instead of going thin. Dig in and you get that soft, elastic compression that makes single notes bloom and hang in the air. Add in the Phat Mod channel for extra gain and thickness, and you have a versatile, gig ready drive solution that can cover low gain edge of breakup, classic rock crunch and saturated lead sounds with ease.

Each channel has its own Level, Drive and Tone controls, so you can set up two distinct voices and switch between them on the fly or stack them together. 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 voice. You can also choose between true bypass and Keeley’s silent buffered switching, making it easy to integrate the Tube Drive into any pedalboard, from compact grab and go rigs to complex touring setups.

Hand made in Keeley’s Oklahoma City headquarters and powered from a standard 9 V DC supply, the Tube Drive 12AT7WC is designed to be the tonal foundation your whole board is built around. Whether you use it as a responsive always on tone shaper, a flexible dual channel overdrive, or a stacked gain monster, that vintage 12AT7WC valve keeps everything sounding rich, dynamic and unmistakably amp like.

High Voltage Tube Warmth

The Tube channel runs a genuine Philips JAN 12AT7WC at around 168 V, so the valve operates in its proper range rather than at a token low voltage. The result is real tube feel under the fingers, with huge headroom, smooth compression when you dig in and a clear, musical response when you roll your guitar volume back.

Legendary Phat Mod Drive

The Drive channel is Keeley’s renowned Phat Mod circuit, originally famous for transforming a stock BD 2 into a touch sensitive, amp like overdrive. On its own it covers everything from subtle grit to thick, singing lead tones, and when combined with the Tube channel it becomes a fat, articulate wall of gain that still keeps excellent note separation.

Switchable Effect Order and Bypass Modes

A long press on the footswitch lets you flip the order of the two channels, so you can run Drive into Tube for smooth, rounded saturation or Tube into Drive for a more aggressive, cutting character. The same gesture also toggles between true bypass and Keeley’s silent buffered switching, giving you the choice between pure bypass or improved signal integrity on longer cable runs.

Dual Channel Control and Remote Switching

Each channel has its own Level, Drive and Tone controls, making it easy to dial in two distinct sounds and balance them perfectly. A TRS remote input allows external channel switching, so you can control the Tube Drive from a remote footswitch or switching system and keep your pedalboard layout as flexible as you need.
