Keeley Electronics Tube Drive Limited Edition 1987 JAN 12AT7WA

Maker: Keeley

Model: Tube Drive

Condition: Brand New

Description: 

The Keeley Tube Drive Twin Triode Dual Overdrive 12AT7WC is built for players who want real tube feel, rich overdrive, and collectible Keeley craftsmanship. This limited edition Tube Drive pairs a genuine high-voltage tube preamp with the legendary Keeley Super Phat Mod drive circuit, giving you two distinct gain voices that can be used alone or stacked together.

The tube overdrive section runs both triodes in series in Class A. The pair of amplifiers then feeds into a vintage tweed-amp-style tone stack. At the heart of this LTD Edition Tube Drive is a vintage 1987 Philips JAN 12AT7WC tube. Each tube is carefully selected, burned-in, tested, and proudly displayed behind a custom Keeley tube shroud. Expect warm grit, touch-sensitive breakup, and the kind of dynamic response that makes a real tube circuit feel alive under your fingers. Swap the tube any time you’d like with the tube extraction pin and included allen key.

The second side of the pedal is based on the Keeley Super Phat Mod, one of our most loved overdrive circuits. It adds punch, sustain, and thick amp-like drive while keeping the clarity and character of your guitar intact. Use it as a standalone drive, push the tube side harder, or stack both sides for huge lead tones and saturated rhythm sounds.

The Tube Drive is built for real-world pedalboards, with all connections placed conveniently along the jack side of the enclosure. The pedal features standard Input and Output jacks, plus a dedicated Remote jack for expanded switching control. Power comes from a standard 9VDC center-negative supply with a minimum current rating of 500mA. Inside the pedal, the tube circuit is amped to high voltage for authentic tube performance, while the external power requirement stays pedalboard-friendly. A vented jack plate helps manage airflow around the tube section, while the rear-panel warning mark clearly identifies the high-voltage design inside. It is a clean, professional layout that keeps the Tube Drive easy to wire, easy to control, and ready for any rig.

The Tube Drive 12AT7WC also includes selectable true-bypass or Keeley silent buffered switching, making it easy to integrate into modern pedalboards and professional rigs. A simple foot gesture switches the effect order on the fly, so you can place the tube preamp before the Phat Mod or run the Phat Mod into the tube side. This gives the Tube Drive 12AT7WC a wide range of tones, from warm low-gain texture to thick, harmonically rich overdrive with serious push.

Each pedal is individually numbered on the face of the enclosure as part of the limited run of 300 units. Designed, assembled, tested, and finished at Keeley Electronics in Oklahoma City, the Keeley Tube Drive Twin Triode Dual Overdrive 12 AT7WC can only be found within Keeley’s authorized dealer network while they last.
