Real Tube Warmth Meets Modern Modded Drive Symmetry
The Keeley Tube Drive Twin Triode Dual Overdrive packs two distinct, high-performance voices into a single road-ready enclosure. On one side sits a genuine high-voltage (~168V) vacuum tube preamp running a hand-selected, fully burned-in 12AX7 tube. On the other side is Robert Keeley’s legendary Phat Mod drive circuit—delivering touch-sensitive grit, fat low-end response, and dynamic gain structure.
Designed and built entirely at Keeley’s Oklahoma City headquarters, this pedal gives you complete control over your signal chain. With a simple foot gesture, switch effect order on the fly (Drive → Tube or Tube → Drive) or toggle between silent buffered switching and true bypass to match your pedalboard's impedance needs.

- Sanctuary Expert Note: "Running a real 12AX7 at 168V with 100V to the plate makes all the difference here. It doesn't mimic tube feel—it IS tube response, making it the ultimate amp-in-a-box frontend for clean or edge-of-breakup rigs."
