Keeley Electronics Tube Drive runs a 12AX7 valve at 168V from standard 9V power. This dual-channel pedal costs £389 and ships with genuine tube warmth plus compression that responds to playing dynamics.
Rolling back guitar volume keeps tones clear without thinning out. Hitting the input harder triggers natural sustain and compression. The Phat Mod circuit handles aggressive stacked overdrive territory while lower gain settings stay reserved.
Channel order reverses with a long footswitch press. Users stack Tube into Drive or flip that signal path instantly. Independent Level, Drive, and Tone controls exist per channel for precise shaping.
Selectable true bypass or silent buffered switching accommodates different rigs. A TRS remote input accepts external footswitches for hands-free operation. Each 12AX7 tube gets burned in and tested before installation behind a custom shield.
Oklahoma City craftspeople build these units by hand. Current draw sits at 485mA using center-negative 2.1mm DC supplies. Real valve behavior emerges because the high-voltage design lets the tube operate as intended.
