Keeley Tube Drive – Twin Triode Overdrive Pedal

Product Description

The Keeley Tube Drive Twin Triode Dual Overdrive combines two distinct drive circuits in one pedal: a genuine high-voltage 12AX7 tube overdrive and Keeley’s renowned Super Phat Mod.

The tube side runs a Russian 12AX7 at 168V, with both triodes operating in series in Class A before feeding a vintage tweed-style tone stack. The result is warm grit, touch-sensitive breakup and the dynamic response of a genuine tube circuit. Each tube is selected, burned-in and tested by Keeley before being protected behind a custom matte black tube shroud.

The second drive is based on the Keeley Super Phat Mod, delivering punch, sustain and thick amp-like overdrive while retaining clarity. Each side can be used independently or stacked, with a simple foot gesture allowing you to reverse the effect order on the fly. Run the tube circuit into the Phat Mod or reverse the order for different gain textures and responses.

True bypass and Keeley silent buffered switching are selectable, while a dedicated Remote jack provides external control of each drive section. Designed, assembled, tested and finished at Keeley Electronics in Oklahoma City, the Tube Drive combines genuine high-voltage tube performance with flexible dual-overdrive functionality.
