Tube Drive

The Keeley Tube Drive Twin Triode Dual Overdrive 12AT7WA is a limited RKFX.com edition combining two independent gain circuits: a genuine high-voltage tube preamp and the Keeley Super Phat Mod overdrive. The tube section uses a tested vintage 1950s Sylvania 12AT7WA, with both triodes running in series in Class A and feeding a vintage tweed-amp-style tone stack. The two effects can operate separately or be stacked in either order, switchable by foot gesture. A Remote TRS jack provides external control of Drive and Tube. It offers selectable true bypass or Keeley silent buffered switching and requires 9V DC center-negative, minimum 500 mA. This brushed-gold version is individually numbered as part of an initial run of 100 units and allows tube replacement.
