Many say the Phat Mod is their favorite tone from an overdrive pedal. It’s that natural break-up that just feels good and lets you express yourself. The dynamics make it feel alive and part of your fingers. That’s the reason the modified pedal has stayed on people’s boards for nearly 15 years. The Keeley Super Phat Mod is our famous mod now perfected with amazing sounding JFETs that emulate old tube amps in a unique way.

The Keeley BD-2 was the first mod that had a switch.  It was done to give players two modes of bass response, with the slight boost it was called the Phat mode.  Perfect for players of Strats and Teles that wanted just a small push without being muddy.  That same design is also available via the micro toggle on the Super Phat Mod.  Later on we released the Luna Overdrive which won a Gear of the Year award in England and that pedal had further refinements made to it and became the Katana Blue Drive.  The Katana Blues Drive still retained the active bass and treble controls but smoothed out the highs and increased the gain range slightly.  That was an original design designed to meet many of the tonal characteristics of the Blues Driver.  The new Super Phat Mod takes of by duplicating the Keeley Phat Mod part-for-part with the exception of our new “super JFETs”.
