Many say the Phat Mod is their favorite tone from a 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.
Here's a clip of the Super Phat Mod on a low gain setting, providing subtle, glassy breakup at lower volumes.
