Blues Driver Phat Mod
Inside, there is a Blues Driver circuit that clips asymmetrically based on regular diodes and LEDs. Which is based on a 20 year old modification first performed with the Keeley Blues Driver Phat Mod.
Apparently, the topology of the pedal is similar to classic California tube amps, according to Keeley, and they substitute JFET transistors in place of tubes.
This all helps to give the pedal an amp-like feel.

AT Mod + Phat Mode
The special feature of the red pedal are the two variants or Modes that are set with the small toggle switch. Either you use the AT mode, AT stands for Andy Timmons, and the sound is a little tighter and more transparent in the voicing.
In addition, there is the Phat mode, with which you can give your single coils a little more depth and body.
Plus, it has the standard level, tone and drive controls that control the basic overdrive parameters. Apart from the two modes, it is a pretty simple pedal to dial in and use.
The video demoes below give a good indication of wha to expect from this overdrive circuit.
