The Digitech EX-7 Expression Factory features emulations of 7 popular and vintage effects - Cry Baby wah-wah, Vox Clyde McCoy wah-wah, Digitech XP300 Space Station, Digitech Whammy, Unicord Univibe, Leslie Rotating Speaker (my favorite of the group), ADA Flanger. Each of these effects has 3 parameters that can be controlled by the knobs.
In addition, there are 7 different distortion/overdrive emulations that can be added to each effect. These are Ibanez TS-9, DOD 250, Boss DS-1, Pro Co Rat, Boss Metal Zone, Digitech Metal Master, EHX Big Muff. There are also controls for these effects. The modulation effects are engaged by the toe switch. The distortion effects are engaged by a heel switch. The pedal can also be used as a volume pedal. Plugging in a Digitech FS3X footpedal allows you to switch between the effects remotely. There are several different output modes available. The owner's manual can be easily found online for further feature descriptions.
The pedal is in good shape. There are a few scratches and paint chips, but it is sound mechanically. The power supply is included.
