Xotic Effects has released the EP-Pro Preamp Boost & Volume, a large-format pedal that combines an enhanced version of its EP Booster with a volume controller, Guitar Pedal X reported on February 9, 20261. The pedal is listed at $295 on the Xotic Effects webstore1.
The EP-Pro houses the boost circuit and a volume treadle in a 210mm enclosure of the type the maker uses for its wah pedals, compared with the 89mm EP Booster1. Xotic describes it as "a multi-functional preamp and volume pedal that offers refined tone shaping, flexible volume control, and that unmistakable analog warmth"2. The maker says the EP Pro builds on the EP Booster, which it says captured the Echoplex preamp sound associated with players including Jimmy Page and Eddie Van Halen2.
Controls are boost on/off, volume treadle, master volume, gain, treble and bass1. The boost footswitch is a momentary type; depending on whether the internal buffer is on or off, it toggles between boost and true bypass or between boost and a buffered bypass signal, set with internal dip switches2. Xotic says the treadle mechanism is inherited from its XV pedals, with a nylon pivot and adjustable torque2.

Guitar Pedal X described the EP-Pro as not a replacement for the EP Booster because of its larger footprint, and its author wrote that he is not a fan of large-format wah-pedal enclosures, while calling it "a good proposition" for certain players1.
