With the Xotic EP-Pro, you don’t just get an EP Booster in a volume pedal enclosure—you gain access to an unlimited tonal palette through unique controls that sculpt and shape your sound exactly the way you hear it. The adjustability and flexibility of the Xotic EP-Pro make it one of the most versatile pedals on the market today. The EP-Pro builds on the iconic EP Booster, which captured the legendary Echoplex preamp sound made famous by players like Jimmy Page and Eddie Van Halen.

Now refined for modern musicians, the EP-Pro is a multifunction preamp and volume pedal that delivers refined tone shaping, flexible volume control, and that unmistakable analog warmth. That “always-on” sound you never wanted to play without now comes with dedicated volume and EQ control—classic tone with modern versatility.

Designed to strengthen the connection between instrument and player, the EP-PRO enhances not only your guitar’s sonic signature, but also the nuance, articulation, and responsiveness between your hands and your amplifier. It allows your touch to shape the sound naturally—not by hiding it behind processing, but by amplifying the most subtle expressions of your playing.

Thanks to the FET boost built into the pedal, you can enhance your guitar tone in a very natural and musical way—adding just the right amount of nuance and allowing the amp to respond more freely to your playing. In the end, it’s not just about volume, but about controlling feel and responsiveness so you can play more comfortably and achieve a better overall sound. This is a core principle of our tone philosophy: improve nuance and response, and you improve tone.

Another approach is to place the EP-PRO in your amp’s effects loop. In this position, it functions not only as a volume pedal, but also as a boost that lets you shape your tone directly at the power-amp stage. It’s a great way to add extra sparkle and nuance to your overall sound. You’re not just controlling volume—you’re enhancing the character of your amp’s output stage and giving it added shine.

You can also place the EP-PRO at the very end of your effects chain—just as many players did with the original EP Booster. Positioned after drive and modulation effects but before delays, it allows you to shape your final tone and control overall thickness and volume. In other words, it’s an ideal way to refine the entire signal at the end of your chain. The EP-PRO can serve as both a volume pedal and a final tone shaper, giving you easy control over how dense and cohesive your drive and modulation effects feel in the mix. Plus, you gain smooth control over your overall volume.

Finally, if you’re using digital platforms such as Neural, Line 6, or Fractal, digital amp simulations can sometimes lose some of the subtle analog sensitivity we love. For that reason, I recommend placing the EP-PRO in front of your digital chain. This allows you to fine-tune your input gain and shape your tone with the EP-PRO’s boost before the signal reaches the digital device. You maintain a more organic response and gain far greater control over your final sound. It’s a seamless way to dial in exactly the feel you’re looking for.
