The Xotic EP-Pro is a large-format pedal that combines a boost with a volume pedal mechanism in one housing. Its boost is switched by a heavy-duty momentary switch, and the volume pedal uses a nylon pivot design that Xotic says ensures smooth pedal operation and adjustable torque, inherited from the company's XV pedals. The pedal carries a lightweight yet rugged aluminum chassis, measures 8.27" (210mm) deep by 3.94" (100mm) wide by 2.64" (67mm) high, and weighs 2.16lb. (980g).1
The EP Booster circuit the EP-Pro builds on captured what Xotic calls the legendary Echoplex preamp sound, and the company positions the EP-Pro as the always-on tone enhancer with classic sound and modern versatility, offering analog warmth.1
What it does for a player
The EP-Pro covers two jobs at once. As a volume pedal, Guitar Pedal X's Stefan Karlsson wrote that it "covers full-size Volume pedal duties while adding more control," and his verdict was that "if you're considering a full-size Volume pedal - then this covers that and delivers a lot more."2 As a boost, the FET circuit can be switched on or off with a heavy-duty momentary switch, so it can sit always-on as a preamp or come in as a lift.1

EP-Pro and EP Booster
The EP-Pro is a larger, more featured take on the EP Booster rather than a successor to it. Karlsson put it plainly: "The EP-Pro isn't really a replacement for the EP Booster - its footprint is much more extensive."2 Players who want the Echoplex-style preamp in a small enclosure still have the compact pedal; the EP-Pro adds the volume control and the bigger housing to the same family of sound.12
Power and connections
Power is straightforward, with one thing to note about the adapter range:
- Battery: one 9VDC (006P) battery, approximately 40 hours of continuous use with an alkaline battery1
- Current draw: 10mA maximum at 9VDC1
- AC adapter (optional): 9VDC to 18VDC, negative tips, regulated only1
- Nominal input and output levels: -20 dBV1
Xotic specifies the adapter supply as regulated only, from 9VDC to 18VDC with negative tips.1
Specifications
| Specification | Value |
|---|---|
| Input impedance | 500k ohm1 |
| Output impedance | 2k ohm1 |
| Nominal input level | -20 dBV1 |
| Nominal output level | -20 dBV1 |
| Dimensions (W/D/H) | 3.94" x 8.27" x 2.64" (100mm x 210mm x 67mm)1 |
| Weight | 2.16 lb. (980g)1 |
The chassis is a lightweight yet rugged aluminum enclosure, which Xotic describes as durability without the bulk.1 The pedal is listed in the Xotic online shop for end users under model number EP-PRO.3

Questions
Does the Xotic EP-Pro take a battery?
Yes. Xotic lists a single 9VDC (006P) battery, with approximately 40 hours of continuous use from an alkaline battery. The pedal also accepts an optional regulated AC adapter from 9VDC to 18VDC with negative tips, so you can run it either way.
Is the EP-Pro true bypass or buffered?
Both, depending on how you set it. Xotic specifies True Bypass or Buffered Signal Switching for the boost on/off function, and the choice is made with DIP switches inside the pedal. That lets you match the switching to the rest of your board.
How much current does the EP-Pro draw?
Xotic rates power consumption at 9VDC and 10mA maximum. That is a light load by pedal standards, and it is the same supply that gives roughly 40 hours of continuous use with an alkaline 9V battery.
What is the difference between the EP-Pro and the EP Booster?
The EP-Pro builds on the EP Booster, housing an enhanced EP Booster circuit together with a Volume Controller in a much larger format with a more extensive feature set. Guitar Pedal X's Stefan Karlsson noted it is not a replacement for the compact EP Booster, since its footprint is much more extensive.
What are the EP-Pro's input and output impedances?
Xotic specifies an input impedance of 500k ohm and an output impedance of 2k ohm. The 500k input is high enough that the pedal should sit well with passive pickups, and the 2k output is in the usual range for driving downstream pedals and an amp input.
