One-knob booster.

First of all, there's two dip switches inside the box, both "on" when you receive it :

The first gives you a 3db extra boost (among the 20db available) when it's on, and a "unity gain" when it's off
The second gives you a flat EQ when it's on, and a "vintage setting" (less treble) when it's off.

The truth is, in my case I just can't use it as a boost. There is no unity gain, the volume increase is way too huge, even with the knob at a minimum. That explains the 4, because I bought it for that exact purpose, get a slight boost for solos, and I absolutely can't use it that way.

I came to find out that it works well as a boost BEFORE the distortion/overdrive. In that case, the volume increase is less obvious, and gives more density and gain to your sound. Unfortunately I use only the clean channel on my 1-channel amp, so I can't use it that way either. Note that on a clean channel, the volume increases much more, can't tell you why.

So, in the end, I placed it after all my effects, just before the amp. I use it as an always-on effect. Its only purpose : get unity output between different guitars. You simply turn the knob up for a guitar with less output.


I just said it above, always on in my chain effect. It's one knob anyway so it couldn't be easier.

Speaking of the manual, it is simple and clear.


Oh my god. Once you put the Ep Booster on, you never want to put it off.

When you put it after all your effects, the Ep Booster has an overall effect on your sound that is incredible. It's lush and shimmering, very natural and non-invasive, it's still your tone.

That's Xotic quality.



Xotic made a huge mistake, in my humble opinion, calling this a boost. It's a great effect, but with the wrong name. They should have called it "enhancer - master volume" or something like that.

If you want a slight kick of whatever to cut through the mix, don't buy this. You'd not be happy with it.

But if you have several guitars and don't want to mess with your amp settings, this is the best thing you can get. Put it on forever and adjust the knob according to your guitars outputs. Plus it will enhance your overall sound, in the simpliest and best way possible.
