Xotic Effects AC Booster
The Xotic Effects AC Booster is a compact pedal for electric guitar that serves as an overdrive and overall signal booster. It has a simple set up with ¼” connections for your input and output and it gains power from a 9 volt power supply. It’s also a true bypass pedal which is something that can’t be taken for granted. It’s not rackable since it’s a stomp box.


The make up of the Xotic Effects AC Booster is fairly simple but still maintains enough controls to give you plenty of options. The basic controls that it has include knobs for gain, volume, treble, and bass. That’s all there is to it so all users should be able to understand this without reading a manual.


The Xotic Effects AC Booster can give you a nice array of sounds and is the perfect boost/overdrive pedal to have at the beginning of your signal chain. It’s ideal for a bit of overdrive as it’s a really transparent sound. It’s also great for even less boost to use just as a simple treble booster for lead parts. It’s not going to give you a thick and chunky sound like a real tube overdrive pedal but it can come close when you turn the gain up a bunch.


You’re going to be hard pressed to find a more complete booster pedal than the Xotic Effects AC Booster. There are a lot of great choices out there to fill this need as a simple Tube Screamer or the Seymour Duncan pick up booster can achieve similar effects, but this one is more versatile than both of those and most boosters out there. It’s not the cheapest out there but it’s worth the extra dough if you’re the kind of player looking for a nice boost/light overdrive pedal to use on a daily basis in the studio or on the stage.

Xotic Effects AC Booster
# Creates a warm and pleasant sound by using the finest quality parts available.
# The super wide range gain control allows for enough gain for it to work as a distorion pedal when turned all the way up.
# Equipped with not only boost Gain but also Treble and Bass controls that allow you to adjust your sound anyway you like.
# True bypass for eliminating any signal interference when switched off.

This is an overdrive offered by Xotic that is said to be like a distortion pedal as it has enough gain on tap when cranked.

Controls: Gain, Volume, Treble, Bass.


Again, most pedals with this type of configuration doesn't require a manual. It's a simple matter of just plugging in, turning the knobs and playing.

The general configuration is simple, not as simple as regular overdrives with JUST the tone knob, level and gain but the AC booster offers treble and bass knobs to further tweak the signal.


This is a great sounding pedal. I've used it as both a mild overdrive and a distortion pedal. I've also recently learned that paul gilbert has one of these on his boards and kicks it in when he does some super shreddy passages with the gain all cranked out.

The sound itself is rather transparent, it doesn't add yet it does have a character of it's own. That character is that it's clear and slightly scooped to my ears. All notes are cleanly heard within a chord and leads pop out. Everything just seems to be clearer and more defined.

As an overdrive it is also quite good, transparent, thick but clear. The sound is very organic and open sounding, definitely not compressed.


I think all the xotic pedals, the BB AC and RC have a similar character to them. Where the signal is generally open sounding, thick and clear but not heavy. The differences would mainly be, as I've experienced, gain amount. The BB being the one with the most amount of gain on tap as far as I'm concerned, and this the AC being the next while the RC is meant for more of a clean boost.

I like all of these as they all have the same type of character, yet the AC seems to retain it's clarity when the gain is maxed compared to the BB and other pedals. Which I guess, was the design and purpose of the pedal. Noise is always a factor with pedals when the gain knobs are maxed. This is probably why Paul just does it when he's doing the shreddy stuff and turns it off immediately after.

Overall, great overdrive pedal from Xotic. Modern sounding, uncompressed, open, slightly scooped yet transparent and thick, but not heavy.

Xotic Effects AC Booster

(Although QUAC either AC30 priori?).
I think that's Almost Clean

RC for real clean

... I have the BB + and it is really beautiful in the progression of crunch

Xotic Effects AC Booster
This is a booster / overdrive, it's not complicated.
Well, it's yellow and did some work on a pedalboard, but as it sounds ...


4 knobs ... there is no simpler than OD.


I'll make it short because everything has already been said, this pedal is outstanding.
I use a clean boost for its slightly crunchy.
It landed directly on his rock to fall: very dynamic, with a big fat grain airy, and very faithful to the guitar and the amp. It not ring at all "pedal" is like the basic sound with more gain and grain.
I also used to boost another OD for lead levels: it is also a perfect job, it tightens the grain and increases the gain, with a small bump in the mids welcome. That's perfect.


I finally managed to get my Bad Monkey in the closet, everything is more qualitative information on the AC.
I tested a lot of TS-Like, the Red Dirt and Keeley TS808-HW, supposedly improved TS808, but ultimately too "stiff" and relatively tasteless.

The ratio q / p is very good opportunity.
I would do this choice ... a revelation!
