iamqman's review"Nice pedal!"

Boss AC-3 Acoustic Simulator
This is Boss's newest edition to the acoustic simulator. This is virtually the same exact pedal as the Boss Ac-2 but this has one added feature of reverb. Within the level control knob you have a sub control knob that allows how much reverb you want in the signal. This is a nice addition to an acoustic sound.

When I first heard about the acoustic simulation pedals I was a little bit leery of how good the simulation would sound. Then I heard Slash from Velvet Revolver and Guns N Roses use one live in some gig I saw on tv. To my pleasant surprise it actually sounded pretty good. He was playing a Gibson Les Paul and those guitars can be very girthy and robust on tone and to get a guitar like that to sound like a wood hollow body it a big feat of strength.

BOSS AC-3 Acoustic Simulator Features:

BOSS's most advanced acoustic-guitar modeling in a compact pedal
Four simulation modes: Standard, Jumbo, Enhanced, and Piezo-equipped
Top and Body knobs for fine-tuning the virtual-body resonance
Built-in reverb, optimized for acoustic-guitar simulation
Advanced modeling for authentic acoustic guitar sounds
Fine-tune controls to shape the acoustic sound you want
Reverb included
Versatile output paths


The only difference in this and the AC-2 is reverb. all the same tone and simulation is the same. the tone of this pedal is decent for the playing who doesn't want to carry an acoustic guitar to a gig and only use it for minimal parts. You can just bring this pedal and your favorite electric guitar and have that acoustic sound quickly and easily for live uses.

This pedal does work and works very well. Let me be very clear, it will not replace the tone of a real acoustic guitar no matter how trashy a cheap acoustic guitar sounds. If you have a cheap acoustic guitar, that guitar will sound better and more natural than an electric guitar using this pedal. However, this is great for a gigging musician that has an acoustic part in a sound and needs to switch quickly to an electric part of a song.


At new these pedals come in at around $129, which isn't bad for a pedal like this. You get a great sounding simulation for acoustic and a nice added reverb section.

I would not recommend this pedal as a replacement for an acoustic guitar in a recording session. This pedal will not get the hollow tone or organic feeling of a real acoustic guitar.

Boss AC-3 Acoustic Simulator
The Boss AC-3 Acoustic Simulator is an analog guitar pedal designed to make your electric guitar sound like an acoustic guitar. It has a 1/4 inch input as well as two 1/4 inch outputs - one to send to your amp and one is a line out. It is powered by either a nine volt battery or a nine volt power supply. It is not rackable as it is a stomp box.


The configuration of the pedal is pretty basic. You've got a knob to choose between different modes that includes standard, jumbo, piezo, and enhance. The other knobs control body, top, level, and reverb. It is easy to get a few different sounds from this, and is really an EQ that is specific for making your guitar sound more like an acoustic. I don't have the manual but this pedal is easy enough to use that I never had a need for one.


The sound quality of the AC-3 is about average. It is pretty hard to simulate an acoustic guitar with an electric, and this does an okay job of doing it. It won't blow you away, but does have a good amount of control to zero in on sounds that you might be looking to get. I have only used this with electric guitar, as that is what it is made for.


I've been using the Boss AC-3 Acoustic Simulator for about two years. I wanted it so that I wouldn't have the switch between acoustic and electric guitars during a live performance. However, I have found that it is worth it switch as you can't really replicate an acoustic with an electric. This being said, this pedal does a decent job of emulating it. If you really want an acoustic sound, just use an acoustic guitar!

guigue106's review (This content has been automatically translated from French)" very well if c is split"

Boss AC-3 Acoustic Simulator
already mentioned!


manual = not useful
edition = you turn the knob you find .... or not
config = RAS


4 effects on offer we good acoustic sounds that are really, little more with respect to the ac 2 c is the reverb and cosmetics.

Amplifies the reverb quality "studio" and toner allows some specific acoustic environment seem less dry, I appreciate this little longer (ca avoids add a RV5 was the 140th for example)

my choice esp m2 active (EMG SA neck) ca go very clean, very crystalline and a lot of flexibility in the sounds obtained at the border or velvety :) j alternates with my JEM (penultimate position in the sector in bridge) and there is a clean and close to real acoustic kick, or more precisely the electo acoustic.

j 'well appreciate the jumbo and piezo I'm pretty close to what I hoped with 2 settings (minus the enhancer and the standard) is acting on the body and BODY actually more or less wide one feels in amp and top sets the color of the thickness (in fact c is balanced bass / treble) once this balance easily find it works alone.

although the reverb will also give a significant dimension to your "electro".


it works pretty well.

Warning realize very ugly in ca ca humbuker still too "electric", it must split, c is advisable to get something nice.

need to put everything thoroughly ca is nothing, the body is half way (noon) and top ("color") has 3h, ca already a big thank acoutique quality (jumbo or piezo position, the other is c enhancer / j standard have not yet been convinced)

on the other hand superb quality reverb integrated studio quality assured if plugged into the PC line out with guitar rig, I've asked a 2nd reverb (stuidio verb) in addition to the ac3, and ultimately we believe in a real recording studio a good definition, good texture and reality that exceeds the simulation.

no aggression, no saturation of the signal good investment (certe a bit expensive) good 65 euros but at least I have an "electro acoustic" at home in less clutter and not the budget to invest in the installation of a Piezo on one of my guitars.

j I test the ac Beringher, I puked direct: x, I have a little look elsewhere (especially in mfx, but a little disappointed when even), but the size of a pedal boss, I'm rather happy , it works on all my guitars (splittée) and of course as I hoped to rig, nikel chrome: D

8 because of the enhancer and standard.

yes I think if I had to make the choice that will be carefree

Nico66's review (This content has been automatically translated from French)" a toy ..."

Boss AC-3 Acoustic Simulator
Boss Digital.

Beefy ... but that's it ... on paper, very attractive, but when you go to use it is another thing.


simple manual ... editing sounds easy


sound quality ... it blows a lot!
the only use is with a guitar single coil middle pickup set in, that's all! for the rest, forget it.

And yet, it's not great great ... and it blows a lot. Too bad the idea was pretty good.

basically it is a toy for home, but in concert, forget ... this is ridiculous ...

for those who would say yes, but you got to plug it into the good stuff, I play on Orange Orange Rockerverb MKII + 4x12, Fender Twin reverb and guitar custom shop Start, PRS 513 and the CS 56 and 58 Paul ... ok?


I bought it because I was fed up of lugging 4 guitars in concert and I thought if I could leave my folk at home that would be it ...

ben good too bad, I take the folk ... it really is not terrible ... for those who hallucinate before, get your ears ... it sounds good, but get a electro and compare ... ok? it's good?

go to waste!

MikePetrucci's review (This content has been automatically translated from French)" Very good"

Boss AC-3 Acoustic Simulator
Numerical simulation of acoustic sound.

Connectors classic plus a Line Out if you want to get out the acoustic sound directly through the console.


Very simple, but plan a little time to find a sound that suits you because the 4 pots (5 in all, the penny is the level of output) have a definite influence on the sound.

It might take a while to find the right combination:
1) Reverb
2) Body (which simulates a large body more or less)
3) Top (gives brilliance, treble)
4) selection of the type (piezo, jumbo, dreadnought or Enhance)


Very good sound quality, a caveat: it blows a little in spite of a diet with the Fuel Tank Chameleon. A noise gate can be nice.

I have not tried yet coupled with a compressor, and I also think it can do as well: my mutli converters downstream effect tends to saturate when the pedal is ON.

(Use humbuckers should be avoided, the report is not top)


A very good pedal that does its job. Do not expect to have a real acoustic sound, but they're very close, even in the MesaBoogie.

The negative points are the slight wind that happens when you increase the TOP and the fact that the sound that comes out has a gain range of really important, which tends to saturate the multi-purpose converters.

Really trying!

Kak's's review (This content has been automatically translated from French)" S this pedal effect"

Boss AC-3 Acoustic Simulator
This is of no surprise BOSS quality


Ms. notices


Essay on several guitars electric diffrentes (Gretsch (humbuckers) Tlcaster (single coil) Rickenbacker (single coil)) with tube amp Marshall Vintage lamps or directly on my sound system. This pedal has virtually no effect. There is no change "bluffing" as I told the seller. I trsdu with this pedal.

I remember there was a very long time (25 years +) in a village prom seeing a guitarist with his guitar playing a piece of electrical Gipsy Kings with a guitar sound sche. The really stunning c'tait! It is this device that I would like to have ...


I use it for 3 days. I'll take it to the store - damage.
If anyone knows a truly reliable acoustic simulator, I'm interested.

Boss AC-3 Acoustic Simulator
- What are the effects or types of effects available?
Simulation of acoustic guitars Jumbo, Standard, Enhanced, and Piezo.

- What technology is used? (Analog, digital, tube ...)

- Are they ditables? Via a publisher Mac / PC?

- What is the connection? (Audio / MIDI)
Between 1 and 2 jack output

- Is this a rack or rack model?
Yes, it is a format 32 U rack


- Is Gnrale setup simple?

- The edition of sounds and effects is it easy?

- Is the manual is clear and sufficient? ...?


- Are the effects effective and sufficiently ADAPTS GPs?
There continues to be reverb. I do not use it because I use rather reverb G-System

- Which instruments do you use?
Branch in loop 1 of my G-System
I use it with my prfrence humbucker neck to give more thickness to the sound.

- What are those you prfrez, you dtestez?
I juggle with two rglages, namely the "standard" mode and "enhanced"
For the moment I have not packed by t rglage "Jumbo".
Depending on the used mode and rglage the knob "Body", I must often adjust the knob "Level" under penalty of having a lightweight saturation. Indeed the parameter Body gives more chest sound when pushed to the maximum.
This is not a problem in itself, and even normal.


- How long have you use it?
2 weeks

- What is the particular feature you like best and least?
It must be clear, this pedal will never give you sound of acoustic guitar.
As against it renders very well the tone of a guitar transplanted into a sound system. If you know what I mean ....
It colors very well my clear sound and allows me to have anything other than a clear sound.

- Have you tried many other models before acqurir?
not. I bought the pedals, eyes closed and mouths ears ...
"Eh what!?! It sounds how this pedal?" I cry several times lol seller

- How do you report qualitprix?
Very good!

- With the exprience, you do again this choice ...?
Yes, I think trssrieusement buy a SECOND in the future to plug it into another loop of my G-System to no longer juggle rglages to switch modes the other (yes I know, I'm lazy)

Boss AC-3 Acoustic Simulator
Acoustic Simulator
- A volume knob
- Rverb of a (very beautiful)
- 2 of rglages body and top
- A 4 position depending on the type of Grat desired (standard, jumbo, ...)


It's simple, there is what you want quickly
I see too much What are the top two pots and body, but I recently
changes to its standards are no longer with the 4 positions
Personal I use the jumbo that makes the most 'noise'


Then I read the all, especially Harmony Bay, and critics taient not terrible
so I tried before
and I can tell you with a tl and a marshall mode clean, it's pretty patant!
I rpt uses and other members of the group t breath
Now, with another configuration (humbuckers) I do not know if the fact has
So try before you buy
rverb the trs is really pretty


I bought it secondhand in Roros 65 and I think it's a purchase winner
but also try on with your configuration, otherwise be of
