MGR/Thom Normal's review"Yamaha AG Stomp Box"

Yamaha AG Stomp
399.99 via Musicians Friend, and purchased the pedal separately.

Built like a rock. Easy to read. Limitless possibilities with EQ range and mic simulations. Each simulator effects the sound noticeably, and you can in turn tweek the sounds to your exact specifications with the EQ chorus, and reverb.

Takes time to learn basics. It's complicated.

Like a rock.

Highly recommend for acoustic guitar player who want to customize sound for different songs/types of music. High quality sounds and construction.

Yamaha AG Stomp
Modeling preamp mic, 4-band parametric EQ (adjustable center frequency but not bandwidth) limit, OR chorus delay, reverb "simplified" (hall, room or flat with level control), feedback-killer manual or automatic and tuner.

MIDI in and out, outputs mono / stereo, coaxial digital output (saw for the home studio!), Input for expression pedal and headphone output.

Note a small push / pull off the guitar to mute the output time plugging / unplugging your guitar input: this is a great idea that will prevent many "pops" in the deadly fire of the action!

Regret size: no XLR output so it will provide a (good) DI before attacking the patch.

A major regret: no TAP tempo for the delay .... the 21st century!

A depressing regret not insert effect this quui I think "locked" system completely.

Another great idea on the other hand: you can feed your guitar via a TRS with a small accessory that will house instead of your battery and provided that either the input jack of the guitar that put on / off his Electronic which is the case most of the time.


Handling of the vehicle is not more complicated on its main functions and all available in real time and a "shift" button to access the secondary parameters (such as distance to the microphone emulation for example) .

But if it is to edit on the fly during a concert or if you use many different sounds there it becomes a different story ....
The call mode user incrementally banks quickly drunk if you use a lot of different sounds and MIDI pedal will prevail. For my part I connected a small Rolls from day to prepare my programs. This is reassuring for the scene.

There are some "hidden" functions that are no longer a mystery once you've flipped through the manual that is clear enough (parameters assigned to the external expression pedal, setting the butcher of feedback, pitch of tuner etc ...)

The MIDI implementation is quite complete and it is a good thing.

Tip: keep the manual with you during your first 2 or 3 outputs because it is not necessarily easy to memorize all the key combinations and settings.


We come to the heart of the matter.

Firstly I confirm, contrary to a particular opinions assassin who has been given that the sound is clear and very good signal. It is absurd to compare this material with an amp + a channel strip studio.

You wonder if this thing goes, yes or no, help you finally make your piezo signal something nice to hear but also to play something: yes (phew!).

With my EAN 10 (Takamine) I could get a consistent signal and much warmer than in direct simulation using the first condenser mic. I found the other emulations a little more "hard" in any case less immediate. I think it will depend on your instrument and the time spent well adjust the EQ.
Simulations of tube mics sound good for blues or rock with the medium that goes well (or not!), Dynamic (type 57) are too aggressive for my taste and the capacitors are the most natural.
I made the comparison with Aura Sixteen on which I had spent a lot of time to find the right image for my guitar and good live mix / fx: Ag with Stomp I got a very approaching result in less 10 minutes! And unlike the Aura you can push the mix emulation 100% and get a usable sound.
I'll probably test the use of the Aura in conjunction with Yamaha it could be effective ... I would edit in time.

The EQ is very effective and transparent and extreme settings do not tear your ears. You can really sculpt the sound for each frequency band is adjustable: I advise you to register flat EQ and once found the right EQ in your DAW you just have to copy the Ag Stomp, it is very effective!

The limit works well as strumming to help inflate a solo. I also find it much more relevant using a limit rather than a compressor on the guitar in general .... but there will be noon to each his own door.
By against the threshold is not easy to find and it limits a little too runny for my taste. This is fine for some applications but not close enough if one tries a really clear sound.

The 4-band chorus is quite pretty, can sound thin or thick, and will until the flanger.

The delay is correct, but the tap-tempo should go with I'm already starting to not love too ;)

The reverbs sound great which is good news. They still have this very metal grain Yamaha (mostly flat) but it's still very musical and if you must choose between chorus and delay can, on the other hand, to cook beautiful combinations delay / reverb very large and detailed as they Love :)

Have not yet had to lament feedback problems I can not give you my opinion on the "feedback reduction" and I'm having a highly developed civic sense, I do not see a big cause for feedback our scales or just for what it does :)


This pedal could be the fearsome weapon of guitarist / vocalist but a pure acoustic musician will also find his account for the effects and the signal in general are very good.
In any case this is the solution for traveling light his most plausible competitor is the TC Electronic Nova which is larger and has no emulations microphones.
During the occasion, if you're lucky enough to find one, this is the best deal of time acoustic!

- Quality effects including reverb of the hall.
- Effectiveness of EQ
- Possibility of powering the guitar via jack (if TRS jack and female contact)
- Transparency of the signal
- Connectors for expression pedal (with many assignable parameters)
- MIDI well established

- No real symmetric DI output (grrr)
- No insert effect (not glop)
- No tap tempo!! (Mercy)
- Limit sometimes a bit wild

Yamaha AG Stomp
doc can be downloaded, and all was said.


yes, it is very simple to use, no not enter sub-menus, confused, fast clear effective.
the manual is really easy and detailed.


those who have the breath or a bad model, a lousy power supply, either concensateurs tired, a preamp too low.
I use a crafter, with manufactured by the brand and perfect copy of the LR Baggs preamp, it must have a deal because the sensor is a Lr baggs ...
I listened, well concentrated with the headset, I have no breath, I'll have to test on the amp, which it already, breath a little high volume ...
Finally, I will complete here.
for now, I notice that everything is effective, changes in micro alter the sound of the guitar and I find that these simulations are quite loyal.
Note that this is not to distort the sound, the changes are pretty sweet, but we feel the differences.
patch in memory is good, you can easily create his own.
everything is built for acoustics, not about distorting the sound is fine, and very clean.


I use it for 1 month.
this pedal is very solid, cut to live, no problem.
Special mention for the stereo chorus, beautiful and delay (missing a tap tempo foot is turned to find a button), the reverb is beautiful and without metal tail.
I have yet to test the 5 notch.
limiter is soft and functional (I play with fingers and it does help).
EQ is perfect silence.
This pedal opens me a soundscape, it is finally able to evolve the sound between songs.
Well, I confess: I over-kiffe.
Please note that this pedal does not transform the sound of your hip or in dobro ukulele by-cons, it beautifies your sound without distorting the sound side, it warms the piezo superbly.
Yamaha sucks to have stopped.

Yamaha AG Stomp
Pre-amp for acoustic guitars including a limiter, chorus, time limit, reverb, capable, moreover, of the sound modliser micro static or dynamic tube.


The configuration is fairly simple, but some rglages ncessiteront consulting the manual. The manual is relatively clear. The device is very practical, good ergonomics is trs.


The effects of rverbe and chorus are of good quality. Equalization effective. I bought the unit 1 week ago (I've traveled a lot) to strengthen the signal of a team of folk guitar piezo (without pre-amp).
Regarding the modlisation microphones, capacitor position INTERESTED shuffled with live sound, the other positions I think are truly incidental and unnecessary.


The AG Stomp is a REFERENCE in terms of pre-amp acoustic guitar, the investment is relatively consquent (480 euros) for a device Submitted by the fact few functions. The pre-amp like the legalization trs are effective. I am satisfied with the device compltement, the effects are of good quality trs the device is programmable, which is very practical in concert, and manipulated the foot. The only concerns the BMOL modlisation dynamic and tube microphones (to please the other may be good ... but has not convinced me). Another point I have more paramtres AIM rgler to the limiter, not much more and this unit could have a better quality compressor.
The report qualitpris is good. I purchased the AG Stomp cheaper (MODEL expo) and I am delighted this unit including pre-amp, the legalization, reverb and chorus (which is mainly why I wanted). You can invest is an efficient machine whose performance justifies its reputable.
