Mooer F40i Li Model. Guitar Combo PB

I got it for home practice and quiet band rehearsal, not expecting much since online it got some hate for having bad sound quality and meh presets. While that might have been true when the amp was first launched, I saw that Mooer made a software update for it and from what I've seen botn with my model and online they really fixed everything that was to fix.
The sound quality was its main issue from what I read online, but in recent reviews and also when I play on it irl it sounds amazing, somewhere around positive grid spark level or even better, not to mention it has IR loading which makes it sound amazing compared to anything else I tested at local shops(which were amps under my 400 euro budget, but still). It also keeps sound quality really well at both very low and very high volumes and from what I tested with mine it can reach ~105db with no issue and possibly even higher if you tweak it from the app.
The other thing it got bad rep for was the presets it came with, which to be honest is not that big of a deal considering how much tweaking it allows you to do to get amazing tone, but honestly even those presets that come with it are pretty pleasant to play on and I don't really see why this amp whould get any more hate on that.
Now for things that aren't really spoken about online but i think should be mentioned:
The amount of customizability you get for your tone is insane. It has way more effects than spark and from a larger variety. It also lets you configure the order the effect chain which seems like another way to make sure you get your tone right. The naming of the effects in the app was a bit difficult to understand for me, but once you get used to it its no biggie, and for the 80 presets slots you can save and edit it lets you experiment enough to figure them out fast.
Some effects i really like on it are the octaver that lets you add a lower or higher octave to your tone and you can make it sound like you have a pad doubling your guitar. You also get some fun effects like a "glitchy" distorsion for retro video game sfx.
The only issue i have with the effects is that i thought the octaver would let me transpose the notes i play on guitar so it would sound like a bass, and it sort of does that but it also has some latency which is hard to get used with and even after you get used to it, it gets annoying to play with.

Now to the Mooer AI function, which is one of the things that really gets it competitive with spark:
It doesn't assist you that much with tweaking since unlike spark, it doesn't tell you what effects it can add to you tone and how each impacts it, but it still gives you three options to try for each propmt you give it so you usually find the tone you like. When asking for an exact tone to make from scratch the Mooer AI is, in my opinion, slightly better than spark since it gets much closer to the tone of certain songs when you ask for it, but this is still somthing of personal preference so my opinion might not be the same as other buyers.
Another fact i find really nice about it is the battery. It is listed at a runtime of 4-5h, but using it it seems to last more than that. While playing guitar on it at moderate volume(so about 30% since I live in a flat and more than that is loud enough to get to neighbours) it got to about 6h and if i use it as a bluetooth speaker(since it has that option too) i barely drained 10% of its bettery for a over 2h long movie(Matrix), so maybe the 4-5h listed runtime is estimated for more intense usage- higher volume and not just bluetooth playback which drains the battery much slower than playing on guitar.

In conclusion I'm very sattisfied with my purchase and reccomend this amp to anyone who wants a lot of features for an accessible price. Really, for sub 400 euro, i dont think there's anything that beats it as a whole.

Der F40i Li ist ein sehr guter Desktop Amp. Der Sound überzeugt und reicht - im Gegensatz zum kleinen Bruder F15i Li - auch in einer lauteten Umgebung vollkommen aus. Die Verarbeitung ist makellos und erscheint wertig. Endlich mal ein Amp, bei dem man die ab Werk gespeicherten Presets gut gebrauchen kann (ggf. noch etwas anpassen). Die eingebauten Effekte sind größtenteils gut bis sehr gut. Bei einigen vermisst man ein paar Regelmöglichkeiten. Die Akkulaufzeit ist sehr gut und der Ladevorgang geht schnell vonstatten.Der F40i ist wesentlich größer als der F15i und natürlich auch schwerer. Der Sound ist aber auch wesentlich erwachsener. Wer den Platz auf dem Tisch hat und die 90€ Mehrpreis bereit ist auszugeben, dem empfehle ich den F40i zu nehmen. Was in der Beschreibung fehlt: unten sind 2 Klappfüße vorhanden die als tilt back genutzt werden können.
Für mich der Beste Desktop Amp!

Édit 13/04/26 : L'ampli sonne vraiment bien pour son placement tarifaire. Je ne suis pas convaincu par l'IA de Mooer mais en revanche les fichiers MNRS qui sont comme des captures d'ampli réel sonnent monstrueux... Le Cloud ouvre des portes de folie. Du Vox AC30, Twin reverb, Friedman BE-OD, Soldano, Peavey 6505, Tone King Imperial...
Bref, je ne ressens plus aucune frustration. Alors certe, il n'aura pas la vibration d'un cab, mais c'est tout. La dynamique y est, la qualité y est.

Reçu il y a 10j et franchement, je le garde.

L'ampli est compact, léger, la sangle pour le transporter est bienvenue.
Le son developpé par cet ampli dans le cadre d'une utilisation solo (à domicile, en extérieur, en montagne) est super.

Inspirant, les cleans sont beaux, les edge to break up possibles, les distorsions sont ce qui m'a le moins convaincu jusqu'à aujourd'hui mais un son se travaille et je sais que je ne suis pas arrivé (pour ne pas avoir pris le temps encore, je suis honnête) encore à les exploiter.

Mais franchement, comparés aux Yamaha THR10X et THR30IIW que j'ai eu par le passé, il n'a vraiment pas à rougir et encore, ils possèdent X amplis (qui ne sont pas là pour faire la blague, loin de là) / X pédales / des IRs...
De quoi faire des nappes ambiants sans problème.

Le looper et la boite à rythme sont une belle surprise (60s x 8 pistes), le son est de qualité et vous pouvez empiler les pistes sans que ce soit bouilli => merci Mooer (parce que le Hotone Ampero II stage, ce n'était pas ça...).

J'ai acheté le footswitch F4 qui va bien avec, et malgré les critiques assez diverses, il s'appaire en 2 secondes, les fonctions sont intelligentes et c'est un plus indispensable pour les commandes Looper / boîte à rythme, changenment de banque et de preset. La combinaison différentes des 4 footswitchs (A / B / C / D / A+B / C+D / B+C etc) optimisent le tout puis quand on a pris le rythme, c'est fluide (pour ma part).

Alors certes ne vous attendez pas à avoir un ampli à lampes boutique avec ce Mooer (mais faut être un peu cohérent les gars quand même...), mais le son n'est pas en reste (comme tout, faut savoir régler un EQ, un compresseur, mettre le cab/IR qui va bien)

Ajouté à cela une intégration prochaine des profils NAM, une enceinte bluetooth qui n'a pas à rougir face à ma vieille Ultimate Ear Boom II, un chainage flexible, des IR's tiers possibles, des presets partageables dans la communauté Mooer, une batterie qui tient bien la charge, un écran tactile qui donne un accès rapide aux fonctions primaires. Une prise combo XLR/6.35mm derrière avec switch pour alimentation fantome 48V (branchement d'un micro possible ou autre instrument (guitare, basse...), des sorties XLR pour monitorings, un USB-C pour recording direct en 44.1Hz/24Bits (ce qui est suffisant).... pour 249€ ?
Bah je prends

Before buying it, I read reviews, watched overviews - either they were lies, or the people were incompetent... In general, what are the advantages - it is modern, a convenient application for editing effects/cabinets, good build quality, some effects can really be adjusted well.
- it is quite compact and has a nice build quality.

and now, unfortunately, about the downsides...

- The AI is complete nonsense... In the promotional videos, it was practically revolutionary, but alas. No matter how much I played with it, it produces something similar to what you asked for in about 10 tries... and then again, similar, but not quite the same. I was able to customize the effects more interestingly manually.

-the quality of the effects, the imitation of the cabinets themselves, is average, not bad, but not at a high level

- The worst thing is the volume, it's quiet. It's just catastrophically quiet... 40 watts? Seriously??? Any 15-watt amp plays 5 times louder. The sound is so quiet that you can play comfortably if you sit facing it. There is one built-in effect - classic distortion, which sounds louder than the others, but still weak. And what's the point of using just one effect?

In short, if you connect good external speakers to it, yes, the sound will be excellent, but then what's the point?! You can also connect a regular guitar processor that's much better and, importantly, much smaller, with pedals. In short, it's a very large guitar pedal, without pedals and with a built-in, quiet speaker. Someone picking up a guitar for the first time might be surprised by this device (like any first electric guitar, actually!), but for me, I understand that it's largely overrated. Alas, it completely failed to live up to expectations... A digital toy. Nothing more.

P.S. And yes, you can change the backlight color and make it blink. Oh yeah, how important that is for the sound))))))))
