Nembrini Audio was born from the experience of Igor Nembrini, who has been involved in the creation of the most famous guitar amp plugins on the market for more than ten years.

Our emulations start from the exact digital reproduction of the analog circuits but are then finely tuned by ear to obtain maximum fidelity to the original sound.

Nembrini Audio is specialized in digital reproduction of analog saturation circuits.

The dynamic behavior of each individual component is carefully modeled and tuned by ear to always achieve the most musical and creamy saturation in the digital world.

Nembrini Audio does not produce musical softwares but musical instruments suitable for every modern musician in search of uncompromising quality.

Our goal are products that sound well with any setting and situation to let the creativity of the musicians, producers and mixing engineer flow.

2 in 1!

For me the first convincingly sounding, reacting and behaving Plexi simulation, which I've heard within the last 22 years.

In fact this plugin are 2 amps in one, a regular 1959 Super Lead and a EVH modded Brown Sound Plexi, which is some sort of beefed up Plexi with more, slightly fatter punch, gain and - most important - even inceased harmonics reproduction. Also important for this sound is the Variac, which reduces power voltage and therefore also internal voltage. The result is more saturation but less headroom.

One of the advantages of the EVH mod for me is, that the modded SLP still sounds like a real Plexi and not already like a JCM800, which happens with some other mods.

The 6CA7 power amp tubes sound - more or less - like a hybrid between an EL34 and an 6L6, which means, that this amp on the one hand definitely sounds like a (very good) Plexi but also has some more, very musically sounding upper mid and treble transparency as well as a more intense bass than you might expect from a typical EL34 Plexi. Even a little bit similar to a modded Bassman or JTM45, so the Standard voicing is - in my opinion - the perfect amp for Classic Blues Rock to Hard Rock. The Brown Sound Mod also adds some mids and is the better choice for heavier, fuller bodied late 70's, early 80's tube overdrive tones, although also the Brown Sound Mod doesn't change the amp to a modern high-gain amp.

The special G12M / D120 cabinet is an interesting thing, especially for the Brown Sound mod, but I personally also would have liked an additional G12M or G12H 412 cabinet for the standard amp, maybe instead of the Soldano or of one of the V30 cabinets. On the other hand you anyway can load external cabinet IR's and even mix them, so this is not really a big disadvantage.

One thing I've noticed is that - especially in Standard mode - this plugin reacts much more sensitive to guitar, pickups, pick attack than most other amp simulations, but also to the used cabinet IR's. Very similar to the real amp, but without it's wall breaking loudness.

Especially the linked channels allow a very intense control over gain and tone, but therefore not all possible settings automatically sound right or great, also because this amp (simulation) reacts very interactively with all the rest of the used gear. On the other hand you have an excellent control over bass, mid, treble and - of course - gain.

So once you have learned how to tame and adjust this sonic beast properly, this plugin can give you these absolutely awesome, outstanding, iconic tones, which you hardly will get from any other amp (simulation) and which we all know from a lot of legendary recordings, extremely well.

My personal - in this quality long overdue - guitar plugin of the year! (Or rather of the decade?;-)).

Thank you very much, Mr. Nembrini.

One of the best, most naturally sounding overdrive pedal plugins, I know.

Sounds very convincing, if you look for these typical "Dumble-in-a-Box" Klon Centaur tones.

Works great in front of (too clean to slightly overdriven) vintage amp simulations. A perfect companion for Tweed amps, for vintage Vox or Marshall amp, but not only, also works great in front of more modern voiced amp simulations. Even sounds very good alone or only with an additional cabinet IR.

My personal perfect combination is this pedal in front of the Nembrini MRH159, all you need for almost every kind of music.

An OCD simulation in this quality from Nembrini Audio also would be nice, I think. If possible, with different voicing options, eg. between the V 1.2, 1.3, 1.4 and 2.0 GE versions.

There are a lot of Vox simulations available, but up to now they did not really convince me very much, even less as I've been playing a real Vox for years - decades ago.

This one is - in my opinion - not only the most authentically sounding simulation of this iconic amp, I also like a lot that it includes the authentic 3 channels, 6 inputs plus Reverb and the Vibro-Trem circuit.

I totally had forgotten how great a Vintage AC-30 really sounded and still today sounds. So does this DC-30 simulation. Playing immediately sounded very familiar and resulted in very convincing tones - at (bed)room level - which has been absolutely impossible with the - in reality - incredibly loud real amp due to the vintage single volume design of the circuit.

The Vib-Trem channel is great for typical clean(er) Shadows or Beatles' guitars but also for these typical late 60's Italo-Western soundtrack guitars with a lot of reverb and tremolo. The built-in Vib-Trem unit sounds incredibly good and unique, very different from most pedals. Retro tube tones to die for.

The Normal channel is great for these typical warm, sweet Brian May tones, Normal and Brillant channels both can give you typical Rory Gallagher or Status Quo tones, but not only, Ritchie Blackmore also played AC-30's before Deep Purple Mk. II (Think of "Hush" or "Concerto for Group and Orchestra", Jeff Beck and Jimmy Page also in their early Yardbirds years, as well as the - in my opinion - completely underrated Terje Rypdal and a lot of other great players.

The additional Link/Bridging option here extends the sonic possibilites and is especially very useful for overdrive tones.

Basic tone is excellent, but what I really like is that these very unique, vivid Vox harmonics sound very accurate here, the gain range is very exactly the one of the real amp, also the reaction to attack is very authentically. My only complaint - if one - could be that treble in the bright channel at higher gain and treble settings may sound a little bit too sharp and still a little too digital for my taste. The real amp also is capable of a lot of very intense treble, maybe even too much at certain settings, which also can sound very biting, even too sharp, nevertheless the authentic treble tube breakup still shows some more sweetness at the same time, which I miss here a little, compared with a real AC-30. Nevertheless too intense treble sharpness easily can be compensated with the Cut (Reverse Presence) tone control as well as with the additionally built-in harshness control here.

But this is complaining at a very high level, most other AC-30 simulations, I know, are miles away from the beautiful, in general very convincing, authentic tones of this simulation. Concerning all other sonic aspects this simulation feels and plays very much like the real amp.

As the AC-30 has a rather mid-scooped sound, it also works well with pedals with some mid boost, Tube Screamer, SD-1, OCD, Klon Centaur, Zendrive are a good choice. My personal favorite is the SD-1, as it's tone additionally adds more harmonics than eg. a Tube Screamer, which even increase the already great harmonics of the amp. (If you know "Ambiguity" from Terje Rypdal (Chaser album from 1985), these are exactly the tones you get from this combination.).

Alternatively also an equalizer pedal in front can be a good choice to add some mids, without altering the amp's tube tone itself too much, which also makes the tone more similar to a Plexi, but generally the AC-30 always sounds sweeter, more harmonious, less rough than a Plexi, with more singing sustain but less dirt at higher volume settings.

The built-in cabinets sound good, the Vox cabinet of course sounds great, but also the Twin cabinet with the JBL's sounds very interesting, a quite different, but convincing voicing, but the simulations also works well with a lot of other speakers/cabinets.

An AC-30 simulation in this quality has been long overdue, as this amp is - in my opinion - even today one of the best sounding allround amps with a very unique tone, which you hardly can get out of any other amp. (Or out of any other amp simulation - in this case.).

In the future a Marshall 1959/1987 Plexi simulation in the same quality from Nembrini Audio would be highly appreciated from me, but also a Hiwatt DR-103 or maybe a Dover DA-50 simulation.

But at the moment this plugin certainly will become one of my favorite amp simulations. Great work.

Tones to die for.

Simply the best, most naturally sounding and reacting simulation of an EVH amp, I know.

Great, convincing tones, authentic feeling and reaction of a real tube amp while playing, good built in cabinet selection, but also the IR loader works fine. The Cleaner is - additionally to the regular tone conrtols a good idea, as it allows reducing (too intense) low end or high end sizzle. In most cases it anyway is not really necessary, as the plugin anyway sounds top notch, but it can be used for some additional tone shaping as well.

To be honest, Rectifiers never have been my favorite amps. But this plugin sounds excellent. It also seems to sound a little bit different to some other Dual Rectifier simulations, which I've heard or tried up to now.

I've noticed a more dynamical reaction, a generally more aggressive, more transparent sound with less fender-like politeness and compression, which I noticed on other Rectifier simulations, instead with more of an almost British voiced directness and rawness, nevertheless the tones still remain typical, excellent Rectifier tones.

Apart from a lot of other great tones for me the real secret weapon of this plugin is - really surprising for me - the Pushed voicing of channel 1. It not only creates the expected decently crunched Tweed amp tones, but at higher gain settings you also get some (for a Mesa Boogie) astonishingly great sounding and very dynamically reacting JTM/JMP Plexi tones, with the additional advantages of a really good working tone control plus even more fine-tuning options due to the very effective Bold/Spongy and Tube/Diode switches. Maybe with more of this typical Mesa Boogie low-end, but this is not necessarily a disadvantage, and also can be reduced easily if wished by reducing Bass.

This voicing alone would be worth the plugin. In fact it was the main reason for my purchase.

I also noticed, that the 3 different voicings of channel 2 and 3 seem to be better balanced than on some other Rectifier simulations, so the different voicings also seem to be better usable, as they all have their different, special qualities.

A great sounding all round amp.

NA 808 Overdrive Pro
Reviewed By nonewwavenofun

This is probably one of the best sounding Tubescreamer emulations - can get a nice mild overdrive or can turn the gain down and the volume up to tighten up guitar amp plugins. The only issue is that I can't resize the GUI - it's absolutely massive on my laptop, which feels silly for a VST with three controls. I'd give it five stars if the GUI was resizable.

Although I really like most Nembrini amp simulations, this one leaves very mixed impressions to me.

On the one hand the Clean channel (including the Crunch voicing) sounds - as expected - excellent, unfortunately the Boost channel did not really convince me. Sounds like a Soldano, but – especially if compared to some other Soldano simualtions, I miss a lot of this typical midrange punch, while treble sounds much too sharp, too thin and shrill for my taste.

I tried a lot, reducing input and output level, only using Normal mode, but as soon as I adjust Treble and Presence to medium settings or higher, the tones get some – for my taste – much too intense, unharmonious sounding sharpness, but if Treble and Presence are reduced, the tones start sounding too dull and muddy.

Using a 412 with G12M speakers reduces the problem a little, but this cannot really be a convincing solution.

A Soldano has some treble bite, no doubt, but the one here sounds too harsh and unnatural to me, even more, as some more intense mids also seem to be missing.

A similar experience I also made with the Nembrini Sound Master Custom plugin. Fantastic sounding Clean channel, but unfortunately also a too sharp, too thin, too shrill sounding Overdrive channel.

A little bit disappointing, especially if compared with some other, really great sounding Nembrini amp simulations. So I think, the Boost channel really needs some upgrade, to sound convincing. Then this also could be fantastic sounding plugin. Until then I rather prefer using some other Nembrini amps.

Whenever you play an incredibly good and authentic sounding guitar amp sim or a guitar pedal sim, that just nails the tone, so that you cannnot help start grinning like a Cheshire cat while playing, chances are extremely good that Mr. Nembrini has programmed them. (My experience.).

He seems to have the unique talent, to not only making his simulations sound authentic, but also they behave and react like the real gear, so that you also can play them just like the real world originals.

The Eddie Kramer / F-Pedals designed Phazevibe just sonds great and very musical. No only, but also recommended - of course - for Hendrix-fans, nevertheless you get a lot of different, more or less timeless great tones out of it, which you maybe also can get with an individual, more complicated effects chain, but alone for this you will need a very good sounding vintage phaser, a good sounding wah and / or auto wah, an equalizer, an authentic univibe and a good Leslie-rotary simulation and then you just have to start adjusting everything right and need to know how to mix all this properly together, to get some comparable sounds. Phazevibe offers you these kind of (legendary) tones summed up and yet widely controllable with just a single or at least some few knobs.

The vivid, pulsating Phazevibe tones are a good combination - and alternative to the usual clean (tremolo/vibrato plus) spring reverb standard - especially with a good, cleaner adjusted Plexi or Tweed amp sim, but also work fine at higher gain settings and with more modern amp designs. Also they are, I think, not only useful for guitars. Also eg. Bass, Organ, Synthesizers, ... really can sound fantasic through it.

The original pedal is great and really unique. And so is this plugin! The rack version even allows some more additional tweaking options, which the real pedal doesn't offer.
