Marshall® Plexi Super Lead 1959

Unison Enabled





The legendary sound of rock, captured in all of its power and glory.

The undisputed alpha dog of rock and roll guitar amps, the Marshall 1959 Super Lead amplifier is as legendary as the music it helped create. From Jimi Hendrix to Jimmy Page to Eric Clapton, the “Plexi’s” punishing melange of snarl, sustain, smoothness, and raunch defined the sound of rock.

Developed by Softube — and available exclusively for UAD-2 hardware and Apollo audio interfaces — the Marshall Plexi Super Lead 1959 plug-in is not only an expert emulation of this 100-watt British classic, right down to its EL34 power tubes and hand-wired circuit, it offers uniquely powerful multi-mic sounds as well.

Now You Can:

Use your Apollo with Unison™ technology to track through the only authentic Plexi Super Lead emulation — with no latency

Re-amp previously recorded tracks with any UAD-2 hardware

Dial-in perfect studio amp tones with three different microphone combinations — FET, Valve, and Dynamic

The Only Authentic Emulation of the Perfect Plexi

The Only Authentic Emulation of the Perfect Plexi

In an effort to capture the ultimate Plexi sound, Marshall offered the talented developers at Softube a bone-stock, pristine 1967 Super Lead from its own museum. Pairing it with an era-correct, broken-in Marshall 1960BHW 4x12 cabinet, Softube emulated all of the Super Lead’s idiosyncratic “ghost note” overtones, as well as the ability to “jump” the amp’s inputs to dial-in a wealth of high-powered tube tones.

Voiced by a Legend

Voiced by a Legend

Producer/engineer Tony Platt has recorded some of the most quintessential Marshall tones ever committed to tape — most notably AC/DC’s landmark albums, Highway to Hell and Back in Black. Softube enlisted Platt to capture exquisite cabinet and microphone simulations using his Platinum-approved, tried-and-true mic recipes. You can choose from 50 Platt-designed presets, or craft your own tones.

Open up the plug-in’s Channel Strip section, and easily dial-in your sounds with Panning, global High/Low EQ, and Level control over each microphone, allowing precision fine-tuning — during tracking or mixdown. No matter the genre, or type of guitar, you’re afforded tons of tweakable options, from pin-point single miked tones to roars of glorious room ambience.

Unison™ Technology for Authentic Plexi Tones

Unison™ Technology for Authentic Plexi Tones

The interaction of your guitar’s pickups to an amp’s front end is crucial to capturing the tone and feel of the amplifier. With UA’s Unison technology, Apollo user's guitar pickups will see the exact impedance load as if they’re plugged into a vintage Marshall Plexi — a feature found only on Apollo audio interfaces.

J. von Matt


Rock n roll

What you can expect from Marshall?

All the same is included here!

Pure Marshall!

Atrongly recommended and used!

D. James


Sounds amazing with my Gibson!

Just plug in to your interface and bam! Instant magic. Then start dialing in those tones...perfection. Great job, UAD!

s. smades


pretty much what you pay for

nothing stellar, nothing terrible. what you think this amp would sound like, Is probably what it does sound like



Great For Solo’s

The amp gave the guitar solo some real ‘feel’ to it

R. Woods


Pretty Good

I can’t compare this to the real thing because I’ve never owned it but considering I’m plugging my guitar into a computer this thing is remarkable. Not only does it sound great but it’s versatile and very responsive to guitar volume settings and playing style. Very happy with this plugin and being able to use it in stereo is the cherry on the cake

J. Sivusalo


Thats it!

It looks like AC/DC and sounds like AC/DC, so ..I take it :)

N. Garcia


Great amp!

Well I have recorded for a feature film and a short, and it's simply really a great amp. Thanks uad, we need more amp like fender twin, fender bassman. Bogner....

h. hyakkoku



This is it is perfect, I love Marshall.

T. Tracy



I'm knocked out by this Marshall Plexi plugin, it ads some serious crunch for those songs that need the Marshall sound. I've always loved the Fender tube amps and this fills out what I can't get from my 66 Deluxe Reverb. You guys at Universal Audio have made my sonic world a more beautiful place!

P. Herrick


Knock your socks and sandals off

Unlike myself this amp is truly high quality and has that way of sounding like a Marshall that only a Marshall can Marshall. Enjoy it, don't stay bored.



Sounds great

I’m really enjoying the complexity of the Plexi tone and being able to edit the mics and placement
Could you please steal an old knob and put it on the mid control and make that an option? Who thought it was a good idea to leave it missing, like that makes it more “real”

G. Bonfiglio


Fantastic sound

Thanks UAD, this is an amazing plugin, with a superb sound. Perfect for Pop and Rock music

C. Wieszczek


Less than a feeling

I'm not feeling these digital amp emulations. Played a Strat into the system and monitoring via headphones. Definitely not the same experience as plugging into a real amp. A great amp is inspiring, these are sterile. If there is a recipe making this work I wish it were documented. To me, the old Rockmans were better. I Don't find the interaction of guitar with the system realistic. This plugin does vary in tone sculpting compared to the others. I also expected the presets used in the demo to be included but are not.

R. Gregory


Marshall tone!

Warm tone! As close to the real thing I've found!

B. Ullman


Big Bad Nasty

Fantastic plugin. I will never own or even have chance to play a 59’ Plexi, but I grew up playing a Marshall & this feels similar yet way more HUGE!! Don’t believe me, try your demo. You might need it then tho, haha be careful. Rock

I. Bandera


Molto bello!

Come detto per il jmp 2203, le simulazioni di amplificatori uad / softube sono le migliori.
A differenza delle simulazioni Brainworks con la quale non mi ci trovo per niente, queste sono le più reattive e fedeli che abbia mai sentito.
Sono in possesso oltre che di questo plugin, anche del jmp 2203 ed il Silver Jubilee, uno più bello dell'altro.

V. Pirov



Nice! very good!

R. Hortensius


Great Marshall Sound !

Used just this Plexi with very little processing for this instrumental.

m. buchbinder


Wow! This Amp is awesome!

A great addition to my Amp collection. Looks great, feels amazing and sounds as close as you gonna get to the real thing. Great job Softube and UA, keep it coming and inspiring.
