Marshall® JMP 2203
-
The Marshall that redefined the
sound of rock — again.Introduced in 1975, the Marshall JMP 2203 amplifier ushered in a new era of Marshall rock dominance. The JMP 2203 — which became the JCM800 in 1981 — offered varying degrees of intense, modern-sounding crunch and bold clean tones. Over the ensuing decades, the 2203 became a go-to for artists ranging from Jeff Beck and Andy Summers, to Tom Morello, Judas Priest, Slayer, and the Pixies’ Joey Santiago.
Developed by Softube — and available exclusively for UAD-2 hardware and Apollo audio interfaces — the Marshall JMP 2203 plug-in is a thorough emulation of this pioneering amp, down to its four EL34 power tubes and its sensitive, musical high-gain preamp. It also offers powerful multi-mic sounds for a range of professional studio tones.Use your Apollo with Unison™ technology to track through the only authentic Marshall JMP 2203 emulation — with no latency

Featuring the Marshall JMP 2203
Capturing the Ultimate JMP 2203
To model the JMP 2203, Marshall loaned Softube’s engineers an original, all stock, 1977 JMP 2203 head from its own museum. Pairing it with a Marshall 1960B 4x12 equipped with Celestion GT12-75 speakers, Softube thoroughly emulated the original amp, right down to its touch-sensitive preamp section and crunchy 3-D clang.
Versatile Marshall Tones and More
The Marshall JMP 2203 plug-in expertly models one of the most sonically distinct Marshalls ever made. Its simple layout, High and Low sensitivity inputs, and dynamic preamp offers a ton of textures, from dense distortion to powerful, attitude-laden clean/crunch sounds.
Voiced by a Legend
Producer/engineer Tony Platt has recorded some of the most classic 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 placements using his Platinum-approved, tried-and-true mic recipes. You can choose from 50 Platt-designed presets, or craft your own tones.
Mix Between Two Expertly Placed Microphones
Open up the plug-in’s Channel Strip section, and easily dial-in your sounds with a two channel mixer with five essential microphone options per channel. Along with individual Pan and Volume controls for each channel, you can tweak your tones further with global Input Gate, and three-band EQ with sweepable mids.
Unison™ Technology for Authentic JMP 2203 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 2203 amplifier — a feature found only on Apollo audio interfaces.
“A game changer for rock guitar, the 2203 is simple and direct. Always solid, punchy and crunchy...letting the notes sing clear and loud. This plug-in recreates that unique and individual response the 2203 has—and it misbehaves just like the real thing!”

Love this amp!
The Marshall JMP 2203 is my favorite of all of the amps I have tried from UAD so far. It has a good crunch sound and tons of character and can get very aggressive.

As real as it comes. Having grown up playing this amp, I'm so impressed with how accurate this represents the real thing. Being able to recall settings without having to mic up the real thing is perfect for someone like me living in NYC (the neighbors are grateful!)

Real Marshall Bite
Sounds great! Real Marshall bite and growl that I remember and loved back in the eighties for a fraction of the cost. Tone variations in the presets give me all the hard rock options I need. This plugin responds to changes in volume from the guitar just like the original amps did too. The microphone options take the tone sculpting to a new level of accuracy too. Great job UA peeps!

The sound of Rock 'N' Roll.
This is the closest to the real thing that I've tried.
It just does what I expect it to do and does it brilliantly. A must have basic amp.R. Gregory

Sounds like a Marshall!
Cuts through the mix!M. Shpakov
Eins der besten Gitarrenverstärker-Plugins!
Sehr klarer und gut klingender Gitarrenverstärker. Perfekter Sound mit allen Presets. Unterstützt Abtastrate bis 192 kHz! Ideal für Echtzeit-Performance.

Great sounding plugin!

Killer Rock Amp!
Sounds exactly like the picture! Lol!
Seriously, with the miking options and the realistic hardcore sound, it's almost impossible to tell if you have one of these beasts in your live room miked up and roaring, or if it's the plug in! Super responsive and makes my 1970 Les Paul come alive!S. Simpson
Love it
It’s killer.. I have several sims from different companies and honestly in my opinion the UAD sims are pound for pound the best overall. Add some Ocean Way studios and you’re good to go.

Отлично звучит!
Наиболее универсальный усилитель из всех Маршаллов у UAD, можно настроить практически любой звук, идеально подходит для создания аранжировок
A. Kolesnikov
Отлично звучит!
Долго сомневался, какой именно усилитель из Маршалов купить, много тестов провел, но именно 2203 показал себя самым универсальным. Очень хорошо реализована настройка и выбор балансов микрофонов, можно получить практически любой звук. Фантастика!

More than rock'n roll
Nice clean, cruchy crunch and fat overdrive.
