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!”
– Tony Platt (AC/DC, Iron Maiden, Bob Marley)

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.

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.
G. Daddio
I like it lots
It’s very neato
A. Kolesnikov
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!
P. Jacobsson
More than rock'n roll
Nice clean, cruchy crunch and fat overdrive.

Marshall Madness
I am not a huge Marshall fan and have never owned a real one, but I just shut my eyes and listen. This thing is the missing link for my personal taste and has opened me up to new tones I had no idea about. I’m a Fender guy and love my 90”s Tone Master head, but there is no plug-in for that so I found JMP 2203 for my direct recording.
So fun to mess with all the different ways to get a cool sounds for recording.
I love it!

Super marshall
Super good. I love this sound. Thanks UAS

great
very good...

Best one among Softube Marshalls, but still way to go
If I have to buy a Marshall sim, I'd buy this one because it gives the most flexibility in regards to mic mix-and-match and its base sound is okay. However, Softube's emulation doesn't cut what I'd expect. Serious flaws with attacks and dynamics. Hopefully newer products will do it better.
