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.

Capturing the Ultimate 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.

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.

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.

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!

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!

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!

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!

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.

I never imagined that I would feel the pleasure of playing with this marvel, it sounds the same as the original, and even better.

Marshall sound at its finest.

The Marshall JMP 2203 plugin is by far the best sounding amp plugin I’ve ever used in my DAW. It’s been a real pleasure working with this plug. If you close your eyes, it sounds like the real deal. Thank you Softube for another incredible plugin. A+++
