The legendary high-gain amp choice of Slash, Rush, and the Red Hot Chili Peppers.

Developed by Softube — and available exclusively for UAD-2 hardware and Apollo audio interfaces — the Marshall Silver Jubilee 2555 plug-in is a thorough emulation of this ultra-rare amp, down to its four EL34 power tubes and hallowed high-gain preamp. It also offers powerful multi-mic sounds for a range of professional studio tones.

Introduced in 1987, the Marshall Silver Jubilee 2555 100-watt amplifier commemorated Jim Marshall’s 25th year in the amp-making business. With its striking silver Tolex and tastefully tweaked EQ, the SIlver Jubilee became a go-to for Slash, John Frusciante of Red Hot Chili Peppers, Alex Lifeson of Rush, and Joe Bonamassa.

Use your Apollo with Unison™ technology to track through the only authentic Marshall Silver Jubilee 2555 emulation — with no latency

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

Dial-in perfect studio amp tones with four different microphone combinations and two different mic types — Dynamic and Condenser

Fine-tune your guitar tones with 50 presets by legendary AC/DC engineer Tony Platt

Capturing the Silver Jubilee

Capturing the Silver Jubilee

To model the Silver Jubilee, Marshall loaned Softube’s engineers an original, all stock, Silver Jubilee 2555 head from its own museum. Pairing it with an era-correct 2551AV 4x12 loaded with Celestion Vintage 30 speakers, Softube thoroughly emulated the original amp’s unique three-mode preamp section, powerful EQ stack, and Triode/Pentode power tube operation.

Versatile Marshall Tones and More

Versatile Marshall Tones and More

The Marshall Silver Jubilee plug-in expertly models one of the most tonally versatile Marshalls ever made. Its Clean, Rhythm Clip, and Lead preamp modes offer a ton of textures, from dense crunch to singing sustain. And combined with the half power Pentode/Triode switch, you can dial in silkier, less aggressive 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 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 Four Expertly Placed Microphones

Mix Between Four Expertly Placed Microphones

Open up the plug-in’s Channel Strip section, and easily dial-in your sounds with two close mics and two room mics. Each mic features Level and Pan controls, 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 Silver Jubilee Tones

Unison™ Technology for Authentic Silver Jubilee 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.

A master class Plugin

The silver jubilee is my main amp and i'm really glad i can have it in this plugin format.
Please UAD bring this into a UAFX pedal !!

Absolutely fantastic plugin. Would give it 6 stars if I could. Already used it to record a cover of a song by The Darkness. Just gets that high gain rock tone without losing clarity. What really surprised me though is how awesome the clean channel is. For such a high gain amp it's so crisp and has a snap to it. Getting great Slash-like tones from it too!

Marshall® Silver Jubilee 2555

In my opinion, this is the BEST one of the Marshall amp emulators by far. I had given up on that idea until I played this one. I really think I can use this plugin for recording my album. Great Job AU!

Great Marshall Emulation

This is easily my favourite sounding guitar amp plugin. It really does emulate that great Marshall sound very well.

its alright, not bad

Im using it right now on a song also the plexiglass free plugin. They sound not bad. Ive never used the real thing to compare to give these plugins a 5. Goto admit though I still like my gt1000 better.

Great amp

This one is great, try putting distortion before the amp to heat crazy high gain tone - got my strat to sound like a metal machine.
The room mics are great too - so great I wish I could bypass the amp and use just the room mics on some sources

Very good amp model

This model captures the essence of the rare silver jubilee which stood out immediately when it was briefly released. With crisp highs (yet not too digital sounding) and easy to dial in classic rock tones it becomes a rather inspiring tool for songwriting, overdubbing leads and just playing for fun. The clean tones are also quite usable and certainly improve a direct-in guitar - perhaps not as versatile for clean tones (it is a Marshall after all) it has a lot of functionality and the control response is pleasing. The presets provide a good starting point and the multi mic interface gives a lot of options although I would like to be able to adjust mic placement a little more. I have mainly used it in Unison on a UA interface which really does feel like playing through an amp, but it works equally well in Pro Tools as an insert effect for re-amping. Although I have a number of amp, cabinet, and mic options available to me and prefer the organic aesthetic of capturing the actual movement of air, sometimes you just want to plug in and play or sketch an idea (or revisit a work in progress) and this is ideal for that. I spent a bit of time dithering as whether it was worth buying another guitar amp simulator, but the unison input was the tipping point for me and this has replaced any other sim as my go to for unison, re-amp and insert processing. Keep an eye on the sales and coupons from UA too!

As advertised!

Sounds like an 800 and has plenty of miking options built in. My most used guitar plugin by far.

As good as the real amp.

I tried the demo version and about 10 minutes later immediately went and bought it. It sounds and have exactly the same feel as the real amp. Simply amazing!

I had been eye-ing this plug-in for YEARS before pulling the trigger on it. I am a huge John Frusciante fan, so naturally, I try to emulate his sound. I had gotten close previously, but my guitar has some pretty rotten pickups and janky connections which proved challenging in trying to get any sound I want, let alone a specific musicians. I'm pretty spectical of plug-ins, too, just because they are so expensive and I always think, "well, they had to figure out how to make the tone so why can't I?"

I plugged into the Silver Jubilee plug-in, put on the dry clean pre-set... and I could not believe how spot on the sound was. It was a literal switch to get that high gain, thick funky Frusciante sound. And using the same setting with my BOSS ds-2 achieves the lead sound, too!

My favorite part though, is how motivating and inspiring it is to play with it. I have re-found the fun again of playing guitar. While it is expensive, I highly recommend this plug-in if you want a very realistic experience of experimenting with an amp head and mics.

Marshall fan NOW !

The Marshall Silver Jubilee 2555 is a must for any guitarist, from cool crisp cleans, to that Marshall sound of rock that I have heard on countless records. Simple controls, either for rhythm or leads, gainstaging or reamping. This is my new go to amp for tracking in the home studio. Marshall fan for life !

Great amp emulation.

I was looking for something that I could write with, and have live-no latency playing while recording. This does the job. And saves me from having to switch my buffer rate all the time, plus monitoring in my daw. Sounds great clean, as well as driven harder!

Sounds amazing and very accurate to the real amp. Out of all the Marshall amps, I’d say this is the most versatile one, and if you can only get one, get this one.

Aggressive, raw rock tones

Incredible amp sim — very meaty, punchy crunch tones! The near zero latency feature and Not worrying about crackles and pops is more than worth the price of admission. I own an axe fx 3 but often this is my goto first for ease of use and great tones. The curated cab and mic sim section make dialing in a tone very natural and more interesting than scrolling through tons of IR presets.

A real gem of a guitar plug-in

This was a no brainer for me: within the first 2 minutes of my demo I was sold on it. It gets so close to the real character of Marshall amps. The choice of microphones and room mic for natural room delay really makes this plug-in shine. Think smooth distortion with enough definition to play open chords (especially through ribbon and condenser mic emulations) and a delicious crunch that sits perfectly with nearly any genre of Rock. Hats off to Softube and UAD!
