Marshall Plexi Super Lead 1959
There is perhaps no other amplifier more vital to the history of rock & roll than the Marshall Plexi Super Lead 1959. We took Marshall’s own museum-piece Plexi (a pristine model from 1967) under extremely careful security and supervision, and modeled each and every component to produce the most textured, detailed software version imaginable. At any setting it responds exactly like the hardware, and it’s sensitive to your playing style like you wouldn’t believe.
Extreme sound quality and authenticity
Component-modeled for the most accurate possible recreation of Marshall's own reference unit.
AC/DC's own engineer
Cabinet responses recorded at Kore Studio, London, with mic selections and positions by AC/DC engineer Tony Platt (Highway to Hell, Back in Black).
The guitar hero's choice
Angus Young, Jimmy Page, Graham Coxon, Johnny Ramone, John Frusciante, Slash, Pete Townshend, Eric Clapton, Jimi Hendrix – they all used a Plexi Super Lead.

The history of Rock & Roll
The Plexi’s design was essentially commissioned by Pete Townshend of The Who, looking for more power, volume, and grunt as true high-voltage rock began to explode in the mid ’60s. Eric Clapton traded in his ‘Bluesbreaker’ combo for a Super Lead when he founded Cream in 1966. Jimi Hendrix, for goodness sake, played a Super Lead at Woodstock. Need we say more?
The first Marshall full stack was created for the Plexi. Initially the super-powerful, 100 watt amp was paired with a huge 8x12 speaker cabinet, but soon the preference shifted to two 4x12s, one straight and one angled. It’s hard to overstate how much of a cornerstone this amp is. Rock simply wouldn’t look or sound the same without it.
Your own personal legendary engineer
We retained the services of Tony Platt, engineer for AC/DC on some of the most face-meltingly rocktastic albums of all time, to capture impulse responses from a perfect era-appropriate 1960BHW cabinet with a variety of expertly placed vintage microphones. Nothing comes close to the mix-ready magic of these sounds. We built a world-class engineer, who knows the amp like an old friend, right into the plug-in.
The channel strip
In addition to the amp itself, the plug-in provides a complete setup and workflow for getting mix-ready sounds. Three different microphone combos – FET, Valve, and Dynamic – were recorded by Platt at Kore Studios in London, and the results can be blended and tweaked in the side panel of the plug-in.
Each microphone has its own volume and pan settings, just as you'd expect working in a top-class studio, so you can mix your own ideal sound right there in the plug-in. This is more than just an amp sim. It's a complete workflow for an amazing mix-ready guitar tone.
Detailed and versatile tone
Two channels, a lead and a rhythm, each with both high and low gain inputs, can be combined (or 'jumped') for a wide-range of sounds. Go from a warm, gritty twang right up to a searing wailing rock god solo scream, and never let The Man stand in your way.
Angus Young played one in AC/DC. Jimmy Page played one in Led Zeppelin. Graham Coxon, Johnny Ramone, John Frusciante, Slash. The versatility of the 1959 (‘1959’, by the way, being a model number rather than a production year), and the ease with which it produces fantastic harmonically rich sounds, defined a genre and a movement.
Don’t compromise with lesser rigs. Don’t put up with pretenders. Get the one and only Plexi Super Lead 1959, and ground your tone in pure rock.
Perfect for Amp Room
Plexi Super Lead 1959 comes with modules that are fully integrated into the Amp Room ecosystem and sound exactly the same as the native version of the plug-in. If you already own Amp Room, you definitely need this amp.
Amp Room is the pro audio guitar and bass platform, designed with sound quality as top priority. It’s just like having a real amplifier with a miked up speaker cabinet in a high-end studio – with the added convenience of more options to patch in any kind of studio tool you need anywhere in the chain.
This product supports
We love VU meters, Bakelite knobs, and analog quirks. But we want modern precision and workflow. The answer? Softube Extended Features. Easy-access panels with the innovations you need close at hand.
Softube & Marshall: A partnership based on sound quality
Softube’s first prototype was a hardware DSP box running a Marshall amp model and a loudspeaker model. This attracted Marshall’s interest and led to a successful long-term partnership between Softube and Marshall. Softube is Marshall’s exclusive software partner, and Amp Room comes with the only amps and cabs available in software form that are officially licensed and endorsed by Marshall.

All Softube products require a computer with appropriate DAW host software (none of which are included).
Versions from 2.5.38 and newer of the Softube plug-ins have the following minimum requirements:
All native versions
- Mac OS X 10.13 up to 12
- Windows 10 and 11 64-bit

- Screen resolution larger than 1280x800
- 8 GB RAM or more is recommended, as well as at least 8 GB hard disk space for installation (individual plug-ins take less space, while sample libraries may require additional disk space)

- iLok account
- Internet access for downloading installers and managing licenses
- iLok generation 2 and up, if you intend to use an iLok key for authorizing your plug-ins (note that a physical iLok USB key is not a requirement)
In theory, any 64-bit VST, VST3, AU, or AAX (Pro Tools 11.0.2 or higher) compatible host application should work. However, due to plug-in host differences between DAWs - and our own rigorous testing standards - we only officially test our plug-ins and instruments in the most recent versions of Pro Tools, Logic Pro, Cubase, Ableton Live, Studio One, Reaper, and Cakewalk. Softube plugins are not tested in non-listed systems, but they most likely work as long as the system requirements are met. We cannot guarantee a solution for issues in unsupported systems.
Note: We have checked the basic functionality of our plug-ins, and Softube Central, under Apple Rosetta 2.
With regards to the different VST formats, we strongly recommend using VST3 as some of our plug-ins have features that are not present in the older VST format. Supported sample rates: 44.1, 48, 88.2, 96, 176.4, and 192 kHz, in both mono and stereo. The most recent maintenance release of your DAW application is recommended. AAX DSP is not currently in active development. TDM/VENUE is no longer supported (old downloads are available on the Legacy Installers page).
Find the Softube installer you need both Softube Central and individual plug-ins.
AAX DSP version
- For AAX DSP you need to meet the above requirements for the Native versions. You also need to have an Avid HDX processing card. For plug-ins available for AAX DSP, see Which Softube plug-ins support AAX DSP?
