Marshall Silver Jubilee 2555

The amps in the Silver Jubilee series were based on the 2203 and 2204 models of the JCM800 series but with a variety of clever new features. The Silver Jubilee 2555 had an innovative and unusual preamp section that gave it higher gain and a somewhat darker and smoother sound than the JCM800. The preamp circuit had three gain modes: Clean, Rhythm Clip, and Lead.

The EQ section also set the Silver Jubilee apart from other Marshall amps with its much wider range of tonal variety. It was the first Marshall amplifier with power amp tubes that could be switched from their normal pentode operation mode into triode mode. The power amp's output was cut in half with the power amp tubes working as triodes, making the power amp distortion silkier and less aggressive. All of this has been modeled with the highest precision in the plug-in.

Producer and engineer Tony Platt, who recorded some of the best Marshall tones ever committed to tape on some of the most rocking albums of all time – AC/DC’s Highway to Hell and Back in Black – masterfully captured the sound of the 2551AV Silver Jubilee series cabinet equipped with 4X12” Celestion Vintage 30 speakers.

Platt recorded the cabinet with classic dynamic and condenser microphones, all carefully selected to give a wide variety of tones and positioned to sound fantastic when used in combination with each other. Nothing comes close to the mix-ready magic of these sounds. We built a world-class engineer right into the plug-in.

Open the side panel of the plug-in, and a channel strip appears with options to help you blend and tweak your sounds until they’re mix-ready. The Input Gate, which you can adjust to suit your playing style and your guitar’s output, reduces unwanted noise and gives a cleaner and tighter recording. Use the Master Out to set the overall output level of the plug-in without affecting the sound.

Choose between condenser or dynamic mics with Mic Select and use In to activate or deactivate each microphone channel. Use Pan to place the microphone channel where you want it in the stereo panorama. A delay line has been added to Room Mic 2 so that the sound from this microphone can be delayed more than it was in real life, and the Room Mic Delay fader sets the time of this delay.

There is also feedback loop in the delay line that sends the signal from the microphone back through the cabinet where it’s picked up again by the microphone and so on, and you can set the volume in this feedback loop with the Feedback knob. With all of these options, you can mix your ideal sound right there in the plug-in.

Silver Jubilee 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.

Softube & Marshall: A partnership based on quality sound

Our first-ever prototype was a hardware DSP box running a Marshall amp model and a loudspeaker model. That got the attention of Marshall Amplification and led to a successful long-term partnership. Marshall Cabinet Collection comes with the only software amps and cabs officially licensed and endorsed by Marshall.
