The 50W Marshall JMD50 digital guitar amp head, offers a balanced mixture of classic all-tube power and studio-quality effects, all wrapped up into an amazing Marshall package. The JMD50 amp, part of Marshall's JMD:1 series, uses this technology to create a vast library of tone styles firmly rooted in the foundations of Marshall amplifiers. The Marshall JMD50 head provides interpretations of unmistakable classic sounds and a variety of combinations. These are delivered in 16 easy-to-access topologies, replicated from component level information for a truly natural and interactive playing experience.

The digital and tube combination for JMD50 50W amplifier head
After working closely with the digital experts from Softube, Marshall created a digital and tube amplifier solution that offers a multitude of tones, allowing the guitarist to experience and experiment with a variety of preamplifier topologies from Marshall's history, all in combination with the power and warmth of a traditional EL34 based power amp stage.

The Marshall JMD50 head is a compilation of amp tones created by Marshall over the last 45 years, from a vintage plexi, to a JCM 800, all the way through to a high gain JVM. For instance, have you ever wondered what a 1974 preamp would sound like through a monster 50W tube stage with a hint of reverb for ambience? The Marshall JMD50 amp lets you do that. Do you want to try a Guv'nor pedal through the power of a Marshall 50/50 power amp and a hi-fi style delay? The JMD50 amp head lets you do that too. What makes the JMD50 head so adaptable and versatile, is that it is completely programmable, allowing you to store your sounds and then access them again with ease.

Marshall's delicate balance between technology and tone
Instead of trying to mimic the overall sound of an amplifier by simply creating a copy of the tone that is generated, the JMD50 takes into account every nuance of a preamp. Not only recreating the tone accurately, but also how the unit reacts when you make adjustments to the equalization.

The familiar Marshall front panel is extensive in features and easy to navigate. Selecting the preamp sound you want is as simple as choosing one of the 16 sounds from the rotary preamp control. This section has been divided into 4 separate groupings for ease; Clean, Crunch, OD, and Lead. From there, all you have to do is set up your EQ section and choose and adjust which of the high-quality effects you desire. Storing this sound is just a case of holding down one of the 4 channel buttons on the amp or saving to the foot controller, storing everything from the EQ to the parameter of chosen effect. So now your able to go from a classic low-wattage tube sound with a hint of reverb, to a traditional high-gain '80s lead sound with delay for solos, to a scooped-out metal sound, incorporating chorus with the press of a button.

Marshall Custom FX
The effects section of the JMD50 amp head gives access to a host of popular effects, all of which have been tailored specifically to give the best possible response. Not only are the effects redesigned, they are also fully adjustable to be as subtle or extreme as you wish. The effects are divided into 3 separate stages, Modulation, Delay and also an independent Reverb.

Marshall Functionality from studio to the stage
With the included footswitch, the Marshall JMD50 can work to its full ability. The foot controller enables the player to store 4 sounds across 7 banks, giving the option of storing 28 sounds and the ability to access any of them at any given time. When sounds are stored in the foot controller or the amplifier it recalls everything apart from the master volume and the Presence. MIDI switching capabilities also allow the user to control the amplifier remotely, and add the possibilities of up to 128 configurations. Effects loops allow the player to add in any personalization they require, and the balanced line out contains the best Marshall cabinet simulations for recording a multitude of tones directly.
