The Marshall JMD502 is a 50 watt combo amp, with a balanced mixture of classic all-tube power and studio-quality effects, all wrapped up into one amazing Marshall package. The JMD502 uses this technology to create a vast library of tone styles firmly rooted in the foundations of Marshall amplifiers. The JMD502 guitar amp 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 JMD502 50W amp
After working closely with the digital experts from Softube, Marshall created a digital and tube combo amplifier solution that offers a multitude of tones, allowing the guitarist to experience and experiment with a variety of pre-amplifier topologies from Marshalls history, all in combination with the power and warmth of a traditional EL34 based power amp stage.
The Marshall JMD502 amplifier features a compilation of 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 100W tube stage with a hint of reverb for ambience? JMD502 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? Marshall JMD502 lets you do that too. What makes JMD502 so adaptable and versatile, is that it is completely programmable, allowing you to store your sounds and then access them again with ease.
A 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 Marshall JMD502 guitar amp 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 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 four 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 quality effects you desire. Storing this sound is just a case of holding down one of the four channel buttons on the amp or saving to the footcontroller, storing everything from the EQ to the parameter of chosen effect. So now you're 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.
The effects section of the JMD502 guitar amp gives access to a host of popular effects, all of which have been tailored specifically to give the best possible response in the Marshall JMD502. 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 three separate stages, Modulation, Delay, and also an independent Reverb.
Functionality from studio to the stage
With the included footswitch, the Marshall guitar amp can work to its full ability. The footcontroller 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 footcontroller 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.

I love this amp. After going to guitar center and trying out every tube combo they had in the $500-$1000 range, I ordered this amp from gc.com and I am so happy with it. I went in thinking I wanted a Fender and I felt like I was paying more for the name than the sound. They sound really nice but they dont have enough options. I ended up purchasing a vox ac15c1 but I took it home and ended up returning it the next day. I came across this marshall jmd501 online and it sounded like everything I wanted: a 12" tube combo with some decent wattage. But I was surprised to find that it emulated every marshall amp ever produced, has built in effects, and a 6 button footswitch. So I gave it a shot. I took the vox back and had to special order the marshall. I had no amp for almost three weeks I was going crazy. So anyway, the amp finally showed up at my front door, I pulled it out of the box, and now I love it. The amp has enough power to get pretty loud. It's probably not going to compete with a marshall stack but it does get loud. And it sounds VERY good loud. The tube technology is amazing (I had solid state prior to this amp). The amp modeling provides lots of flexibility. You can get a great blues, jazz, clean, rock, metal, etc tone. You can play it with humbuckers or single coil and it really brings out the tone of your guitar nicely with some decent volume. The effects are a definite plus as well. They are not as adjustable as a good set of stomp boxes. But I'm not super picky with my effects as long as my overdrive sounds nice (the amp provides this) and I like to have a good wah (already own). So in a perfect world the effects would have a little more adjustability. But they get the job done. And if you're dying for more volume, you can always connect it to a speaker cabinet and get some more volume. A+ for this amp, it's a GREAT buy. I love it, i'll never own another amp other than a marshall ever again!
To be fair, this amp should be compared to other digital amps. No, it doesn't sound and/or feel EXACTLY like a tube amp, but its pretty close. It has the glassiness and depth of tubes and maybe not a 3D sound, I'd say 2.5D. The speaker is a weak point and needs a lot of break in to round out the tone. When you audition this amp, make sure you turn all tone controls to 0 (fully counterclock wise) and first add treble, then middle, and then bass. This makes it easier to dial in the tone you like without too much fizz, flub, etc. The only gripe, and this is because its digital, is that there is a bit of high end "fizz" that is sometimes hard to dial out on certain models (but the noise gate helps here) and sometimes pinch harmonics are hard to coax out of your guitar. All that again depends on the amp model and corresponding eq. Compared to the Vyper, which is a lot cheaper, the JMD is a beast and head/tails above the Vyper in tone and feel. The Vyper sounds overly compressed, "toy-ish", and not as dynamic as the JMD. The JMD won Amp of the Year and Guitar Player's Editor pick for a reason. As long as you keep in mind its a hybrid and not compare it to top line tube amps, you'll be satisfied. I have / had numerous boutique tubes amps and still own a Fuchs ODS 50 and modded Carvin x100b. They feel and respond with pure tube tone and compression that the JMD can't match, but is really close on a few models. Sure you can compare this to an all tube amp in its price range and feel that it beats the JMD in tone and feel, but I can tell you from owning serveral boutique amps (i have a Fuchs ODS 50 and moddified Carvin X100 still) the JMD is a deal because I'm sure you'll find at least one model that will make you grin, and when you add all the effects / extras, it makes it worth the money. To me, all the cleans are great (keep the preamp level high, if not, it will sound thin) the Crunch tones are great, and the Classic OD and Deep Lead are really great sounding and with a nice tube-ish compression. If you do buy it, make sure you give it all the time that is allowed in your retailer's return policy. You really need to explore this amp. I'd also recommend a tube change. It has cheap Chinese tubes. I haven't changed mine yet, but will.
This amp is a nice amp, but for the price you can get much better. This amp sounds pretty digital, and the pre-amp is fairly fake sounding. Do yourself a favor and play a bogner or a mesa boogie express
When I heard that this amp models some of Marshall's greatest amps I thought it was going to be a sure failure. However I was wrong! Everything was crisp warm, real sounding and the modulation effects are sweet. I would definitely take it to gig with. 5 STARS!
When I plugged in my Les Paul the acoustics just stood out.
This amp is amazing. I loaded it up with my Zakk wylde overdrive pedal and the thing gave me a nice crunching tone that i have been looking for.
couldn't have been happier. only $40 a month financed, i play this amp every day and i must say that i am impressed. The pre-amp modules sound very convincing but being digital, do not give the rightful interaction with the power section despite being equipped with EL34s in this department. The plus point here is the amp's tonal clarity, it is indeed one of the manufacturer's best. I was skeptical before but having heard it in action, I praise it for its primary duty- the provision of good (Marshall) tones.
Marshall MUST be be tube. Understand that the pre-amp section here is absolutely digital. Tone is clear except being that jdm's are digital they do not give the rightful interaction with the power section despite being equipped with EL34s. Still a great amp!!!!
Awesome Product! I use one professionally at gigs. Never have trouble and first rate Marshall quality. It's a Marshall so expect true Marshall tone! The distortion is typical Marshall, the clean is Marshall clean. It doesn't have the Fender clean sparkle but is very acceptable. Not sure if would be good for country players as I'm into blues and hard rock.
