Hatsubai's review"Slash's signature Marshall"

Marshall 2555SL JCM Slash Signature
This amplifier is the amp that Marshall designed in conjunction with the famous Guns n Roses guitarist Slash. It was modeled after his other Marshall amplifiers he used, and I find it bears a lot of similarities to the JCM800. It is a single channel amplifier with four EL34 tubes and three 12AX7 tubes. Everything is fairly straight forward on it just like the old school JCM800s, but this amplifier has a footswitchable volume pot, an effects loop, a DI out and a low/high output switch.


The amp is extremely easy to dial in, and you can get tons of great tones immediately. The additional features that this amp has over the JCM800 makes it a bit more desirable, and there are some interesting things going in underneath. During the JCM900 years, Marshall started using diodes for clipping. These diodes were given a bad rap because the JCM900s didn't sound too great. However, people went gaga over this amp for its extra gain and awesome tone. In reality, this amp has diodes being used in the clipping section just like the JCM900 did. Amazing what a famous guitarist's name will do for an amplifier. Now, I'm not saying it's the same as the JCM900 because it's not. However, it does have some similarities at times.


The amp sounds great, and I find it sounds even better once you throw a boost in front of it. Once you do, it gets this awesome pissed off Marshall sound that absolutely roars. The footswitchable master volumes make it great for when you need to boost the volume for those lead boosts, but since it has an effects loop, you could always just throw an EQ or something in the loop to increase the volume. Therefore, the feature isn't quite necessary, in my opinion. I actually always used this on the high output setting, so I can't really commend on the lower output setting.


These amps can get pretty pricey thanks to their rarity and Slash's signature name. They sound great, and while they're kinda worth it, I find that there are better Marshalls out there today, especially thanks to the JVM and VM that recently came out. If you're a Slash fan, you'll probably want to look into the new AFD amplifier anyway.

Marshall 2555SL JCM Slash Signature
Power is less than 100 wa amplify the zenith is more than enough
The connectors are jack
Slash settings / rock, can midrange. Footswitch two positions
Presence of an effects loop. I have about 8 pedals in the loop

I did recently change lamps for 350 €.


Nothing more simple


Yes rock year 70/80, I play gibson custom.

Sound distortion at a good grain, clear sound is as clear as its name suggests.


I acquired pre-97, but I had to change the lights, see the prices today.

This is a product that will surely become collectable as can findable on the second hand market. Compared to afd it is much more versatile. Slash uses in its clear and distortion c is afd available.

Marshall 2555SL JCM Slash Signature
Tube guitar amplifier, 100 watts, 2CH, insert loop ...


Super easy to find the sounds! You turn the knobs and it Tarache head.


For me it is by far the best head Marshall on the market today (even if it is no longer marketed). The sound kills! net.Le is clear and its really clear and clear to clear, a clarity and clarity mad, the CRUCH us back into our good old classic rock and pushing the distortion that sent severe (without however, having one side made of metal or too compressed).
So for those who like the "real" its Marshall, who plays rock / blues / hard / jazz, this is a must to play fatter and fatter (like black metal and Company, a disto ptite more or go see at the side of Mesa).
It's a head without compromise and that's all bad!


For me it is the Holy Grail, you will find OCCAZ and do not pay too much either because it is not that easy to find. In addition if one day you sell it, do it in riquains, the low rates senvolent fast enough for this little jewelry.

Marshall 2555SL JCM Slash Signature
For the record, the 2550 is a jubilee anniversary model of the 80s (I think ...) and is considered one of the best marshall amp. 2 Slash owns one of which was pretty damaged during a riot at a concert of Guns N'Roses. So, Marshall has released a new edition of the jubilee limited to 3000 copies worldwide: JCM Slash.

Good in the characteristics is a super simple amp, it has not really need the doc ...
This is an all-tube amp two channels: a marshall in the state of the art!!

Ah is a hyper little thing important: this amp is handmade!! It's very upscale! The quality of manufacturing, component and assembly is truly impressive

Front: 3 buttons on the left, the power, the stand-by and a button that lets you toggle between 100Watt and 50Watt (attention be fo-stage by forthe do!) Basically it's been working 4 lamps or 2 lamps power! So it changes a lot the grain of the amp ...

In terms of the settings is very simple: gain, bass, mid, aspen presence, output gain, master.
2 knobs are push-pull: one to change channels and to change the grain and have a clear channel to the JCM800

At the back is classic: 2 HP, an effects loop, footswitch jack and voila!


Very easy to use but be careful so the settings are hyper efficient and therefore this type of amp EQ and super important and changes the sound completely.

Overall everything works perfectly and I love: there's no 50 buttons! is simple and effective. And above all fo understand that the sound palette is very wide! This is not the number of buttons that set the width of the sound palette!

the negative point that I would like to change: is there a single EQ for 2 channels! but hey it's like that with Marshall for years (except the last amps) so fo do with it.
And anyway with this amp you put yourself on boosted channel and if you want a clean sound you lower the volume of your guitar and you're done!
I put 9 because I can not regard it as a default: this amp is a reissue so they would not necessarily change everything ...


eh eh eh

how to express what I think: this is the sound of my dreams! it's as simple as that.
It's not the sound of a JCM900 or JCM2000 (and fortunately saw the shit ...) or a JCM800! it is a jubilee and the sound is unique, it's also the sound of Slash!

I'm in love with everything about this amp. the clean sound, the crunch and saturated. You can do anything with.
This is the perfect base!
you want a bigger sound: you add a tube screamer, a compressor and / or equalizer

Already the basic sound is huge and the most enjoyable thing is not to push the gain on the bottom but kind to 6 / 7 and you decrease the volume of the guitar. here you have a crunch / clear beautiful as the attack on the pick: I love it!

In general it is the sound marshall par excellence: very rich and malleable can be anything you want. When the amp is set to the sound palette is in the fingers !!!!!


It's been a little over a year since I have it. I was lucky to find one of OCCAZ and really it's great!
I tried a ton of head marshall before: JCM800, JCM 2000 and my choice was stopped on the JCM2000 DSL50 which to my taste was the one that sounded best!
But I came across an ad for a JCM Slash and frankly I do not regret one second my choice!

It is not easy to find OCCAZ and the price is around € 700 is very good! Of course if you get the jump on the original jubilee is extremely rare and it is the most sought after amp marshall!

if you want further advice here is the link to harmony central (in English) where a lot of people gave its opinion on it, and everyone agrees: this is certainly one of the best marshall! !

No need to tell you that I do it again this choice with eyes closed!
