Marshall Vintage Reissues Sound Exactly Like the Original!

Though the 50-watt Marshall 1987XL shares the same front and rear panel features as its big brother, the 1959 SLP, it does have its own distinct personality. Sweet warm singing sounds are packed into every nook and cranny of this great tone machine.

Marshall 1987XL Features:
  • Part of the Marshall Vintage Series
  • Mix two channels together for a totally unique sound
  • New series effects loop feature
  • Vintage Marshall through and through

Part of the Marshall Vintage Series
The main characteristic that these amps share is their simplicity of operation and superb natural valve tone. Achieving the beautifully organic and vibrant overdrive which is their trademark, and can only be done in one way - crank 'em up! The result is pure, majestic tone uncluttered by unnecessary circuitry. This produces a big, round, warm, sustain, full of classic character. With chord work you get a bark and percussive attack with a natural sounding breakup, which allows each note to ring out in a glorious musical crunch.

Mix two channels together for a totally unique sound
With the Marshall 1987XL, you can mix the two channels together by connecting a short, screened patch lead between the second input of channel one and the first input of channel two. If you then plug your guitar into the first input of channel one, you can mix the different tonal characters of each channel for greater flexibility!

New series effects loop feature
The series effects loop features a true bypass switch that takes the loop completely out of the circuit, thus ensuring that the original tone isn't compromised. The level switch allows you match the loop to either stompboxes or rack units.

Vintage Marshall through and through
As is the case with the 1959SLP, the 1987X has fittings and hardware as true to the originals as humanly possible, thus ensuring that authentic Marshall Vintage look.

Marshall 1987XL Features:
  • 50-watt output
  • Preamp Valves: 3 x ECC83 preamp tubes and 2 x EL34 power amp tubes
  • 3-band EQ
  • Presence control
A faithful reproduction of the original, the Marshall 1987XL is just what you're looking for!

Simply vintage

After being played many great amps for the last 20 years I became very choosy and spoiled. At first I decided to sell it but luckily no one bought it until I understood what a mistake it was. This amp can not do the high gain modern stuff, it is frustrating to see that you need pedals in front to push it for that but when you push it does a very unique throaty and vintage type hi gain that no other amp can do. However it nails every other amp in crunch. Just max the two channels, gang them and you'd get in heaven. For clean stuff it is indispensable for country style or any type of clean sound that cuts through any dense mix without a touch of eq. The eq controls are totally useless because they seem like boosting or cutting a few dbs even at maximums but I tell you, no need for them, the amp itself sounds very unique. Another important thing is, this amp sounds dull with v30s, you need to put it through a g12h75 30 watt, then you will know what I'm talking about. I deleted the add I put for selling it after actually changing the speaker. I also highly recommend a hi output pickup since classic seymour duncan 59s are just the worst choice for this amp (dimarzio's super dist pups made me a happy man!).

Marshall 1987x

I have owned many different Marshall amps over the years some to loud and can't play many places and some just not loud enough to get the tone I'm looking for but the Marshall 1987x is the way to go for me. This amp is still very loud and it takes a few days to dial it in but this baby has got the British bite of its big brother the 1959 super lead for sure ( I have one of them to) This amp is loud at 1 to 3 then it just gets dirty dirty I like it. But that is still the perfect sound for me at studio level and most gigs with out a PA on my cabs. This amp does not have any head room it's all gain if you want a little clean you'll have to roll the old volume knobs down on your Paul's. I have not modded this and never will it's perfect some people change the Brite cap to give more head room and more clean at lower volume but why do that just get a different and because this amp was made to grind rite out of the box

Best amp on the market.

I bought this amp about a month ago, it has always been my dream amp and I finally ordered one after all the years of debate. At first I was nervous because I've played Orange amps all my life and honestly didn't think anything could stack up to the AD30. I couldn't have been more wrong, this amp is amazing! Very versatile, great for blues, classic rock, jazz and even country. The only thing I would say is that this amp is EXTREMELY LOUD!!!! & by that I mean knock the walls down, blow your ear drums out type loud. An attenuator is a must for this amp unless you live alone and your nearest neighbor is a good distance away. Other then that it's perfect... we play mostly originals but do cover some Led Zeppelin, Eric Clapton, Fleetwood Mac, etc,etc. & this amp covers all those signature tones perfectly. Especially that of Jimmy Page. If you're in the market for a beautiful tube amp, this is ( in my opinion) the only way to go. I give this amp a 20 outta 10.

If your looking for that classic crunch this is it!

Great amp! Sounds good no matter what you have the settings on! However it is very very loud, and there is only one way to run it which is cranked. I'm sure if you are looking into purchasing one you know that already, this is not a bedroom amp! I would highly recommend a good attenuator to tame this beast. Overall this is a killer amp for blues/classic rock if that's what you're looking for. This thing rocks, super articulate, clear and the distortion is just creamy goodness!! The 4 inputs are great as you can easily find a tone that suits you with bridging the different inputs and what not. It also has an fx loop which is a great feature as original plexi's did not have this feature but it is not intrusive at all. I've been running it with a noise supressor/wah/bbe green screamer if i just need a little more gain and i also use and eq pedal for a nice cleans boost and this thing just sings. It is very natural sounding and not overly processed like most amps today. I switched out the preamp tubes to some NOS Rca 12ax7a's and those made it even more creamy and a little less bright which i think made this thing just about perfect. If your looking for that classic crunch and the sound that made rock this is it, you won't be dissappointed!!!

Great Vintage Tone

Everything you would expect from a legendary amp. It really comes alive when channel 1 & 2 are bridged together. The channels separately are not great unless bass & treble is adjusted in front of the amp with effects. Amp came came classic Winged C el34 tubes...unbelievable bass & really bright treble. Tubes were biased a little hot. Overall great vintage tone & sustain during breakup...Luv the Plexi 50 watt!
