To start off these things are LOUD. If your looking to recreate the "golden" days of Marshall tone look no further. The simplicity of these amps are what makes them so great. This IS the tone of 60's and 70's rock music and they are capable of ear destroying, hair staightening volume. The amp sounds awesome when warmed up with a good OD or distortion pedal and is much more useable with the use of pedals since they are very loud when cranked to levels that induce that classic Marshall distortion.The amp is very neatly built with good quality components (not much plastic) that should last for many, many years. While some may complain about the lack of master volume and all the other bells and whistles of other models or manufacturers it is an awesome tone machine for sure. So if your looking for that old school tone look no further. Did I mention this think is very loud?

This amp was a big disappointment. Doesn't sound anything like original plexi's, mostly because they are wired and made very differently. This was supposed to sound like EVH or Page etc...which is funny because it sounds flabby, weak, and brittle sounding when pushed to 10. It never evens out nicely. On channel 1 it's too thin, and on channel 2 it's too muddy. Jumping the channels help but I just wasn't getting a good tone. Your paying for the name on this one. Which is too bad because the actual value of this amp on the street is a lot less. Marshall really sunk low this time using ultra cheap parts, tubes, and poor biasing. Save your money and get a vintage one.

Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

I DARE you to find a better tone......seriously. I have bought and sold and tried tons of amps and gear, trying to beat this amp and I cant. It has the fattest cleans I think are possible, which is what I go for. Pedals do the rest.

If you want a crunch machine this is not it. Please understand, a single channel basic tube amp crunching is the amp "failing", the tubes are being over powered by your guitar signal. With today's PA's you dont need an amp with this kind of power if you want natural tube distortion. What you do need is clean headroom and huge muscular tone on which to build your sound, and this amp delivers that better than anybody.

Every other amp out there is a joke to me, including boutique stuff. The only thing that is AS good is just another company's copy of this amp essentially. And guess what? You aint gonna sound like Jimi Hendrix or Pete Townshend or Clapton or Page....you'll sound like YOU. And thats a gift. Why are pieces of equipment like this around for so long? Because its a real tool to make music with, just like a strat or a les paul. They let YOUR sound come out. Amen!

I have two 1959SLPX heads. If you really want to raise the roof, this is it. Total reliability, consistant tone, and the power of Thor. Some guys don't dig it because they think it's too loud. Well, I say if it's too loud, you're too old. Use this head. If you can play, they'll remember you!

    Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

    My main amp is a Marshall JMP 2203 with a master volume. I love this amp and got the bug to get a non master volume Marshall. My intention was to get the classic Marshall crunch with 100% natural tube overdrive like they used to.....crank it up! Well folks I'm here to tell ya, for as much info is out there concerning the the 1959slp, the shear volume is WAY understated. WAY! This is not a complaint, but definitely a concern. First, let's talk sounds.......

    I use Les Pauls with stock humbuckers and a 1960ax cab. The first sounds I got from the 1959 were clean tones. Giant, lush, shimmery strummed chords with wonderful overtones, and ultra defined picking patterns with glassy punch. It's bold and beautiful and could work for anything from Reggae to Jazz to Country. Does this sound like a Les Paul into a Marshall halfstack? Believe it.

    Turning up the volume, I start to get some dirt. This is a great point on the amp because the way you attack your strings dictates your sound. You don't need to use your guitar volume yet to jump between nice cleans or gritty grit, and she'll start to bark a little when banging out some chords. I'd also like to add that I do 'jump' the channels on the amp. I feel that it gives me more tonal control than using the EQ alone. The fullness of channel 2 and the top end of channel 1 blend nicely.

    Now for the sound I'm really after, full on crunchola! To be honest, my excitement waned as my initial attempts at this failed. To push the power tubes into overdrive, you have to turn up the volume until those babies start to cook. Well before I can truly get there, the decibel level is already melting faces.....mine, my dog's, the neighbor's kid playing outside. I was bummed because I didn't wanna use any external devices like attenuators or overdrive pedals to achieve what the amp is already capable of doing. Not to mention the fact that there isn't a single club in town that would allow such madness to take place. In the end, I did buy both a Marshall Powerbreak and a Fulltone Full Drive 2. The powerbreak actually sounds rather good when run almost wide open. I'm also not diming my amp's volume, as I'm getting great saturation at @ 6 on both channels. It would be foolish to think the powerbreak isn't coloring the sound in some way but I must say that albeit loud as hell, it sounds great! The fulltone is another review by itself, but the amp responds beautifully with an overdrive pedal. Admittedly, the full drive 2 has made the SLP a more 'usable' amp in the sense that I can get clean, grit, cruch, and lead, all with 1 setting on both.

    As a stand alone amp, it will impress. The range of sounds are all there. The only bit of advice will be to consider what purpose it will serve for you. For myself, I wanted this amp for it's overdrive without using outboard devices. Being a local guitarist, playing venues for locals, it's not gonna happen. Nevertheless, I do love this amp and would recommend it for anyone who can make sense of my brief review.

    Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

    I have owned alot (and I mean alot) of Marshalls. From my 1st one which was an original 1966/67 JTM45 (that my very supportive Mom purchase new for me in 1967) to this 2004 1959 plexi. I love this amp!!!!! I use it with the channels patched together, installed JJ's and rebiased it a tad hotter. I usually run it with the volume around 30% and run several overdrives/distortion pedals for gain (favorites being the Fulltone Fulldrive and MI Crunchbox). I use the effects loop for a Realtube rackmount reverb (rare and out of production). This amp has never failed me, can be unearthly loud, and sitting on its 4x12 cabinet just makes me feel younger (I am 55, that's 7.85 in dog years) I'm very much a "child of Beano", Cream, Jeff Beck, James Page etc., and I am one of those who believes "Clapton is God". No they don't sound just like my old ones...no better or worse...just different with it's own unique plexi voice. Jim Marshall made it possible for me to do what I do for a living...may Eric Clapton errr....Uhhh... I mean God Bless Him.

      from Undisclosed

      Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

      I've owned this head for about a year and a half now, bought it brand new. I've learned so much about these amps. They take some special care dialing it in, for example I removed the bright capacitor and now it sounds great. You have to use high quality tubes, this amp is very responsive to changes in tubes. The better you use the better it sounds. Use good speakers! I prefer the vintage 30's, or g12h30s. Other than that she's been a real work horse and provides the power you need to get that soaring guitar solo. Realize this is not the amp for every venue but you'll be glad you bought it if you do. Mine will certainly not be parting ways with me for a very long time. I've played a good number of vintage plexis as well as boutique high end copies and I really think once you get the right speakers and tubes, they're all really close.

      Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

      This amp is loud. It is so loud it makes my teeth hurt. Takes a little time to dial in the sound(I jump the channels together) but it really sounds pretty good. I have a 94' without the loop so I can't comment on the loop function/sound degradation. I really don't know where you guys are playing that will allow you to turn this up to it's sweet spot, but it really does have a great Rock tone. Takes screamers well, classic combo. I would get an attentuator to play live, or prepare for your soundman turning your cabinet into the back wall.

      1959 slp plexi ri

      Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

      I have owned JCM 800 1959, 1987, Fender Twins, crates, peavey 5150 ect..IMO Marshall they did something right with this amp. It will give you the classic rock tone of Page, Hendrix. The difference between the jcm 800 imo is they sound better metal or modern rock where the the plexi ri is classic rock. I can use a pedal to go metal. The kiss method serves me best, all I need is a clean amp that can be overdriven and I can use a pedal for more mdern metal. I started to by a vintage marshall plexi and chose the re- issue because of reliabilty issues, I know it does not have the mojo and needs to be broken in but I also know the vintage oldies all need some tlc dio to there age and abuse over the years. Accept no substitute there can be only one MARSHALL has Rocked the world for over 40 years+ all the other are just trying to sound like them.

      This Amp has that amazing Vintage Plexi tone! no matter what other people say about how the reissues dont sound as good as the old ones its not true I studied and played every plexi I could get my hand's from 67 and on and the only difference is price and the new ones are a little bit brighter which only makes it better for recording. If you can actualy play the guitar and you want classic tone that this is the amp for you.

      Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

      As an owner of "VINTAGE" Super Lead Plexi's, I dont know, (or care), where all you "would be" experts are getting the hype-fish-hooks sunk into your faces, because in the last 27 years, vintage Marshalls have been just/as, if not MORE TEMPRAMENTAL than ANY re-issue. 98% of you couldnt tell the difference at stage volume TO BE SURE! The re-issue is dependable, Loud, and has 10 times more tone value than any of the 800, 900, or 2000 series. Go ahead, make 1000 mods to it, complain about it's simplicity, ect. I for one find the newer ones MORE RELIABLE! This is the HIGHEST priced amp head Marshall makes, (and not because it's retro!) These amp heads are on MORE big stages than ANY other! DO YOUR HOMEWORK before shooting off your mouth!

          Anything from jazz to classic rock, this thing is an incredible tone machine:use the dark channel for jazz.use a jumper for full-bodied sound.use the high channel for classic ACDC sound (crank out the amp).use an a/b box & then you have two channels.boost it with a little bit of overdrive and crank out the amp and sound like yngwie malmsteen.

          Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

          having owned about 75 100 &50 watt marshall heads over the past 35 years ,i think marshall did a pretty good job recreating the real thing for aa reasonable price.the lastest one im useing is from 1995 and is real good smooth bitey not thin or brittle,they do vary.a 50 watt version[1987]was the opposite,not very good at all [all treble]i have a dsl 100 and it does a fair job of mimicking the plexi but it is still not the same.the reissue is definately more relible than the 1960s version they were as another reviewer stated very temperamental and many musicians in the 70s would be leary of useing them instead useing the metal panel models being produced at the time [69-76]back them all my plexis blew up on a regular basis....the new does not have those problem issues.

          Comments about Marshall Plexi 1959SLP 100W Tube Guitar Amp Head:

          Ok, The SPLX is most definately not an amp for first timers. You will not get the most out of this amp if you do not have the basic understanding of tubes, biasing, and speakers. I recommend looking up an original, you'll save a few hundred, though if you're into looping then buy this. Absolutely buy a powerbrake, it will sound better cranked, and invest in tubes because you will wear them out sooner when cranking it. Play with different power tubes *note* YOU WILL NEED TO REBIAS THE AMP, if you lack the skill or knowledge then take it to a tech, be safe.Try it with greenbacks or vintage30s. If you halfstack this with greenbacks use a powerbrake (I learned the hard way haha). This amp CAN do anything you want it to if you know what you're doing. Stock or rodded, this is where it really starts. If you want out of the box versatility with nice tone then go with a JCM2000 DSL, TSL, or a Carvin MTS head. Happy jamming.

          If you're striving to get those classic tones and you're tired of the modeling amps and all the other hybrid amps that claim they will give you the sound you so desperately seek but just don't deliver, your search is over. This is the amp that originally created those classic tones, so why not just step up to the plate and buy one. You'll never be happier with your decision. From Classic Zepplin, Cream, Aerosmith, The Who, Deep Purple (Just to name a very few) This is the amp that was used way back then and still creates that awesome Rock tone some of us have been looking for all of our lives. Sure it's a LOUD Beast but it can be easily controlled with a power attenuator. Just get one or try one out. You'll be glad you did and I have to say honestly, this is the 12th Marshall I have owned and I simply Love and Adore it. He he he! My 50 watt 1987x Kicks some major butt too!

          this is the real deal! this thing shakes the walls in my house, it makes my dog vomit and crushes anything in its way. I really love my slp, I have had some getting use to it though. It is just too darn loud at times. It's 100w but pure marshall watts. this thing is louder than anything that I have ever played before. I play it through a 1960 4x12, and get a sweet tone. I bought a volume pedal for it, to get multiple tones and I am thinking of getting a power brake to lessen the volume. If volume is what you want, this is the holy grail.
