Marshall JCM 800

Made by Marshall

Description I have had a 1984 Marshall JCM 800 for about three years, and it is the best amp I have ever owned. It is versatile and powerful. I couldn't ask for a better amplifier.

I love this amp. It sounds great, and does what you expect from rock amp. The only draw back (typical of tube amps) is that it is heavy. But the sound you get makes up for all of it!!!
Where Obtained: Guitar Center
Features:
It is a typical Marshall - Preamp, Master, Treble, Midrange, Bass, Presence. On/Off and Standby Switches
Sound Quality:
Just your great Marshall tones. What more can you say about this amp!!!???
Ease of Use:
No Programing - just dial and go! This is the way all amps should be made!!!
Durability:
Since I bought it used, it has road wear. The isn't ready to be retubed but like all Marshall's, they are built like tanks!!!

It gets no better than this.The sound is the thing.No amp sounds like a Marshall.You can't model it and get the real thing.The only way it could be better is that I would have 2 or 3 of them...
Price: $300.00
Where Obtained: friend
Features:
Master volume,presence control and a standby switch.It has a high and low channel,but doesn't channel switch.Mine's a 50 watt head that is LOUD!!And crunch galore.Tubes all the way.
Sound Quality:
My main guitars I use are a 1974 Gibson Les Paul w/Bill Lawrence L-500 PICKUPS,2002 Fender USA Strat w/EMG DG-20 pickup assembly.Awesome set up,for sure.The JCM-800 SCREAMS.A great rock or metal amp.A tad noisy at times.The low channel is clean and bites.The high channel is pure Marshall.
Ease of Use:
Plug in and go.No programming crap here
Durability:
I've had it over 15 years without a problem.Buy one,it's road durable.

Like I said no amp does it all but this one has gotten the closest for my needs. The best thing is NO BELLS OR WHISLES!!! The marshalls with all the fancy crap on them sound like s---! Jim Marshalls original rigs didn't have that crap and they sound the best! Just Plug your axe in and start thundering!!!
Price: $400.00
Where Obtained: danny music bos El Paso Tx
Features:
Basic amp no bells or whistles but it is master volume More than powerful enough, way louder than my cousin's jcm900 I can fully drown him! All tube Baby all the way to the hilt!
Sound Quality:
I have 15 Different electrics I plug into it they all sound different. Sounds Good for everything from blues to metal, thought about switching amps but the guys in my band said "NO Way Dude!!!" The best amps (I use two) I've ever had but still haven't found "the Dream Amp" one that gets everything! This one comes the closest.
Ease of Use:
Easy to use I have an old Gsp-21 Legend I use for minimal effects. Simple set up and it Thunders Big time!!! Only 50 watts per head, but something must be wrong cause it's WAY louder than any 100 watter I've tried.
Durability:
Very reliable, fell off the top of a full stack and still workes, no gliches!! Man you shoulda seen how nervous I was to plug that thing in and see if it still lit tubes!!!

I'm a Marshall amp collector, so I didn't look at other options.

The only thing Marshall left out of these early model amps was a reverb tank.

The tone and pre-amp feature are my favorite aspects of the amp. Can't think of any problems with it.

I recommend this amp over any Marshall on the market right now, because it is very basic, with no frills to tangle with, or have go bad on you.
Model Year: 1982
Price: $550.00
Where Obtained: ebay
Features:
Probably the best Marshall amp that came out in the 80's and it is still a sought after tone Dawg !! It's rating of 50 watts rms, seems like 400 watts. Turn it up past 4 and I can't take it. It's a tube amp and is quite basic, with no frills except the pre-amp control which allows distortion at low volume. The only other control besides the usual ones, is a Presence control which adds even more of that great Marshall tone.
Sound Quality:
I use a Gibson Les Paul Standard through it, which makes it that much sweeter. Plus I run it through a JCM 900 Lead 4X12 slant cab. I also have the matching bottom cabinet (for a full stack), but I haven't tried stacking them yet. I'm sure the house would blow up if I stacked them up and cranked it. I use chorus at low levels, almost all the time. And occasionally a Dunlop Cry Baby wah. For recording I will hook up a POD, and run it through the amp, then back into the pc. This really enhances the POD capabilities. I play mainly Rock/Metal but have been getting into the Blues lately.
Ease of Use:
It has very few controls, so it is too easy to use !!
Durability:
Well, it's a Marshall, what else can I say but yes, it is very durable, and the construction is heavy duty. It's just been re-tubed, and I biased it with my biasing meter (BTW, a very handy tool), so I won't be concerned with re-tubing for at least a year or more.

I heard this amp, and decided I needed to have it. Its sound is that good. I would buy this amp again if I had too.

The JCM 800 could be better with a reverb unit, or another channel.

The best aspect about it is its superior sound. On the bad side it is rather heavy.
Model Year: 1984
Price: $450.00
Where Obtained: Friend
Features:
The JCM 800 has six controls; preamp volume, master volume, bass, middle, treble and presence. It has one channel and no effects loop. It is a tube amp, and is mono. It is incredibly powerful. This is a 50 Watt amp, and I cannot turn the volume past halfway- it is too loud at that point.
Sound Quality:
I use this amp with an Epiphone strat-style guitar. I have also used a jazzmaster with the amp. It works well with chorus units, flangers and phasers. It is extremely well suited for rock. It has a smooth distortion sound that is wonderful. Its clean sound is also very smooth. It is by far the best amp I've ever used. I would say it is at least as good as a Fender Twin. The JCM 800 isn't noisy, and can stay clean at high volumes. It has great distortion as well, but not if you're looking for heavy metal, compressed tones. This has more of a seventies, rock and roll sound.
Ease of Use:
The amp is very easy to use. I recommend dipping the treble and boosting the mid range. That mutes some of those high pitched "squawking" noises you get when playing at a high volume. With only six knobs, it doesn't take much time to get a good sound.
Durability:
The amp is very durable and is made of solid material. I haven't played any newer Marshalls, but they made these ones to last. I have never had it re tubed, but I do not play it on a regular basis (I do not play live or travel with it).
