NOTICE GLOBAL

I, unwanted for 2 ans.Avant I Fender, the twin red knob.

100w amp head two channels. 4 EQ bands common to both channels. Independent reverb settings. loop switch effect pentode, triode or 50 / 100w. a little less headroom and harmonic 50. 3 12AX7 pre-amp and 4 EL34 power 2 for me as it was in Retube 50w .. SEE my opinion on JCM900 Dual Reverb 4100 (yes it is listed two Once the head ...)

I did Retube in 50w. Mine is equipped with EL34 and not 5881 (I think this is a very important detail.), Model lamp more représentaif sound marshall.

My lights are Mullard EL34 with a 12AX7 input golden dragon. (A must for the clear.) The powers are no longer as the number 2 course, 50w forces, so it's switchable 50 / 25W.



USE

I precisely this point in detail "sounds".

It is not so obvious as it seems ....

SOUNDS

The whole problem. its use does not ultimately proves to be so easy because it asked to be pampered Marshall future.

This is a maligned amp. For me, the views of a minority opinions "international", see eg Harmony Central.

This is an amp that ultimately needs to be tamed. The one does not ring on. Its major problem is its lack of bass. Its equalization which seems inneficace but gentlemen: Let's stay serious when he spits his bowels, CA has absolutely nothing to do.
And until now, I said loud and clear:
No amp seduces me as much as that one. I saw the green and not ripe for 10 years now ...

A highlight is the mode of operation of the lamps. In pentode or triode if I'm not mistaken. Or 50 / 25W.

25 it will tend to be more "soft" more chubby than 50 or it will sometimes be more acidic and sharp.

My opinion is especially the 25w mode.
The Channel A:

His clear and overdrive. Jmp sound can easily get out of this thing to be done: a small das GE7 the loop. A low one is there.
At higher volumes it will touch équalo the amp itself, las low wake, acute too! My setting is a low background and a support adapted to each situation by GE7. The mids and treble thoroughly virtually cut off. I play with the presence that makes the finest eq setting.

For the top, this is my solo trip, AC / DC and others just to rant a little amp.
For purely sounds clear I am quite a fan of the compressor mixture / chorus, which gives all its density. I use an old compressor Guyatone ps103 (mod germanium) cruised to a Boss DC2. (Never heard of such a chorus: MAGISTRAL).

Channel B:
Clearly lead! for the pun ... CLAIR lead-ing ... Ok I spell ....

It spits fire god! High gain, it certainly is not, but remember that we are coming out of a period or to saturate the amp that was all thoroughly developed bar ... and may be not necessarily the way to a pedal od significantly less accessible today.
Today, with modern music, the high gain mention seems ridiculous ...

The grain has narrowed, compact, mute already very nice .. Iron maiden, metallica and justice for all ... In her I always use my GE7, but in addition I stick him overdrive on the teeth!
A sd1 or Od1 home boss, that's what makes it sound better, mediums forward and dry acute, are perfectly acitivities grain of the amp.
Mutes are so daunting! mdrr!

One enters the Deftones without worry. It's heavy, dense and thick has wish. Muscle Marshall in all its glory, every time in 3 years I remain stuck and I'm in love! It amazes me to this amp AC, he knows how to clean, hard, heavy metal and carefree.

The reverb filled his role well, I find it a bit long, fine adjustments to the beginning of beach ca not displease me ...

In short, a versatile amp with a vintage anyway its always on the settings of channel A, and well suited to rock / hard / heavy.


NOTICE GLOBAL

If it were to do again, (I got it for 400 euros) I remade on.

In short it is an amp you need to know and do to tame what he's done. Versatile, and also inexpensive opportunity. For a review and a max!
Some settings and for me (it's also a pleasure to be HIS type of sound) in 25w rather, good lights, good effects and good guitarist.

Finally I ca work! mdrrr

All t said.
the loop is very useful (not work very well as on many amp made in china!)
switch hi / low super efficient
power tubes el 34 or 5881 (6L6) as model (I have a 6L6 and EL34, so I speak both)

USE

Super easy to use, sounds are easily exploitable, just make sure the master volume aprivoiser very reactive but even low volume was sound.

SONORITS

I play hard rock and metal (70's / 80's / modern thrash genre) and unlike what some say, YES c'st possible to have a big fucking her saturates !!! Just:
1: whether the lamps are not dead or otherwise not bother to post a comment !!!
2: have good hp (personally a fact largely the case in 1936)
3: having a good scratch (for me vigier exca Di Marzio tone zone, bam pro and also with super distortion affects mapleneck / sg std / les paul std Burstbucker alnico / jackson Seymour Duncan tb4 rosewood / Charvel San Dimas ditto plus 59 handle Maple and touches everything in standard tuning either re re diese diese either with low E string pulling drope 10/46)
4: Learn to play !!! and have something to compare! (I have not bought amp poorly lamps)
For me JCM900 synonymous with precision and feeling, nothing to do with the JCM2000 and jvm, this amp is the last true that sounds like marshall marshall!
Remember that it has created and to counter the Soldano and other mesa fashion in the 90's and the permetre schreders and metaleux to stay at marshall.

Here are the sounds /
clean very good for a marshall (useful for connecting a distortion)
clean with good gain for blues, AC / DC, Led Zeppelin
od very classic rock
od with max gain good for hard rock
od tube screamer with a view equalizer and it's perfect for thrash metal (precision with harmonic = hell solo)
with serious tuning and good mics = palm mute clear and punchy; cavalcades thrash (Metallica, Megadeth ...)
The reverb is pretty cool
The equalization may seem innefficace but I find that c an advantage is not going 2:00 settle its mids for example; here it sounds now.

el 34 or 6L6?
I will say that the 6L6 are more roots than the EL34 without losing the precision with more harmonics (very hendrix crunch)
El 34 drive bottom episodes with tube screamer are more modern with a thicker grain (personal opinion) stridant least as in the treble.

Hi Mode or low?

As low sound is softer fatter less precise because less powerful (50W)
Hi are over sin and shine but it less manageable small volume, must push for a ring!

NOTICE GLOBAL

I recommend this amp to anyone who row to find a good sound with the recent stuff often too expensive, too cold; complicated and not reliable enough; if not love good grain marshall c c'st not for you !!!

Amp originally fitted with 4 x 5881, I did change to support 4 x EL34 "Mulard".
Amp 100W, 50W in swtichable (triode: loses power but also the characteristic)
2 foot switchable channels.
Channel A: clean -> crunch
Channel B: crunch -> overdrive
Loop insertion effect balance with -10 / +4 dB

UTILIZATION

2 amps easy to use switchable channels

SOUNDS

Suitable for Blues, Rock and even Metal.

OVERALL OPINION

Used since 1998
What I like: Channel A cranked overdrive with a good front.
I also like: changes made to the channel B (diode bridge split) which gives a closer rendering JCM 800 punch.

100 watt head lamps .... The settings on this head are not at the forefront .... not much opportunity since SETTINGS pots do not respond on a large beach .... but we can solve this small lacunne by purchasing a pedal of equalization (boss ge-7 for me) and you realize that some things holds big!!

UTILIZATION

For my part, the configuration is quite complicated .... I have two speakers who will lead in 1960 with A + B. ... connectivity is quite complicated, I had to look on this site for the information necessary .... but with good advice I got I am absolutely very happy!! I did not get a manual with but at the price I paid I even had the 1960 A cabinet with!! sound of the amp is very good if you look for rock sounds .... but we must add effects to get the big sound ... its very hot and the distortion is effective wish a very good clean and also easy to find!

SOUNDS

I like metalheads and rockeux .... this is the amp of choice for my type of player .... I use a digital delay, a chorus and a set of preamp eq ... j ' addition follows a ibanez tube screamer overdrive for Narrow my sound and have the teeth to the metal ... the sound is really good ... in 25 years it is my hobby and best sound is the sound I was looking for! !

OVERALL OPINION

it's been 5 months that I use and I'm very satisfied ... nothing to do with the small combo amp and other fine good cheap!! that I like the most is that it is big, yes, but the sound is diffuse Surprisingly ... with 8x12 inches behind the ca pouuse and spreads halucinante way!!, as I bought it used, I can not I really pronounced on the value for money but in my opinion worth it ca pay dearly for this type of amp .... moin has to have a changing temperament, he will follow me all my life I think so! !

I brought this unit about 6 years ago and have still got it .Being an in experience guitarist at the time I chose the unit because of its name and reputation. I havent regret it, except for maybe a few short falls. I paid $1100 Australian dollars for it.

I like the distortion voice on this amp with its ability to give you a modern tube amp sound.
I also like its ability to give you 2 choices a clean and distortion sound at the stomp of a switch.

The thing that i dislike about the unit is the clean sound which tends to sound a bit "tinny" on its own. However, in saying this the clean sound can be beefed up by adding different effects with it i.e a tube screamer.

During relatively loud volumes my amp has a rattle or buzzing sound and im buggered if i can find out where it is comming from. I took it to an Marshall amp specialist and even he couldnt find where the rattle is coming from. The rattle can be only heard when Im close to the amp, and hence, it hardly bothers me.

My Marshall has been good to me and has never broken down after 6 years of in and out of boots, tipping over, kicking and dropping once from 1 metre. It has a distortion sound with balls and a clean sound with none which can be overcome with effects. If your thinking about buying one test the amp to make sure it doesnt rattle at a good volume.

All lamp
100 w to 300w head and 4x12 cabinet for celestion.
Between a jack (input), and between effects return, and direct recording output and finally jack pdalier rverb and distortion.
I well liked one second between two guitars to play the day of beef!

UTILIZATION

A simple config, except for those who do not know much about the 4, 8 or 16 ohms. The choice is nevertheless important for trs connection of the head to the cabinet. Stereo, mono, short ohms you get lost a little beginners and the more you risk altrer svrement sound, not to mention the stuff that can abmer .
The right sound? it's hard to talk about that gots both guitarists are Different. But for my part, I've never reaches the sound I'm looking for for years, but it is I who should be too demanding.
When purchasing the amp in the store, no manual I t provided by the receipt against yes!

SOUNDS

Not suitable for my type of music today. I am a rhythm guitarist with soul. on the other hand if you rock, or any other music mtal o you need the big sound ... this is for you!

I play a Stratocaster and a Gibson Les Paul. No need to tell you that Gibson + = JCM TNT (boom) attention ears. Finally if your angry with your neighbor, go ahead!

His fat, crunch, big sound. This amp sounds like a lanc drangster full speed. Difficult to mount the volume + 4. APRS good, you and your major vaccine ... If you like adventure ...

I shuffled the nanmoins gibson crunch and its pretty clear but the amp bluesy solo. the Rhythmic sharp and clear with this monster is a bit like driving a 38 ton 120 km / h on smaller roads Corsica ... not what.

OVERALL OPINION

I bought this amp in 95 or 96.
I dtest weight and size, f that in j'roule Nissan micra.
For love against his mouth, his look is fabulous and crazy people who like beautiful things.
My Previous amp silent is a Fender Champ 25
Too expensive to buy today, but is not the legends of rock? In terms of the quality of fabication is the hand-stitched. Trs is well finished, solid and Designed for exceptional Manir. It is a work of art.

If I had to repeat the purchase, I do not think that I run once more in the freelance beauty and big amp that everyone rve have. I rflchirais more about the style of music I play and the sound I expected.

MARSHALL JCM900 4100 100W head + cabinet 1960A
I have owned this Marchall for 2 / 3 years since I revndu recently. It cost me nine-9600F (€ 1450) (if I remember correctly) head + cabinet.

The head is equipped with four Sovtek 5881 (model military 6L6GC) for a power of 100W and 3 ECC83 Marshall brand. There is only one EQ (It is a shame): Bass, mid, treble and presence.
Gain, volume and reverb level for each channel (that's good). There are two channels (light / full). The channel change is accessed by a push on the head or via a footswitch (supplied with the unit) which controls also the setting off / on the reverb (that's good too).
The effects loop with adjustable level is good. Output preamp out can use the preamp output signal power on another section. As against the release compensed Record is supposed to be a simulation output with HP, is not widely used mainly saturated (its very sharp without dynamics (transistor type): no!).
There are two speaker outputs for connecting two cabinets with selection of the output impedance.

UTILIZATION

It is easy to use in general, there is the impedance switch which is not very clear (values ​​in brackets?)
One 2-channel EQ is not great, you have to make compromises ...
Nothing special to report ...

SOUNDS

In his clear, the sound is round, warm enough with a lot of medium (as is everything marshall), and is clean enough to ford same volume (if one does not grow too much gain). But it's still even less than a nickel Fender Twin amp. It's like RED HOT fairly powerful. If you push the gain on that channel are obtained Crunch sounds good. Too bad the EQ is not more efficient (but again it's a habit marshall). The spring reverb (Accutronics) blends well with the sound (if you stay sober with the level) and gives a prodondeur little.
Boosted channel gives sounds of rock blues to Hendrix (with the gain in the first half) to Rage against the machine (with the gain at the bottom) through AC / DC. It's not saturate very very strong and very medium, low and no bcp potato. Especially as the EQ is not more effective than the channel clear. If you like this kind of sound is the amp for you if ... check out the competition. This channel has a very distinctive sound. If you play metal, hardcore, or death, c not an amp for you! even for the progressive metal limit c! unless you add a distortion pedal for.
Even at high volume, blah!

OVERALL OPINION

I used this amp 2 / 3 years. I sold and I do not want to marshall equipment.
When I think they call the head JCM900 HI GAIN.
THIS IS NOT THE HI GAIN! just listen to a peavey 5150 (and many others) to understand. I find that even Valvestate saturate more!

I definitely would not recommend this head (except for the lovers of the marshall).
on the other hand, there are ways to find the cheap to OCCAZ.

I will always remember the very first time I test this amp !!!!! the day before, I had tried all day long a Soldano SLO 100 head in 1990. The next day I find myself with the JCM 900 hands: I immediately thought that the amp had one or two lamps qt ... and no, it sounds like a natural at: its a pretty feeble inintressant, I then open to see a little piti cabling I advise you not to do !!!!!! otherwise, you will ask this question every day at JCM 900: will you walk aujourdh'ui? There that one time, with any background (hello !!!!) neighbors and connecting an old strat L SERIES I had a pretty cool one: something the Malmsteem.

UTILIZATION

Super simple: you plug in the socket and the t'allumes Bourrier praying that he wants to work well

SOUNDS

Go your way: check out the c JCM 800 or buy you a "Cornford" English brand that kills in his marshall CATEGORY

OVERALL OPINION

Aie aie aie ....

I might be a desire to spare EQ 2 channels ... otherwise the rest is classic (and relatively complete)

UTILIZATION

The use is bone simple, any guitarist capable of holding three agreements need not open the manual!

SOUNDS

The party is the most controversial ...
Personally I have used for years with a Les Paul Studio is jousting without effect supplmentaire and I've never had a complain. However it is true that the sound palette is very tense and his "Marshall" is rather (too) easily recognizable ...
I think it's a very good choice for all that rock a little pchu ... For the music more "soft" options may be a little too thin for what is harder, the channel distortion is, in my opinion, not enough fat and Dfine.
But what is the alternative, punk rock, etc ... it is really very good!

in résumé is not the best choice in terms of Polyval

OVERALL OPINION

I've had ten years (ouch ... I'm getting old and at the time he has really matched my expectations ... over time, tastes change and I am a bit "lassquot; sound. I" bypasses "the last few months I prampli replaced by a Rocktron Voodu Valve, since it takes advantage of a second youth)

Now I think it does not compete in terms of possibilities with the current models but ... I think ultimately it's an amp that has some me (this is rare) and I am a hard Sparer

Everything has been said ...

UTILIZATION

Using relatively simple
just a little tampering, come for all amps of this kind

SOUNDS

This is where we fall into hell ..
I remember when I started the guitar 10 years ago, and dreamed of before this monster (such waaahhh, Quan I have the dough, I'll buy a JCM 900 ...)
Ben and after playing it, it falls very low very quickly ...
that mean?
At first I thought I could not fix it ...
Actually, no, the sound is really crap, but like really shit
The sound is not clean, it's not versatile, and at least play the grunge garage with a distortion pedal dod grunge home (that is, if we seek a sound filthy), I consider this amp as unnecessary
the only way to make it sound, c him hook up a preamp in the loop, and there, depending on the quality of the preamp, it rocks well
basically, I used this amp mostly for its power section
it can be very interesting, if you have a good preamp, otherwise it is useless
So, I put four because my preamp sounded good in the power section

OVERALL OPINION

I think I've said it all ...
it can be a good plan for a OCCAZ cheap if there are connecting a preamp ..
Too bad, it looks pretty class
In fact, it must be put in a corner as a convenient and does not connect ..

JCM900 4100 dual reverb series.
all lamps (3 premp, 4 amp).
100w power.

UTILIZATION

My utlisation is notament is for the big rock, rock and variety (style-M-). with an epiphone Lespaul Standard.

SOUNDS

The sound should lead to a suited my style of music (Hendrix, ...).-M-warm sound.
the guitar part with a wah-wah morley and that's enough for one of his mythique.pas need to go through tons of pedals and rack ...
its clear this is not the same, because the amp crunch right now (especially with the wah-wah). but the sound quality is good trs.

OVERALL OPINION

As the pass transistor, a hybrid and a lamp (all from Marshall). I am a marshall trs typ. This head is perfect for me.
those who say it's not great do not understand the approach of a notice

Good, quick reminder:

This is an all-tube amp, 100 Watts, 2 channels. The connection is simple: Between guitar, footswitch, and rear of the BTE, an effects loop, two speaker outputs, and power supply. At rglalge and effects, it is the bare minimum: gain, 3 band eq and reverb.

The eq is not efficient trs, and rverb plutt brittle over time

UTILIZATION

The use could not be simpler. It's true plug and play. One branch and it works!

SOUNDS

Ha! This is the beginners that the rat race! Personally, I play blues, pop, rock, and especially the progressive mtal mtal and industrial. I jou on many amps (Mesa Boogie, Line 6, Peavey 5150, ...). And I came back to Marshall! Why? First, we must prciser that no two sound like Marshall. For some reason. Then it's an amp that is "tame." Also, you really think in terms of torque guitar / amp. Personally I play a Les Paul and The Beast Custom Lag. Finally, this amp does a brilliant Vincent compltement tampering by the Liberty Rock Studio. Power Has compltement redone, the circuit also rverb, and the amp is fitted exclusively lamps EH. Feedback, there is no extraneous noise and the sound is warm, dynamic, rich, either in clear sound with distortion. Especially since it all out on two Marshall 4x12 cabinets. For résumé, I get a sort of mix between a Mesa Boogie and a JCM 800. During live performances of my group, I actually many guitarists who come to me APRS saying "we never heard a Marshall sound like a. .."

OVERALL OPINION

I use the bte the past 1 ½ years. I love the sound, versatility and its ability to highlight the guitar that I plug it. APRS trying moultes combination (Mesa Boogie Rectifier, Peavey 5150, or POD + power amp), I fell madly in this amp bought used for 600 euros with two 4x12 cabinets! At that price the more, has not refuse, even now and I plan to buy one deuxime!
