First shot! Eternal lock sound! Marshall jcm800

A model that appeared after JCM 800, which has boasted the best selling of marshal ever, and appeared as a 90's Marshall face. It is introduced in many studios and live houses, and is still currently used in active duty. In recent years, I think that there are many people who have actually been touched because they were more popular than JCM 800.

Modern massal, and one of the modern high gain amplifiers are a model that has become a "recent marshal ..." and also a model that has been doubted from a monthly marshal fan.

However, when I try again today, it will be reconfirmed that it is a model colored with many attractiveness, such as the sharpness of the sound, the goodness, toughness, and cost performance. Of course, a sharp drive edge that can be used enough for high gain models in recent years is a powerful character that impresses its own presence. We talk about the actual results that are "face" representing marshal since the 1990s.

Appearance background

JCM900 was announced at NAMM show in January 1990. In the 80's, after the JCM 800 recorded in the world in the world, this name was given as a pronoun of the 1990s. Once, the times are a hundred rose of music called Herdlock and Heavy Locks for more hard sounds. This year that Metallica appeared in the Grammy Award. Everyone in the scene did not get tired of the gain of existing amplifiers, and asked for a higher gain model.

Jcm900

Until then, Marshall was successful in JCM 800, but as late 80's, many players were not enough in normal JCM800 gain. For this reason, the Movement of Marshall remodeling happened, and it has previously mentioned that a lot of capable amplifier builders such as line Holt Bogner and Mike Sordano were mentioned, but the other side, everyone is advanced to that The rough remodeling marshal was also beginning to flood, not necessarily the technology. It seems that there was something that has rose up to noise along with the gain, it was terrible or terrible, or the life of the amplifier itself. Under these circumstances, Gym Marshal, who realized the need for high gain model, first announced the Jubilee series as the 25th anniversary of Marshall established in 87 years. At the time, at the time, it is expressed as "the most distorted marshal", and we will be well received by the top artists at the time of Bon Jovi's Richie Sambora and Guns N 'Roses slash. The Jubilee series should have a year-only model of the 25th anniversary, but production will continue to 89 years for the great needs sent. And in the coming up of the 90s, Marshall announced a high gain amplifier newly designed as a new era sound. That is JCM900. Moreover, at this time, the concept of the 30th anniversary model following Jubilee was also kneaded.

Come on JCM900 fit yourself?

As with JCM800, there were many 900 variations. But here is a big deal and two patterns. High Gain Dual Reverb (2 Channels told 2 Channels) and High Gain Master Volume (Roughly, one channel). Each created 50W and 100W, and a head type and a combo type.
The High Gain Dual Reverb model can also set a revival for each of the two gains that can be switched on the foot switch and two masters. That is, clean and driving can be switched, for example, cleans are deepened, and the drive can be set to be a revival (or off). This model is the most introduced, easy to use, etc. The JCM900 seen by the practice studio etc. is also good.
The High Gain Master Volume model has two gain and two mastervoles, but only the master can switch with the switch. Doca-N! It can be a wind of ... with a large sound, but it can not be used like switching clean and drive. If distorted, if it is distorted and cleaned, there is no way to change the gain settings. (But this solo mode, Master switching is quite modern, with modern models, and Koch.) Two gains are quite hard in two-step gain that works simultaneously on one channel It is possible to create distortion. It would be nice to say early story and distortion exclusive machine.

Jcm900

May I strain? Gain scale up to 20!

As a function common to both, there is an OUTPUT VALVE FUSE that is the HI / LO switch to switch the leveled effect loop, direct out, and 3 pole / 5 pipes, and the power tube protection circuit that is first installed. This is a role in avoiding overload by skipping a vacuum tube that is operating normally, avoiding overload by skipping the tube tube that is operating normally, and it is possible to prevent damage to other vacuum tubes. I have.

Example: 4102 4 = High Gain Dual Reverb, 1 = 100 W, 2 = 2 Speakers. For this reason, it can be seen that it is a combos amplifier equipped with 2 speakers in a channel switchable type.

What is SLX?

A model with the notation of "SLX", such as 2100SLX and 2500SLX, can also be seen well. This is normal 2100 or 2500?

Jcm900

A monster amplifier that can be said to have decided to determine the subsequent scene in 1991, the next year, the JCM900 announced. MESA / BOOGIE DUAL RECTIFIER and PEAVEY 5150. Two major high gains that can be said to have changed their history will be released at this year. I do not know if it was impatient, but Marshall also counterparted a high gain match or 1993, a more pre-tube in the preamplifier stage of the High Gain Master Volume model. It has become a more high gain specification with a plus two amplification stages. And SLX, which means SUPER LEAD X-TRA GAIN, was described, and the color as a heavy drive machine was strengthened.

Jcm900

Three pre-piles of previous models

Jcm900

SLX has four pre-tubes!

tubeAlso, the power tube used in all models of the marshal is changed to EL34 to 5881. This is also said to be due to the lack of stable supply of Sobutek, which is the Russian vacuum tube manufacturer who was mainly used by this time marshal, but this change will be a tone with a clear and solid "Bakibaki", which is 90 I went to a typical sound of the age of age. This specification continued to the EL34 specifications since 1998, continued to introduce Russian vacuum tube maker and Svetlanana, as Marshall.

EL34 and 5881

Although overlapping with the above, the power tube is switched from EL34 to 5881 in most models of the marshal vacuum tube amplifier from around 93. JCM900, of course, 5881 was used at 1959 SLP and 1987x in Vintage Leisy Shi, which is also a fact that there was a certain core fan discourse. The negative idiom of "recent marshal ~" also has a sense that this time has occurred at this time.
As a characteristic of sound, 5881 is called 6L6 high-trust tube, and is a relatively distorted tone, and it is a tone that is a clear tone that is difficult to distort, and even if the volume is increased relatively mild, a rapid sound change is less likely to occur. This is suitable for dry clean sounds and solid distortion sounds, and historically familiar tubes with fender amplifiers such as Bassman. Many models of MESA / BOOGIE and Peavey 5150 will be used to say a tube that represents American Sound.
On the other hand, EL34 is a tone where the teeth is sharply bitten at the time of small volume, and when the volume is rising and the tone starts to clip, the tone changes rapidly and transforms into a thick and sticky sound that is closer to the middle. In addition to being a tube that colored a glamorous part of the previous marshal history, there was also an amplifier maker representing UK such as Hiwatt and Orange, especially in Japan, "British sound is EL34" There was also a mythical thing I said.
Because it was a change to Marshall's 5881 in such a back, it is certainly a part that can be a critical voice from an eager british rock fan, and it is certainly a part that can be sympathized, and only a vintage reissue of 5881 specifications is sold in real time I also remember that I had a little lonely feeling. It was rather than the sound aspect, but it was a mental part. But fortunately, almost all 98 models return EL34, and the Vintage series, as well as the JCM900, JCM900 will be the EL34 specification again. This is also taken over after the subsequent JCM2000.
It may think that it is such a modern, but when I saw the 5881 specification JCM900, I was a little nostalgic. The ratios of the high gain amplifier are highlighted, and you may hear the "more JCM900 sound". A little talk is that it is attractive when you listen to the sound of the 5881 specification 1959 SLP again now. At that time, I think that it smiles that it was disappointed with it.
There is such a translation that both versions of 5881 and EL34 exist in the interesting point of JCM900. Early (until around 93) and in recent years (98 years later) are EL34 and 5881. If you see it with studio etc., "Which is this?"

>> Amplifier using 5881 not limited to marshal!

>> The same EL34 feels like this

Jcm900

The 5881 period model has a label with 5881 usage at the top.

JCM900 family?
In fact, it seems to have been developed at the same time 30th anniversary model 6100

Jcm900

This model is not a JCM900 series, but it should not forget that it has a deep relationship with JCM 900. Blue leather is 6100 impressive. This is the first three channels of marshal and crunch / leads. MIDI is also equipped with a model ahead of the world. The appearance is 1992, which is the 30th anniversary of Marshall establishment after 2 years from JCM 900. Now it seems that three channels are commonplace, but it was a breakthrough.
Actually this model, development itself was almost the same time as JCM900. However, in order to release the JCM900 series worldwide, it was also possible to produce in parallel with each JCM900 model, or it was said that it was preserved until 92 years of Aniversary ear. As mentioned earlier, the times are also changing the high gain boom. It may also be a aim for the movement of other brands after JCM900 release.
It is 6100, which has appeared in such a flow, but it is a three-channel model manufactured at a fairly early stage, with a full independent three-channel specification. Channel 1 is clean with two modes, and a clean tone that is familiar with marshal and fender can be selected by midshift and bright control. Channel 2 is a channel that should be said to be a rhythm sound, a vintage style that is reminiscent of JTM45, JCM 800, which is a typical sound, and JCM900 wind can be choked. Furthermore, in Channel 3, it is not possible to say that it should be said to be the strongest in marshal history. This sound evolves the JCM900 and is also considered to be the source of SLX mentioned above. Thus, the 6100, which has been renowned from the traditional tone to the latest sound, was surprised at many musicians, and is also known for the use of Joe Satorian or Gary Moore, and is familiar as "blue marshal".
Lots made as a limited-time limit for Aniversary are fully gold-plated specifications, and chassis, as well as tube covers and tube springs. The cabinet front logo also used the Gold panel. This specification is only 500 in the world (800 combo), and is called by the name 6100le. Since then, except for blue leather, the normal chassis was produced from the end of the Aniversary Year, and from the following year to a 90's final stage with black leather.

With the attraction of JCM 900 again

The JCM2000 series has been released as a new model that looked at the 21st century in the 20th century, 1999. Even now, the ability to say that it is also a flagship existence, JCM2000, which is a young player, and it appeared to be a fortune veteran, and the age of JCM900 was over. Certainly, as JCM2000 is spreading, many models of JCM900 such as SLX have gradually disappeared. However, the High Gain Dual Reverb Series 4100, which was representative in JCM900, is still produced. From 1990, there was no specification change from 1990 to 18 years after the change of the century. While the music scene changes a variety of changing, it can be said to be another long-sales. The reason is that if you rent a marshall official language, it means that "the sound image is absolutely thick and hiding the vintage DNA", but this expression will not be false. The "distortion" amplifier then exists countless, but a tone that the natural drive has become high gain as it is. If you say, the world's most hardest "overdrive" amplifier may be the characteristic of JCM900.
If it adds it, its simpleness, ease of use, and easy to understand when you get it for the first time is a great attraction. In addition, it is not a person who is not too fever, but it is difficult for the sound axis to be broken even if it is used for a long time, and there is a reason that there are few troubles, etc. increase. In addition, if you add an author's personal view, it should be said that it is the most reliable model to connect through a return using a rack type preamp. If you are a place where JCM900 is placed, there is always a peace of mind.
Such high reliability JCM900. Although it is not a pure vintage sound, it is not a madness modern hair gain, but it is no doubt that it is the ability of the shade that has reliably supported the scene near 20 years. "Simple" "Tough" "Hard" ... All words required for lock music are in JCM 900. I can not think so.
