Marshall 4103 JCM800 Master Volume Lead [1981-1989]
Marshall JCM 800 to the hot most highly use Marshall amps in existence. It is a guitar player's dream because it takes petals so well and is the perfect platform for modification. This is a great aunt for any gigging recording artist and you've heard this and if you've ever listen any rock 'n roll album on the radio or in your car. This is a great classic martial tone and the sound and voice minutes and couldn't be any more perfect.

These answers such a delight to hear him play. They have a fast attack which means that the notes respond very quickly to your strumming and picking. These are greatly voiced guitars for heart rock and metal and can be modified in so many different platforms.


This is 100 W version of this amplifier has to input for one for high and one for low I'm not exactly sure how many decibels below takes off from the high. These amplifiers take petals extremely well. I love hearing them in different scenarios whether that be load to mid indie rock all the way up to drop tooting metal. They're very easy to dial and you just need to use your years to find that certain sweet spot to marry your speaker cabinet to your guitar into whatever distortion pedals overdrive petals delays phasers Flanders course pedals or any other effect that you might have.


I love the tone of this amplifier more than probably any amplifier I've ever played. It has a great voicing an great tone for most music. I play mostly metal hard rock to this guitar amplifier fits me perfectly. Slap a nice boss SD-1 pedal in front of this amplifier and you get a great 80s or even 90s are today hard rock tone. You don't even have to have this amplifier modified, it sounds so good with that pedal and a good superstrat guitar.

I generally like to play around with the travel on the presence on these amplifiers because depending on where you have it is depending on how much presence you need. I permanently have the preamp again all the way maxed out in my volume level to the desired room volume point. Generally I'll have the bass pretty crank pretty high in the sand depending on what speaker in guitar I'm using. The news I usually four right around middle and that gives me a good overall hard rock tone that will be very pleasing to my ears.


I highly recommend this amplifier to anyone looking to buy one of the best Marshall platform amplifiers in existence. This is an excellent amplifier for modification and the perfect cornerstone to any rock guitarist rig. Any use section you can find these amplifiers as low as $600 which is where I bought mine at one point. I've owned several these amplifiers for up throughout the years and I would keep coming back to them no matter how many amplifiers I try out or own. It's a great starting point for most guitars if you want that Marshall tone that is been familiar with most of rock 'n roll history than this is the amplifier for you.

No need to think: one branch, play and attention to puissance.Donc not made to play at home, prefer to keep your castle isolated in the countryside.


Its clear moyen.Pour the rest; crunch, overdrive and saturation was the beautiful sound typical 70/80 but you have to push the animal if it is any 'without much expression. This is an amp made for the scene before all that goes with both a guitar with pickups SB or DB


I played this amp at the time and I prefer it to his successor JCM 900.
At the time it was expensive for many scholarships but it is a good amp rock, blues, hard and reference.

Marshall 4103 JCM800 Master Volume Lead [1981-1989]
50W all-tube amp with 12 hp "in a combo.
No effects, branch (between the high or low) and we play.
I do not know exactly what I was silent version (when in doubt you abstain).


The configuration is simple archi-because there are not too many channels and buttons to various functions.


This amp's me on a lot of points. First the precision. Even if it is good for a marshmal, it remains to what one would expect of a head lamp.

The clean is bright and plutt cool is just what saves this amp. The distortion is quite dcevante, expected gain, "No, when a s'arrte comments has become cool," but demonstrated an overall heat well. The grain of the disto vaguely remember groups years 70-80, it's also a bit further highlight, lgrement biting and voluptuous, it has to be known.

It must be pushed to speak in the corner crunch, which then break existential problem for tenants of public housing

Note that the knobs are imprcis, the sound crackles when they are handled. S'croule volume during use, it is tantt l. .. tantt not, why no one knows. Of noise in bigextra-bonus on top of that ... brief ... has not fly high (a marshmal what)!

It is a good basis for the distortion pedals.


Found on the floor, I do not regret trying. But I quickly given a p'tit young in the audience (there happy now the silent j'espre he will not mind then hihihi).

It will be a good basis anyone who wants to start guitar with something that makes noise, the star-academy or the soundtrack of the teletubbies.

Not ... j'dconne ... in fact it is quite well suited for pop and mo, to ballads, jazz and blues, funk and rock (fusion) low gain. It also has enough heat to a. Simply, it remains below the average of its competitors.

Note [5] is the average home
