Please contact us with your amplifier model and serial number and we will be able to supply you with the information you require.

How can I set my controls so I have the same sound as my favourite guitarist?

Unfortunately most guitarists tend to use more than one amplifier and guitar. It is impossible to have all the individual settings as these can vary from amplifier to amplifier and in certain cases are guarded secrets. Also, often a guitarist’s playing technique is a vital part of their sound.

Which Marshall amplifier does my favourite guitarist use?

If your favourite guitarist is a Marshall artist then go to the Artist page on the website for information on what Marshall amplifier(s) and cabs they use.

Will it damage my amplifier if I turn the controls to maximum?

All Marshall products are designed to work at maximum, but if you run your amplifier at maximum you can shorten the life of certain components, such as valves. But running an amplifier at maximum should not damage it.

What FX pedals would you recommend using with my amplifier?

We recommend contacting your dealer so you can try various FX pedals with an amplifier to see which ones suit you the best. Check out Marshall stomp boxes here.

What footswitch in your range do you recommend to use with my amplifier or combo?

If your unit is designed to use a footswitch your local dealer should have this information and will be able to supply you with the correct footswitch for your unit.

Is there an optimum position to set my controls to get the best sound from my amplifier?

There are no set positions for the controls of your amplifier. Choose the control settings that you like best and best suit your playing style.

If I replaced the speaker lead between my amplifier and speaker cabinet improve the sound?

Providing you are using the Marshall recommended speaker lead, and that this is replaced on a regular basis, you should not notice any loss of quality due to the speaker lead.

When using my amplifier in my bedroom if I turn the controls up high it squeals uncontrollably. Is this a fault?

The noise you are describing is due to the distance your guitar pickups are from your amplifier. The louder you set your amplifier the greater this distance needs to be. This will also depend on the kind of pickups in your guitar. The best advice I can give, if you intend to use your amplifier at higher volume, is to move away from the amplifier as far as possible. However, sometimes, certain kinds of feedback can be desirable.

Is there anyway I can plug two guitars into my amplifier at the same time?

Most Marshall amplifiers, with the exception of our AS acoustic series, are designed to take one guitar. Connecting two guitars into the same input to use at the same time will effect both the quality and the level of sound, and could also damage your amplifier’s input circuitry.

Does lifting my cabinet/combo off the ground affect the sound?

Lifting a cabinet off the ground, depending on the height, can increase the bass response and help to spread the sound. If you intend trying this we recommend you make sure the cabinet is securely supported.

What is the best way of transporting my amplifier?

Ensure the controls cannot be damaged by your amplifier sliding or rolling in either the car boot or van in which you are transporting it. If you are transporting a combo or cabinet ensure the speaker is facing down and the controls on the combo are not put under any strain from other equipment being transported. If you are transporting a cabinet with castors in a van, place the cabinet face down. If this is not possible, transport the cabinet on its side – never on the castors. If you transport your amplifier a lot it might be worth considering having it flight cased. Speak to your Marshall dealer for advice.

When using my valve amplifier is there a correct way to switch it on and off?

Before using your amplifier please make sure you have read and understood the safety information in the user’s manual. When you are ready to use your valve amplifier, connect the speaker lead to the cabinet and head. If you are using a combo, ensure the speaker lead is connected to its socket on the back panel. Connect the power lead and plug your amplifier into the mains supply. Ensure Standby is switched to the ‘on’ position. Next to the Standby switch is the Power switch. Switch this to the ‘on’ position. Now wait at least two minutes before switching Standby ‘off’. With the Power ‘on’ and Standby ‘off’ your amplifier is ready to use. If you are leaving your amplifier for a short while make sure you switch Standby ‘on’. This will keep you valves warm, which will help with performance and valve life span. Never leave your amplifier unattended when it is switched ‘on’. To switch ‘off’ your amplifier, switch Standby ‘on’ and then the mains switch ‘off’. There is no need for a delay between these two operations. We recommend leaving your amplifier to cool down for a minimum of 10 minutes before moving.

When using the D.I. socket on the back of my amplifier does the speaker cabinet need to be plugged in?

We recommend a speaker cabinet is connected to Marshall amplifiers at all times.

How can I connect two amplifiers together?

If the two amplifiers you wish to connect together have FX Loops you can in certain circumstances plug your guitar into the input of one amplifier, take a screened lead from the FX Send jack of that amplifier into the FX Return of your second amplifier. This makes the second amplifier the slave unit. None of the preamp controls on the second amplifier will function. The Master Volume will control the output of the second amplifier. The tone controls on the first amplifier will affect both. Although, this will vary from model to model. If one of your amplifiers is fitted with a D.I. socket this can be used instead of the send socket on the first amplifier. You must however ensure that both amplifier have a speaker connected at all times. Failing to do this may cause damage. If in doubt, contact your Marshal dealer for advice.

My valve amplifier gets hot when in use is this normal?

Valve amplifiers will generate heat. Because of this they are fitted with a grill at the back so it is not possible to touch the valves. When the amplifier is in use it will get to a working temperature which can and will be hot to touch. This is quite normal. If you are concerned contact your Marshall dealer and they can check your amplifier is functioning correctly.

Do I need a speaker connected to my valve amplifier all the time?

We recommend a speaker is connected to all Marshall amplifiers at all times while power is on. Failure to do this can and will cause damage to your amplifier.

Does it matter if the vent on the top of my unit is covered up, as I am concerned about things being spilt into it?

The vent on the top of your amplifier is for valve ventilation. Valves get hot and need to be ventilated so they run at the correct temperature. The top and back grill must have good air flow at all times. Restricting air flow through your amplifier can and will cause damage.


This will depend on the model of your amplifier. If you supply us with the model number we can tell you what materials are used to construct your amplifier.

What amplifiers in your range are made in England?

The amplifiers which are manufactured overseas are the MG Series, AS acoustic combos and the all-valve DSL Series. All other amplifiers are manufactured in the Bletchley production facility in England.

Is it possible to come and have a tour around the factory?

Please contact our Service Department and they will be able to arrange a tour for you. Factory tours are strictly by appointment only.

Where is the best place to store my amplifier when not in use?

We recommend you store your amplifier in a dry, well ventilated space that does not subject your amplifier to extremes of temperature. Under NO circumstances must your amplifier be stored where it will be subjected to moisture.

If my unit is not used for a long period of time will this cause any damage?

Storing your amplifier for up to a month should cause no prolonged damage. If it is stored for several months certain components, especially in older units, may need replacing before re-using. If you have not used your amplifier for over six months we recommend it is serviced before use.

Do you do a cover for my amplifier?

To check whether there is a cover available for your amplifier please contact our Spares Department on 01908 375411.

Can my amplifier work anywhere in the world? If not what do I need to do to make it work?

It depends on the model of your amplifier. Certain models have voltage selectors fitted, whilst others need the mains transformer re-wiring, and other amplifiers will need to have the mains transformer replaced. All amplifiers will need the correct fuse for the country they are being used in. All work of this nature MUST be carried out by a qualified engineer.

When changing channels on my amplifier there is a delay. Is this normal or is there a fault?

On some of our models, due to the output power, there is a small delay added to reduce any noise when switching from one channel to another.
