Hello Everyone, 

I bought the Marshall code 100 Head as a second hand after watching the positive reviews of it, and I really liked the sound and its features!

I plugged it to a 1 x 12 Cabinet and it works good except for my big disappointment with the hissing white noise that i was getting even when the master volume knob on the amp is turned all the way down. 

I tried every simple solution that i could come with, including turning off the computer in the room, I tried resetting the Amp to factory settings,  I even installed the new firmware from the marshall website.  but none solved this issue.
Does anyone know the solution for this problem? 

Thank you very much in advance

Hi

I’m trying to decide which amp to get. My ultimate goal is to get out there and start gigging. I love big, dumb rock songs and have more or less narrowed down my search to a JCM 800. Here’s where my dilemma comes in.

For the same price, I can get either 1990 JCM 800 (50 watt) and a 1960A cab of indeterminate year or the little SC20 amp and cabinet.

Since I want to start gigging out, I am leaning toward the full-sized amp, with worries that it might be too loud even. However, since most of my playing is at home, I like the idea of the lower powered SC20. The one I played sounded super good at around-the-house levels. I am worried it won’t suffice if I try to gig with it. I have never played through an 800. (Or any half stack, for that matter. Right now my main amp is a Deluxe Reverb.)

So I guess what I want to know is which one is the better option for me? Do I prioritize stage volume or home volume? Does anyone even need a big, loud amp nowadays, or is a smaller, miked-up amp better in the long run?

Hello,

I have a Marshall DSL40C-U and love the AMP. 

How do I plug and external cabniet into the AMP and which cabniet from ? is compatible?

There are several input output jack in the back of the AMP.  I'm not certain which one to use.

Thanks in advance,

John

Hey all.

New to the Code.  Tryin to navigate the website some.  
Question about user uploaded preset settings.

 At the bottom of the setting description, I've noticed many times there will be an icon or pic of a Marshall cabinet with a red X thru it.  My guess is that it means the cabinet simulation is turned off..??

Any clarification would be greatly appreciated.

Thanks

Has anyone used a small pedal amp to input the headphone to a amp like the electro harmonix 5MM.  I saw this done on a Spark amp to connect to a speaker cabinet.  I would think I could do the same on the CODE.  Adapt the 1/8 to 1/4 to go from headphone jack to the input on the 5MM and then in my case that speaker cable goes to a mixer.  I know this amp does have a dedicated line out to do what I want to do.  So I think this would accomplish the same thing.  Any thoughts good or bad?  I plan to try as soon as I get my hands on a small pedal(not a stomp box, just a pedal size amp) and configure the cables to go from 1/8 headphone to the 1/4 input on the amp.  I'm not an electrical engineer, I just need a "line out" if possible.  Should work.  Thanks,

Hello,    New amp I procured and I am hoping to get some Q's answered regarding. 

It did not come with a footswitch and being new to all of this I do not know why I need one or which footswitch to get ????

Also, I was told by the original owner that it is quite than it used to be and may need a new tube.   Also do not know which way to go with this ...   

Last point is when switching over from clean to overdrive it is buzzing and I am not sure why...

After hours on youtube and reading the instruction manual I am even more confused. 

Thanks in advance for comments/advice.

Hello, I recently ordered a used JCM800 Model 1580 Bass Cabinet.  The seller's photos show it with one 18 inch Celestion G18Q-400 speaker.  I've learned that they were made in the 1980s-90s, and came in mutliple speaker configurations. Mine is the 1x18.  I'm assuming the cab originally came with the G18Q-400?

Would really love to know:

1. the performance specs of the G18Q speaker (Celestion.com didn't have any info)

2. whether the round port cut in the baffle of the cab is original. 

See picture below.  Thanks!

I recently purchased a code 100h.  I've noticed that with the cabinet simulation turned off, the amp is incredibly fizzy and bright.  I am running into a 2x12 with Celestion Vintage 30s.  Is there a way to tame this high-end shrillness without having to resort to running cabinet simulation through an existing cabinet?

I have two identical Marshall DSL 100 watt heads. One of them was starting to crackle when I turned up volume on either clean or distortion channels. It  finally quit and assumed it was just dust in pod. However  a week ago turned amp head on and neither green light for clean channel or red light for distortion channel were coming on and no sound at all from either channel coming coming through speaker cabinet. Trying to get some help on what could possibly be wrong causing me to lose sound from amp head. Thanks

I noticed there is an emulated out on the back of the 20Watt Dsl head. From reading the .pdf manual, I understand that the head needs to stay connected to the speaker cabinet. So I know to never un-hook it, however - My questions being - 

Do I need to be in Stand-By mode to actually use the headphones? If not, will the sound still come from the speaker cab? 

Also, can I just plug my headphones directly into the Emulated Out? the .pdf manual says the Dsl20 Emulated Out supports Headphones. But I've seen people comment in other places that you need a headphone amp that increases volume or something. I haven't been able to test with headphones yet, and I kinda' wanna' get the right answer on this before I try. Thanks. 

Loving the Amp and Speaker cab though haha. Just came in yestreday. 

I have 3 combo amps each with a single 16 ohm speaker. baffles the heck out of me why Marshall would recommend a 2x12 8 ohm ext cabinet. I want to run both the internal speaker and the ext cabinet at the same time. I would like to put 8 ohm speakers in the combos to match the ext cabs. I have a JCM 2000 DSL 401, a DSL 40cr And an Origin 1x10 20 Watt. Can a16ohm speaker be upgraded with an 8 ohm speaker in these combos and if so what speakers would you recommend. Any additional suggestions or information is most welcome.

Can you please show me which jack i should use to plug my head into the cabinet. I have a new 2 weeks old, Marshall DSL 20 HR Head with the MX212RR Marshall cab. On the back of the head it has 3 jacks for to plug into the cabinet and i dont know which is the best. It has lines pointing to the OHM's but the lines dont line up with the different ohms and its hard to tell which one to use. Anyway of sending me a picture or explaining which jack i should use please. Ive looked every where, youtube, online googled and cant find any info on which jack to use from thr back of the head to plug into the speaker cabinet. Thank you

If I change to an 8 ohm V-series speaker in my DSL40CR, do you foresee any problems using it with an 8 ohm MX212AR cabinet , if I plug into the two 8 ohm speaker outputs ? .......................thanks............RD

I have read, when using the direct out there is no need to have a cabinet connected to the head.

My question is: is this in general or only when the direct out is engaged?

I would like to slave another amp from the effects send, without using a cabinet connect to the origin 50 head.

I wonder if the dummy loads is always on

Hello everyone, I own the Marshall CODE 100H and CODE 212 cabinet.I really love this amp, but I find the MY GATEWAY web page interface to be somewhat awkward to use. The following are issues that I would like to see changed.

1) On the My GATEWAY web page, the preset list at the top is arranged by columns (as it should be), but the MY LIBRARY list below that is arranged by rows.

?

2) There is no indication in the MY LIBRARY section on the MY GATEWAY tab whether a preset is or isn’t in the MY GATEWAY list.

Greetings,

What is the measurement AT THE TOP of the MX212AR vertical cabinet FROM FRONT TO BACK ?

Thank You................RD

Hello everyone from Portugal,

I have an Origin 20c Amplifier that I purchased new last year. It must have been old stock because it appears the manufacture date was 2018. I believe this unit has the faulty Jack wiring since the labels for the external speakers do not match the owners manual (2 8ohm jacks, without the line indicating 16ohm for both). My question is, will this unit work with a single Origin 212 cabinet, assuming I unplug the internal speaker, or do I need to get it repaired. If it will work, which of the speaker jack should I use, the one in the middle or the one furthest from the 16 ohm Jack

Hi! I have a question about CODE 100H. I need to play directly in mixer but it hasn't a DI exit, can I use it without a cabinet? If I can, how can I do it? If I don't use cabinet, will CODE be damaged? Thanks for your help. 

I have a Marshall Origin 50H, its about 7 months old and I've used it perhaps  maybe 10 times total for some pretty low volume playing and never used on anything but the lowest 5w setting. I'm using it with a proper 16 ohm Celestion cabinet and proper cables and playing for about 40yrs so know what I'm doing, well, most days that is lol! :)

Anywho,  after about 10 minutes the volume drops WAY off and I'm assuming its a power tube since the level of gain doesn't change at all,  just the volume and it gets real compressed. 

Since I've only had the amp 7 months, would the tubes be covered under warranty in any way? I would hope so due to how little I've used it, thanks for any insight.
