Hi! 

I bought the Major III bluetooth headphones but I have a big problem when connecting them to my windows 10 computer. My sound is terrible when using the headset. If I deactivate the hands free telephony setting in the device's properties it switches to headphones and the sound is perfect but the microphone stops working.

Is there a way to fix this problem?

I am experiencing terrible interference when trying to use my Code 50  via Bluetooth / Gateway (Apple) App while recording on my Mac in Logic Pro X.  I am using a microphone to record the Code 50 and using the Bluetooth to change patches.  The clicks/pops/noise/interference is loud enough to interfere with the recording process.  Perhaps a DESKTOP (Apple) Gateway App via Code USB might be a solution for all users experiencing similar issues?   I am running the most current Firmware.  Any current solution to my noise issues?  Thank you. 

Hi there,

I had a Marshall dsl40cr brand new and out the box it "hissed" and "wooshed" quite bad, so much so I had to send it back.

I was sent a replacement that was alot better, but still a touch of noise.

This isn't electrical noise or interference - I know what that sounds like - this is something different.

It's only recently I've been too bothered, as it seems a lot of people have this issue.

My second issues is, when swapping between the 2 master volumes there is a popping noise - that's regardless of if 1 is higher than 2 or vice versa. It's like a static pop and happens via footswitch or on the panel.

I been reading the noise can be due to caps and resistors that need swapping and the popping is due to a faulty controller. Surely if these are known problems, this should be covered.

Any help is greatly appreciated!

Thanks!

What options are available to replace the stock 4 ohm speaker that comes in the Code 50?  I would like to upgrade to a Celetion or something similar.  The stock speaker flutters at volume when using the heavy distorted/gain presets.  Any recommedations?

Hello,

I've noticed that there is rattling/jangling coming from the amp (not the speaker) when playing notes between low  A and C and their respective octaves above. It sounds like it is coming from the EL34 valves - is this due to the way that they are mounted without spring dampers? They have not gone microphonic as far as I can tell, and are otherwise performing as expected, so I feel this is more a mechanical issue with the chassis/mounting, or it's just an undesirable characteristic of the valves themselves. What I'd ideally like to know is, do all Origin 20Cs do this or is this the first anyone has heard about this?

I've removed every external variable there could be, moving the amp to another location and isolating it from floor vibrations in the studio. I've taken the 'amp' out of the cabinet so that I could lightly tap the valves, and check the screws around the supports are not loose. You can generate the rattle (or very similar) just by tapping lightly with the handle of a screwdriver, on both valves. This is what I was expecting if it was just physical vibrations from the speaker causing them to rattle in sypmathy. The rattling sound does not get amplified, so it's not in the audio path.

It's enough to be offputting when tracking/practicing in the studio unless pushing out really high volume so that you can only hear the guitar. I play fairly clean a lot of the time so it is more obvious under those conditions.

Would really appreciate some advice. If the answer is, "It's the same for all and there's not much that can be done..." then ok, I just need to know. That said, I spotted there was some sort of similar issue perhaps on Class 5 amps that a kit was developed for to resolve? I may have misunderstood though.

If there is any further mechanical troubleshooting to be done then please let me know. I wouldn't want to void the warranty status if possible. For what it's worth, I'm a systems and support engineer for a large format mixing console company, so I'm competent enough to poke around as required... just figured someone may have alreday solved this one before I carry on!

Kind regards,

Ed

Je n'arrive plus a faire reconnaître mon téléphone dans l'appli gateway Marshall

Le téléphone se connecte via bluetooth mais l'appli ne me donne pas accès au réglage / pas de connection

Je ne plus piloter mon ampli avec le téléphone alors que cela fonctionnait parfaitement auparavant.

J'ai fait une mise a jour de l ampli par USB 

Quelqu'un rencontré le même problème ?

Merci pour votre réponse.

Éric.

Hi there,

I found an old Marshall 2236B cabinet that has 4 greenbacks and a big red horn. (one with name celestion and 3 of them are rola celestions).

All elements 16 ohm.

The grill cloth is basket.. light brown.. and this cab has had a small marshall logo on the center..  fastened with 5 pins.

I can only find a date stamp on the celestion (without taking them loose).. it says December 1970.

Cabinets serial is 30274

Could you please tell me how many were made and how rare this is? I guess these were made between 1970-1974? Right?

Any idea of todays value? All elements working perfectly and casters missing.. you have any casters left for these? =D

Best regards:

I purchased a Marshall CODE 100H + 212 Cab recently.

I downloaded the Marshall Gateway app and have created a My Marshall account.

The Amp came pre-loadedwith a 100 presets.

The Marshall Gateway app also came pre-loaded with 100 presets,

but the Gateway app presets are different from the ones in the amp.

I synced the 100 presets in the Gateway app to my "My Marshall" account Library.

I have edited and saved some of the Presets on my Amp.

I want to transfer the edited Presets on my Amp to my "My Marshall" account Library, and then put them in my Gateway app, 

How do I Transfer a Preset FROM my CODE Amp to my "My Marshall" account Library?

I see the option to transfer a Preset from My Library to the Amp,

and I understand how to manage / organize the Gateway app presets from the Library,

but I don't see a way to put a Preset on the Amp in the Library.

Do I have to manually re-create it in the Library?

The My Gateway online interface is  great for managing / organizing the Gateway app presets from the Library.

It would be useful if there was as similar interface for managing / organizing the presets on the Amp, when connected via USB.

I have had my amp JCM 2000 TSL 122 combo for a few years. I used it occasionally when I first acquired it (around 2008) and then fairly regularly in a band for about a year in 2009/20010. It was then put in my wardrobe and came out to use ocaasionally for a couple of gigs and then went back in the wardrobe until earlier this year.

In 2016 I have gotten together with some friends to form a new covers band and we have rehearsed at pretty big rehearsal room volume with live drums etc. at an average of 2 rehearsals a month since March.

Today, I started to set my amp up as usual - plugged in and turned on with standby. Took off stanby with all 3 channel gains and volumes at ZERO. 1st channel (Clean) some gain + some volume (uaual position around 2 and a bit....rarely get it to 3, haha!) and it made all the usual signs of working well and giving me a great clean sound.

Turned to the other guitarist for a quick conversation about pics he bought on e-bay and I found my volume dropped!!??!!

I checked leads, connections, another guitar, but my Marshall is not doing what it has been doing. Our other guitarist put his guitar through it and it needed almost full gain and full volume on each channel to get any volume on the output.

I turned ot off and used an amp that the rehearsal studio had available. Effects and leads all good, so the issue is definitely the amp.

Am I experiencing a dead valve, or set of valves, or could it be something more sinister? This is my first valve amp and appreciate that these things are much more sucsceptible to issues and need much more maintenance than their solid state counterparts.

Any advice on this would be much appreciated. I have searched the issue and found that there are some sites with negative thoughts towards the JCM 200 series and the TSL 122 in particular with biasing issues etc., but what I am reading is going over my head a little, but looks quite damning???

Thanks for any help,

Graham

Hello, I've noticed that the firmware update is only available for windows not mac. Is there any alternative way mac users can update? Or will this be an option in the future? 

Many thanks

I've had a DSL40c for a year or two, and it worked fine until a few months ago.  While playing, the sound cut out and there was a slight burning smell.  I replaced all tubes and pre amps and it worked fine in testing, but then did the same thing when I got it home.  Repair guy thought it was a pre amp issue so changed those out again.  It worked fine in testing, and then did the same thing again when we got it home.  This time when we turned it back on, it would work, but sound would go up and down sporatically with some popping and crackling.  Replaced the tubes again, and it worked fine for an hour.  Then the sound cut out, and we noticed it would not switch channels.  After turning it off and letting it cool down, we turned it on again and it worked fine and channels would change.  I'm not sure what to do at this point.  My weekend routine of dropping the amp off and then getting it back (with high-hopes) has gotten old.  The problems have occurred while plugged straight into the guitar, as well as through a pedal board.  Also, the problems have occurred via multiple power sources in different locations (i.e. not always through the same wall socket).  

Thanks for your help

How to?

 I need a real solution and answer as to what's wrong with my code100 amp head! Is there any solution to not hearing sound clear thru headphones..... otherwise I'm sending this back and will try another Code 100 head but if the second amp does not work then I have wasted 1 whole year waiting for this amp and it Still is not resolved..... Marshalls reputation is at stake!!!!!!! Please help me 

Is there a matching 1x12 cab to pair up with the DSL40CR?  Would be nice to have one like the 1922 cab for 2x12 combos.  I am not sure if there is any 1x12 extension cab lines up perfectly with with DSL40CR cab.  The MX112  seems to pair up with the DSL20CR so it doesn't look that is compatible as far a size match.  Just adding to the wish list.

As pointed out in these blogs the Code series locks up during editing and doesn't have an app for Mac users. These issues go back to al least June of this year. When is Marshall going address these issuse other than saying "a solution is coming soon?" I recently purchased a Code 50 but I am not going to hold on to it if Marshall is not going to support it. 

Hey, I recently bought this amp (5 months ago) and it was working very well until a couple of days ago. Yesterday I turned on the amp and it's volume was very low on both channels. I had to put it all on maximum in the classic gain channel (Volume and Gain) to get a decent volume for practicing on my bedroom. I reseated all valves, but the problem continues. I also tested the valves hitting them with a pen, but there was no sound that could indicate a bad valve. What should I do?

Hi, all.

I've got a (not very big) problem with recordnig music via USB. I use only clean sound, typical settings for my guitar equipped with 2x Wilkinson WVC humbuckers are:

preamp - DSL, gain - 2.0 (increasing gain over 2.5 makes sound NOT as clean, as I want it to be), volume - 10, B/M/T - 7/10/5, noise gate - 0.5

power amp - American, presence - 2, resonance - 6

I tried Audacity and Presonus Studio One, and in both cases recording level is about -20dB. Of course I can normalize volume in post processing to let's say -3dB and I still have quite satisfactory quality, but I loose this 17dB of signal/noise ratio.

Any suggestion how to increase USB output level?

I have a code 50 and am trying to update firmware. I have an iPhone X with the Chrome app installed (newest version). I am logged into my Marshall and the gateway app. The gateway app shows I am connected via Bluetooth, but on the my Marshall firmware download page it says I am not connected and my browser doesn’t support download. 

It’s very frustrating, Marshall or any support appreciated.
