Hi. I have a JMD1 50 COMBO and i'll swap the original speaker that is 16 Ohm. Can i use a 8 Ohm speaker instead ? The back of it we have 1 slot for 16 ohm and other two for 8 Ohms. Can i change the original ohms? Thanks a lot.

Here are a few things I would suggest as improvements to the Marshall Code series. I have a 25 so some things may be specific to that amp. I have stuck to things that could be improved only by software or firmware as these are improvements everyone can have simply by updating the firmware rather than modifying the amp itself.

1. Reduced power mode to switch between full power and lower power mode. This would fix the volume control issue everyone complains about.  Maybe this could be a global setting in the firmware ?

2. USB audio Volume level setting (e.g.  -3dB, 0dB, +3dB etc). This could also be a global setting in the firmware ?

2. Normalise the volumes of the models, some are way too hot (British class A power-amp), some are way too low (Natural pre-amp). I beleive this is the reason why some models have strange low frequency distortion (50s British, OD DSL).

3. Show the configuration of the Cab models, not everyone is a Marshall fanboy and I have no idea what cab a "1960X". even if it was displayed as "1960X (4x12)" I would at least know what the configuration of cab the model is.

4. Fix the spring and hall reverbs, they sound very cheap, like the "echo" you would get on a cheap karaoke machine, certainly nothing like a spring reverb.

5. For god's sake release an official desktop editor!!! with the option to save/restore/edit patches.

6. A sync button to sync the amp presets with your gateway. It you want to rearage the patches online in gateway, you have to manually save all the patches one at a time to the amp using the phone app. So if you add a new patch at position 0, you have to manually save all 100 patches one at a time in order to match your gateway sounds!

 7. Fix the tuner, it is pretty bad on both the amp and the app. It's slow to respond and not very accurate (at least thats what its like on mine). Ive no idea how well it works on the foot controller.

8. If possible add a Fuzz pedal model, even at the expense of removing another model (I wouldnt miss the pretty poor Acoustic simulator for instance).

These are just some suggestions that I feel would make the amp just a little bit better, but in general I'm having a lot of fun with this little amp, and love the sounds and features it has. It is way better sounding than some of the negative reviews online would suggest.

Maybe other people can suggest firmware updates too?

I have the following problem with my Marshall Stanmore (I) Bluetooth speaker:

Whenever I am wirelessly connected, the Bluetooth connection drops after 20 minutes — while playing music!

The surprising thing is that it not just happens randomly after 15 to 45 minutes — no, it happens suspiciously regularly after 20 minutes. I went and tested this with my laptop (4 times) and my phone (3 times) by writing down the start and stopping times, and the Bluetooth connection got interrupted (the music stopped) after 20 minutes each time. 7 times in a row. No exception.

• Yes, I have removed the speaker from all devices, then re-repaired them. Multiple times.

• Yes, the problem exists with all my devices that can send sound via Bluetooth (laptop, phone, desktop,). Those same devices have no problem to stream music to my Sony sound system or portable Bluetooth speakers. The problem only exists with the Stanmore.

• No, the Stanmore is not near a wifi router, a micro wave, a DECT phone or close to other Bluetooth devices. All of my other Bluetooth devices work perfectly fine. During my tests, the speaker and the Bluetooth source were about half a meter/two feet apart.

• Yes, I have had the Stanmore disconnected from power for an hour. Even a few days, actually.

• Yes, sound works perfectly fine via the wired connection (INPUT 1) and it doesn't stop after 20 minutes. 

• Yes, the "STANDBY MODE" switch on the back  is set to "STANDARD". (But surely no Bluetooth speaker would ever go into standby mode WHILE playing music anyways, right?)

• No, I am out unfortunately of warranty. The speaker looks great and hasn't been used that much. I also find that it financially doesn't make much sense to spend 130€ (max.) on a Marshall OOW repair.

• No, the Stanmore I is not compatible with the Marshall Bluetooth app, and there is no way for me to update the firmware (as far as I know).

• Yes, I can absolutely open up the speaker and post pictures of specific components, if someone has a clue about what capacitors or chips to look out for.

Additional info on the issue:
I experience no problems connecting via Bluetooth, from any device. I can start playing music — but after 20 minutes, the music will automatically stop. If I am streaming from Spotify for example, the player will just pause. The Stanmore stays powered, and the red BLUETOOTH light on the Stanmore is still on, but it appears a little dimmer than normally. I have found that pressing the SOURCE/WAKE button once usually wakes up the Bluetooth connection again, and then after a while, I can resume music by un-pausing on the laptop or phone. 

Thoughts? Ideas?
The fact that this happens after a very precise operating time, sure sounds a lot like it could be standby-related. But the Stanmore is not set to POWERSAVER mode. And even if it was, it would only enter standby mode after a certain time if it wasn't playing anything. A speaker that goes into standby mode every 20 minutes WHILE playing music ... that would be ridiculous! And yet, that is exactly what I am dealing with.
Any ideas or clues for what to try or look out for?

As title says I have no output to the speaker cab. All I hear is a very quiet fizz/hum. Output to headphones is fine. Only arrived today and will be going back Monday unless I can resolve this. Code 2x12 cab seems fine and tried three different speaker leads. Gutted as I was so looking forward to getting a full weekend on this before going back to work.

Hi i have a set of combined issues with my Code 50 with the 4 button footswitch

First of, love the products!

But my issue with it is major! I cannot set any preset on my footswitch, It seems so easy on the tutorials but mine just keeps on switching back to the preset that already was on the button (1,2 or 3). I do as followed. I chose the preset i want on ex.button 1, so i hold the "store/exit" button for 2 seconds and then i push the 1 button on the footswitch. But it only changes back to the preset it WAS. So no changes. When i HOLD the "Store/Exit" button for too long (3a4 sec) then it says "stored" and then no sounds comes out of the amp anymore, i can push the REV and AMP buttons and the LED light up. But no sound! The footswitch also then doesnt butch. I have to restart the AMP to get it to work again.

I tried to update the firmware but it already was up-to-date so i reinstalled the latest firmware again. I also tried to reset the AMP back to the factory reset but the problem still exists.

Please help,

Hi. I have a marshall jcm 800 bass series head with serial V20551 and two marshall 1550 speakers with serial number 2003 and 2005.

Can anyone help me with some more info on this items please.

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

Does anyone know if these are still supported by Marshall and if they are discontinued as I've seen on  a retailer site here in the UK? I was looking at buying one but may wait for a replacement model.

Thank you.

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. 

Hello,

I added presets that I would like to add to my Code 50. They appear on the bottom of My Gateway, but I am unable to drag them into my 100 presets. Even clicking the amp icon to demo the preset does't work. I am using Chrome and have my computer connected via USB to my amp (status is Code: Connected).

Also, the 100 presets currently in My Gateway are in a different order than my presets on the amp. 

I have watched the turorials but it doesn't seem to be working. If you could let me know how to add the selected presets from My Library to my presets on the amp that would be great. 

I've got an Origin 5C, about 6 months old.  Has worked fine and is a fun little amp.  But last night I had my first issue.
Got the rig set up, with front-end fx, and also some fx in the loop. Warmed it up, then played a few bars in low power. All worked fine, so I switched to full power, and stepped away for a few minutes to let it warm up some more.
When I came back, it was still powered on (light and mild hum), but the footswitch was dead and there was zero volume. Not even cable crackle when plugging and unplugging the guitar.
I messed around with all the connections. Pulled everything and plugged in directly (also checked the instrument cable). So, guitar > cable > amp. Still no volume, and just a slight hum (very slight; it wasn't ampliyfing anything, so this was just circuit hum).
I dissambled the the thing, to check tubes and connections. Everything looked grand.
Reassembled it, and it worked fine. Played for a good 10 or 15 minutes at medium volume, and it was a charm.
But then the volume started dropping. Would come in and out. Then it dropped completely, and the footswitch went dark again.
I tried connecting an external preamp into the return (with a dummy plug in the send), but no luck. Footswitch was still dark.
Hum but no volume.
Haven't tried it yet today, but I'm expecting the same behaviour. My assumption is that there is something that goes sideways when the temperature gets up.
So, two questions:
1 - Is this a power tube issue? I haven't noticed any other problems or symptoms of bad tubes. And, like I said, it's 6 months old. Never gigged, but played loud fairly often.
2 - What's up with the footswitch? I can't find any schematics of the Origin series, and I don't care to go tracing. So, I'm not sure exactly where the FS fits into the circuit. I was wondering if that symptom might help to diagnose.
Anyway, a great little amp, but it's acting up!
Has anybody had or heard of this issue?
Thanks, friends

Hi. Can I use the Code 50 whitout presets? I have a MXR Zakk Wylde overdrive and a Boss Chorus. I would to use them but also whitout the presets.

 Hi. I want to ask if Marshall Woburn II is any good at low volumes. Do I need something dedicated for playing music/movies at low volumes ?

It's always been very hit and miss but the Bluetooth connection of the gateway app to my Code 25 literally never works. Why aren't Marshall doing anything to fix this? Surely can't be difficult. 

How do I sync my CODE 50 amp to my android phone? I updated presets on the phone and PC but they do not carry over to the amp. All help appreciated.

For a couple of years I have owned a Code25 and a Code100. And I'm very happy.

I understand the criticism of Marshall's patches, but for me it's no problem. I have simply never used any of them. It was enough with one try and I realized that I have to find the right sound myself.

Only once have I found a patch that fits my guitars directly. It was SCJM800 SLF, but in that patch everything goes to eleven.

It is far as I can see some extremely important things to think about. 

First of all, the settings differ a lot between the guitars, I guess because it is a digital amplifier. A perfect setting for a Les Paul can be useless for a Stratocaster etc.

I myself have played on the amps with a Les Paul, a Stratocaster and a Telecaster. And each guitar requires its own settings. This is not strange, a consequence of how the amplifier is designed. 

Another crucial thing is the height of the microphones. There you have to test yourself to get a good sound, especially single coil may require adjustment of the microphone height. Height adjustment gives enormously much more effect than on a tube amplifier.

In general, I can say that my sounds are closer to the original with both precence and resonance quite loud. In addition, the Compressor helps quite well. 

In short: Since Code is a digital amplifier, it obviously works completely differently than a tube amplifier. It is not possible to fix good sound for a Gibson and then think that it will automatically sound the same on a Fender.

All this applies to JTM45, Plexi, JCM800 and Classic American. I have not tested the rest so carefully.

Can you tell me if it is possible to use the expression pedal at the F / C input as a midi?
Amplifier marshal code 25. If yes, what kind of pedal model?

Surprised how quiet these forums are, in particular about the Code's?

I would have expected there would be several hints and tips and lots of new patches uploaded every day.

Has everyone dumped thier Code's by now?
