I am wondering if anyone has a preset that will work for using an external effects pedal into my Code 50? I only want to run the external effects (distortion, reverb, delay) and nothing fromthe amp itself. What I am seeing is that even with all effects (amps, modeling, etc.) turned off on the Code my pedal into it sounds like garbage. Very muffled, bassy, and muddy. I have the EQ on the amp set so that the bass is all the way down and mid/tebble are all the way up and it still sounds terrible. I don't want to have to edit and mess with every patch on my old Zoom GFX8. The pedal doesn't sound like this into my old 40 Watt Fender bassman.

Any advice on setting up the Code to sound good with external effects would be greatly appreciated.

Hi

No response when I tirn on mu Stanmore speaker. No lights, no sound, nothing. 

What can I do to fix it?

Hi Guys,

Hi, I recently bought a code 50,, but about 6 times now, while holding the save button to quick save a preset, after  saving there is no sound from the amp, and I cannot change presets, or any other parameter. Turning the amp off ,then back on, and it starts working again. This is using the controls on the amp, not the gateway app. I checked the firmware about a week ago, and the program says I have the latest firmware.

I can play music through Bluetooth on my Code when using iTunes on my phone, but get nothing when using the playback tab in the Gateway app. Where am I going wrong, folks? 

 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 

I bought a CODE 25 amp and I can’t connect with any computer, I have tried with 2 different cabes and some differente OS: Windows 7, 10 and macSierra. I was thinking to update the firmware but, I can do that because the amp is unable to be recoginized by a computer!

It`s really frustrating!

Jesus, every pedal I hook up to this brick hums so badly. I've changed cables, batteries, outlets, ect. to no avail. I can hook straight in and it sounds great, the moment I try to add my looper or wah pedal it hums so badly. What am I missing here?!?! TIA

Not a lot honestly. I've had a 50 watt Marshall DSL head for about 6 years now, and it's been wonderful.

The thing is, Marshalls do the Marshall sound very well. But people do not have the space to make the Marshall come alive. Even 50 watts is way too loud to cut loose and open it up to a really nice saturated volume. To keep up with the br00tal metalz times, Marshall has been increasing the preamp gain stages. I have 4 preamp tubes in my amp, and it has way too much gain on tap. Preamp gain will always sound fizzy and harsh compared to poweramp gain, and Marshalls produce way too much volume to open up the poweramp to a nice tonal level, especially in the era of excellent PA systems and great microphones

I think that a lot of folks throw money at the problem, buying independently built amps made with period correct caps and resistors, PTP wiring, etc. But the differences are marginal at best when comparing two identical circuits (mathematically speaking) build with the types of parts used at Marshall vs. NOS stuff by indie builders. I honestly think half of the appeal is placebo effect. Players fool themselves into thinking their indie build JCM800 copy sounds sooooooo much better than a newly made JCM800 from Marshall. They're the same, any difference will come down to the speakers, microphones, PAs, and guitars used.

How do I restore my Code amp footswitch to its original settings so I can just scroll through my amps presets?

HI just got  a new (3 days old) JVM 205C and played it a couple of times then when I went to turn it on again it will not make a sound!

It starts and all the tubes light up but when you turn off the standby nothing happens and no sound at all comes out, not a click as if the standby swith is doing nothing.

I did read the manual about the FX loop button muting the amp without effects plugged in but I have tried everything I can think of so far, guitars, leads other power sockets but no go!

Anybody have any ideas???

Thanks

Mark

I am running Windows 10 on a compatible laptop and get an error message when I try to run the Marshall update utility software. It occurs after a "verifying application requirements" window pops up. The error starts with "An unexpected error just occurred. Cannot create instance of main window"?

Any advice?

Steve

Dear all.

In my code 50 fw 1.41, when I play, I  hear noises eg preset 02,03.04,06,07 ... 93. Is it similar to you or do you have a clear sound (no noise)? My guitar Gibson les paul tribiute 2017 and I use cable Fender FG10.

The best Regards

Jaca

I can send a sample to interested persons

Greetings, 

I recieved my Code 100H this week.

Firmware:

(FYI) I attempted the update with a MacBook Pro with USB-C, High Sierra 10.13.1, Chrome Browser. I was able to connect to the Code but the unit would not update. It was stalled on the progress bar on the unit at 0% and on the browser. 

(FYI) I attempted the update on a Windows machine and was successful using the update utility and with Chrome Browser. The Code unit shows updating to 1.4.1 but the boot screen shows 1.11?

Bluetooth:

The Code 100H will not connect to any Bluetooth device I have. Windows, Mac, iPhone, or iPad. It does not even show up as a device and never has even out of the box. I am convienced it does not work. Is there a master reset button combo for the unit? I am out of ideas concerning the Bluetooth. It seems like I am not the only one having issues with the Bluetooth. If this can't work consistently I am considering returning the unit. Even the simplest device can connect with Bluetooth and hold a connection. My Code 100H won't even show up as a device to connect to. Please advise. 

Hey Marshall,

I visited the dealer recently and tried another CODE 25 amp in the shop with the same latest FW version.
The same bluetooth behavior was observed (as described in many threads here, for example this ).
If you insist that it's a HW problem - please make an official statement that CODE 25 amps with serial numbers XX-XX have faulty Bluetooth Modules and you would like to recall/replace it. I think you can easily check your production and make a quality check on this case.

I think there are only few ways forward:

-  a FW update with a fix, promised a long time ago. Is it really so hard to rollback a piece of code, revert some changes from the latest FW update? 

- official recall, so that we just return it and get a 100% working unit instead.

- make the firmware code open source, so that we could fix it ourselves and make further improvements.

Regards,
Ilya

Hello!

Have a 6100LM three channel head. The footswitch that comes with the amp is huge - it takes up a large amount of space of my pedal board and I only really use it 3-4 times during a set (swapping from crunch to clean and back, never really use the lead channel). Does anyone know of a smaller replacement footswitch that could do the job? I only really need "channel up/down". I know the head has midi switching but this kind of thing is not my strong point......

Appreciate any help I can get!
Best

Andy

Has anyone else been having problems finding the amp on bluetooth? Some days my iphone 6 can find it other days it can't. I feel like marshall abandoned the code amps. Does anyone know if they will be releasing a firmware update soon?

Hi,  I have spent hours  trying to develop a clean sound and I am beginning to think it's not possible with this amp.  It is way too bright, or high toned...  It's like the guitar's B string is way louder than the other strings..  I have tried 2 stratocasters, and my alvarez acoustic and they all sound horrible.  These guitars sound fine on other amps.  I have even turned off all of the effects and I can still hear that high ringing noise, so it looks like the problem is not something I can adjust away...   Has anyone else experienced this?  Hopefully I am missing something simple, because I love the idea of the amp and interface.

I really need the above to repair my Marshall MG30CFX  guitar amp. Can the forumers point me to the right place to download it?

After struggling for an hour with instructions in the User Manual and online Support, here's how I was able to pair my Monitor Bluetooth Headphones with a second source:

1) Turn off Bluetooth on the existing/first source.
2) Power off Monitor headphones.
3) Press and hold the Power button for ~10 seconds (in other words, keep holding after the initial "power on" tone) until you hear a second tone.  The LED on the headphone will blink with a sapphire color.
4) Discover the Monitor headphones on the second source and connect.

I love my headphones, but the User Manual and on-line help are deficient on this topic.
