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? 

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

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.

Looking at online forums, a lot of people appear to have a hard time getting a decent sound. Here's some tips that work for me, using a strat

1. Treble on 4, for everything. Presence on 1 for clean, 0.5 for dirty. Resolution on 5

2. Bass on 4 for american clean preamp, 6-8 for all others

3. Middle on 2 for clean, 5 for dirty

4. When using the onboard distortion pedal for blues keep the drive low = 1-2. Set amp gain at about 3 or 4

Hope this helps

For the past two years, I've been playing.

I play classical guitar, but I want to play metal, rock, and blues, and I'm looking for my first electric guitar and amp, but I can't decide which one to acquire.

For the past week, I've been watching reviews on YouTube:)

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

Hi

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

What can I do to fix it?

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

Are there instructions on how to bias Origin 50 power tubes? A schematic?

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

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

 I have a CODE 25 that I’m gonna be using to record. The pitch shifter sounds artificial set to an octave down to simulate a bass. I also have a Digitech GNX4. Can a bass be run through the CODE25, or should I use the GNX4’s Whammy effect to do bass?

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.

Hey there! I have just acquired a DSL 401 and am searching for a manual.  Anyone have an idea of where I might find one? Thanks.

Hello,

Yesterday I received my Code 50 amp. I played some hours with it and there is 1 thing that i noticed. I play most of the time at home through a headphone because neighbours, and the presets aswell as some own created sets sound really muffed if I add any Cab. I tried diffent Cabs but for me it sounds way clearer without a cab model.  I was wondering how this is possible? Did i miss something? When I remove the cab from a preset add lower the presence by 2 it sounds so much better

And when playing through the speaker while gigging with friends, will this difference still be there or is a cab model "necessary" when playing through the speaker?

Greetings, Tom

bonjour je me présente christopher , je viens d'acheter un marshall code 50 et je voudrais savoir si quelqu'un peux m'aider car je veux enregistrer le son de mon ampli pour pouvoir mettre mes enregistrements sur une clé usb par la suite et écouter si quelqu'un peux m'aider ce serais cool merci(christopher)

Hello,

I have a problem with connecting a TC Electronics G-System to my JVM 410HJS. The way described in the manual does not work. Preset switching is not possible. The Midi channels have been matched to Ch 1 according to the manual but programming is not working. The JVM doesn't receive messages (no fast blinking). Does the G-System not send useable midi data at all?

Thank you in advance!

Guido

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. 

Hi there!

Do you know a way to use bluetooth connection as audio transmitter on Marshall Code 25?

I have to practice at midnight, so i need to be silent for my neighbours.

Otherwise only solution is to buy a bt transmitter? Any idea?

Thank you all who read this.
