I get no guitar through the headphones. What must I do to get the audio from my guitar to the headphones? I would like to use this as a line signal to another amp.
I do get audio out from my phone to the headphones when Bluetooth is connected. When Bluetooth is connected, whatever is playing on the phone will be heard through the headphones. So, I know the headphones AND the headphone jack both work.
Cable plugged in to both computer and Code 50. Display shows 'Ready for Update' - but neither the browser or Desktop Utility will connect.
Rebooted everything and tried from laptop. Same results. What's wrong?
Why can we not update via bluetooth connection rather than USB cable?
I have been using my Marshall code 25 since last yr and noticed that when the amp is plugged and NOT turned on. There is an electric current at the end of the cable. It only dissapears when I turn on the AMP. The electric current runs until the guitar when its plugged. I have tried the cable on other amps and it was fine.
Has anyone experiences this? or is this normal?
Appreciate the response.
I want to exchange valves in my Origin 20h, ordered some from Tube Amp Doctor. After I exchange them do I have to rebias it? Is there a manual for rebiasing? I wasn't able to find anything which would give me even slight bit of a hint about it .
Does anyone have a good heavy Robin Trower (like Bridge of sighs stuff early early stuff) and please don't say HENDRIX......thanks D.Wells
I have a code100H with a 2x12 ext. cabinet,can I plug my ovation in I would like a clean sound but maybe a little chorus?
do I need to have a speaker connected to thecode 100 if I am using headphones?
Does anyone have a Steve Lukather sound dialed in?
I think I might have tossed out my USB cable by accident! I cannot find any place to order a replacement one, not even on Marshall's web site.
Hey Marshall, you ahve my email, why not tell me how much and where to pay so I can get a replacement and update my Amp!!!!
after correctly updating the CODE AMP and the Gateway, the connection is still wrong, I had hope with the last update but it has not helped me at all.
he version of android that I use is ANDROID 9, with the phone Galaxy J6 + ..... I do not understand where the problem may be.
I would appreciate Marshall's help in correcting this problem, they have already contacted me for a long time but the guidelines were erroneous from the beginning.
Thanks for all.
Can I save downloaded user presets to my footswitch and how???
Using the Code 50
Dear Marshall Team,
It took some time, almost a year, but finally we got the long awaited update of the firmware to fix the painful Bluetooth issue on CODEs. I installed it a few days ago (which was a bit of an issue as reported in another of my posts but finally succeeded) and now CODE does what it is supposed to do. BT comes on and connects as it should every time I turn on the amp and start Gateway on my Ipad/Iphone.
I'm very happy that you could fix the problem and I encourage all brothers and sisters in pain to upgrade the firmware asap if they haven't done already.
In the light of this fix I think we, the community, may also forgive you that for months you told us that it is not a firmware issue ;-)
So far I also think that the BT connection is more stable than it used to be.
Now I can enjoy again my little CODE 25.
Thanks, Alex F.
Running V1.43 firmware.
I have followed all instructions and can not get the iPad 6 to connect in Gateway app.
It, however "pairs" just fine Bluetooth wise on the iPad 6!
AND Gateway works well on my iPhone 5, switches presets and everything.
So I know I am doing this right and the Marshall code 100 Head is responding via Bluetooth (with my iPhone 5) but NOT with the iPad 6.
Edited: Its the damnedest thing. I removed and reinstalled the app on my iPad 6 at least 8 times with the same results.
Then I reinstalled and paired the "9th" time, and it worked!!!!
I can turn the 100 Code head amp off, and back on and it still connects.
I'm glad it works now, but I dunno what I did differently.
I have a bunch of Marshall amps and recently added a Code 100H to my collection.
I'd like to connect it to a JMD1 102, in order to use it as a valve power amp and cab for the Code as a preamp. I usually do it on my other amps by connecting the send from the "preamp" to the return of the "power amp", but in this case it didn't work, the only way to get some sound from it was connecting the headphones output to the input of the JMD1, but that's not what I expect once I have another preamp in the chain. Did anyone tried something similar?
my amp says that bluetooth pairing has been enabled but i dont know how to restore it
I cannot install the new Firmware on my Code 25.
Amp Display Shows „Ready“
Marshall Firmware Update Utility says:
„the code Firmware is being updated - please wait“
on the bottom it says
Updating MCU Firmware...
but nothing - nothing happens. No Firmware Update....
anybody having the same problem? Please help!
Best Rgds, Alex
Got it to work by using Microsoft Edge Browser and the the Firmware Update tool. (Windows 10)
Google Chrome did not work, and update tool in Coogle Chrome also didn't work.
Anyway at the end iI could update and I'm happy now because the Bluetooth Problem is really fixed.
Can't seem to connect the app with my amp on my Huawei phone. It is detecting the amp, but won't connect with the amp. Just stopped working today.
Having problems with the desktop software too, I downloaded the update and now the shortcut has disapearred. It keeps showing Marshall Firware Update Utility only, even though it says I have the latest software.
Hi, since the latest update of the Gateaway app a couple of days ago it has stopped working entirely on my phone (Huwawei P20) and now I can't use it in any way, shape or form to control my Code 50.
When I open the app, at first I see a flicker of how it should look (or used to) and then the screen changes immediately to almost blank with a couple of small coloured areas on and nothing else, nothing to click on, no words or other symbols.
Please can you let me know when a fix will be available as I believe lots of other users too are having the same problem since this latest update went out.
I just bought a DSL20CR and I LOVE IT!!! I've noticed that it pops pretty loud when footswitching from ultra gain to classic gain and I HATE IT!!! Is there anything I can I do about it? I LOVE the way the amp sounds....But that popping sucks
Currently my JVM410HJS squeals periodically. Initially this would only happen occasionally and I was still able to gig with it, but now it has become to frequent to use. It will do this even if unplugged from a guitar and will do it no matter which channel it is on. Channel switching does not stop it. I am not sure where to start. Am going to change out the tubes and reset the MIDI switch, but otherwise will have to travel a good distance to find a qualified tech. Anyone else ever had this issue?
