I got my CODE all set up with tones that I thought were going to work well.  Used it at practice for the first time yesterday and found out that everything seemed boomy.  I didn't have time to experiment too much, but any suggestions on what to adjust to try to get rid of the boominess?  If it matters, I have the volume set pretty low on the patch and had the master volume up pretty high.  I don't use any real high gain stuff - just your basic dirty/crunch types of tones.  Good example is the factory default Plexi.  Thanks in advance!

I was able to connect only once. What am I doing wrong? Help!

Can not seem to piar phone with amp, push rev and power at same time nothing happens, can you help?

I own the Stanmore Marshall blutooth speaker...and absolutely LOVE IT!!! (Bose.....pfffftsh)

I am new to the Marshall site but wondering if the smartphone controls pertain to the model I have?

Thanks in advance.

is there a driver for the code amp so i can use it with my DAW?

Given that the code head is 4ohm; is there any danger in running it into an 8ohm cab in the long run?  I understand it will halve my output power, but I'm more concerned with long term damage to the head. 

Thanks

When will there be a firmwear upgrade to correct the bluetooth connection problems ? I have followed all the instructions on the forum and still only occasionaly manage to get a connection before it disconnects or freezes at rehearsals which is very frustrating to say the least.

Using an Iphone 6s and the latest firmwear version with Code 25

Come on Marshall this is becoming a big issue 

Hi Marshall, 

I just got the code 50 and i'm not being able to download my songs from Itunes from a iphone 7 even the ones i downloaded from the cloud!

Do I have to make the firmwire uptade ?

Thank you !!!

My JCM2000 TSL100 will power up and play fully....after a while 30 mins or so....it will fade out to no sound....or weak sound....power it down then up again ...it will play full for another period....had the smae problem before and took to amp guy...it worked perfectly for him...maybe he didn't play it long enough...so I said for him to replace all tubes anyway... it is now doing it again after maybe 50 hours of play....any thoughts or just preplace tubes again....if its a tube is it likely to work for a period of time after its powered down then back up?

I just bought a new phone and i cannot download Gateway app for Huawei :( ?????????

Any ideas??

Hello,

I own a YJM Model head. It has an issue with the digital board processing (part # MD55-66-00-1SS3) and i just can´t reach Marshall´s support to get this part.   I´ve sent an email but had no response. By phone they will never call me back as i live overseas...

I live in Brazil and don´t know if there is a Marshall Support around.

Please, help me out.

Thanks

Marcio

Is there any chance to rectify the way the master volume pot on the CODE 50 behaves via a firmware update? Or is it a malfuncion on my device?

From 0 to 1 there's, well, nothing. No sound. Above that, there's about two millimeters of neighbour friendly bedroom level followed by an abrupt kick in the guts.

Thanks in advance.

Hi all, 

Just a basic question. Wondering if the fx loop in the back of my amp was Line Level. Is this universally true? Are all fx loops line level?

Thanks.

I bought Marshall CODE 25, connect USB cabel to PC, install ASIO4ALL driver, run Nuendo 4.3, driver Control panel show MONO IN - STEREO OUT, record fine but there is no stereo streaming from PC to headphones, only MONO. Everything is OK in Nuendo Audio Control Panel. I try with Media Player with MP3 files, same problem, only MONO. Try Abletone Live - same problem.

Is this normal for this amp, or mailfunction?

Thanks

One of my power valves is redplating, and prior to that there was a really loud sound coming through the sneaker that sounded like an electrical surge. Is it just a new valve required or something else. At first there was a noticable hum,  then I went to plug in my guitar and as soon as I picked up the cable, it made that loud bzzzzzt sound and I shut it off. I then tried it again and noticed the redplating.  

I cannot get connect to my code 25 amp via bluetooth.  I have followed reset instructions on the forums here, no luck.  I have an iphone 6.  My bluetooth sees the code on my phone but will not connect to it.  Sent message two weeks ago to Korg/Marshall.  No answer.  Time to find a new amp.  Hi Fender how's it going?

Hi&Hallo for everybody !
I'm looking for setup to play that kind of sound (or clouse enough):

I just bought this amp yesterday after flirting with a Blackstar HT20 and realising I wanted a Marshall again. Well, starting to wish I hadn't bothered.

Like so many others, I can get my phone (Samsung Galaxy S5) to connect to the bluetooth and actually play music through the amp. BUt Gateway will not find the amp within the menu. I've tried all the uninstalling Gateway, reinstalling, updating the amp's firmware - even tried using my daughter's Samsung S4-mini which again, connected to the audio but will NOT FIND THE AMP!

I have a Samsung Galaxy Tab 4 which is a good wee tablet but apparently isn't compatible with Gateway.

Seriously. So I have 3 different devices and not one of them can connect to my new amp.  Clearly this is a fault with the amp itself since the same thing happens with two different phones.

Please don't tell me to go through that long list of uninstalling, reinstalling, removing the bluetooth device and reconnecting etc etc. I've been doing all that since I got the damn amp yesterday afternoon. 24 hours later and none of it has worked.

Is it at all possible this is going to be addressed SOON in either a Firmware or Gateway update? Clearly, if the amp is faulty I will need to return it soon to get my money back but, honestly, I'm loving the sounds I'm geting with the presets, I just want to edit them rather than all the hassle of returning the amp to the shop!

I saw a review on the Google Play Store for the Gateway app from a guy in June 2016 - that's 7 months ago - and he was having the exact same issue. So if it's not been addressed in all that time and Marshall are still sending out these faulty amps, what hope for a fix? Please tell me there is one!
