My new CODE-100 2x12 has a prominent digital fizz noise it also crackles, very unpleasant specially when you use tremolo, chorus, delays.
Very noticeable on the decay of the notes, decay of notes crackles.
When you play the low E string unfretted it makes a buzzing noise, this is difficult to forgive in any amp.
Are you guys at Marshall aware of this? should I return the amp?
Regarding your CODE100 we are sorry to hear that you are experiencing a problem with your new amplifier, the amplfier is designed and constructed in our factory with good quality and reliable components. We are always striving for the best quality and reliabilty on all our units so your feedback will be passed on and we can only regret you feel so strongly that you wish to sell your unit.
We would recomend that you take it back to your dealer so an engineer can service the amplfifer for you and find the source of the noise you are experiencing.
The CODE should not be making any fizz or crackle noise. Have you tried using a different cable? Failing that i would return to your dealer for an exchange or refund.
I'm finding this same issue, digital artifacts distortion under high gain - enough to where it hurts. I can hear strange clicks and fret noise.
I am going to try using a Tube Screamer into a clean amp setting, and see if this solves it. I will respond when I know more.
Hi Everyone, The Code 100's hum/buzz/noise is the result of this cheep transformer. The noise is NOT coming from the speakers of the unit. It is electrical noise coming from the components inside of the amp. A noise gate WILL NOT FIX the issue!
I just played a show yesterday with this amp and I was embarrassed when people who don't have a clue about guitar or playing music come up to me to tell me that my amp is making a funny noise.
I am thinking of selling my amp and trying another. I was thinking of trying the new Marshall MG102GFX 100-Watt 2x12 Combo.
I created a youtube video to share. Please watch and listen with headphones to really hear and understand what I'm talking about here. Lets all compare notes. Comment here if you are experiencing the same high pitched noise/buzz issue...

Hey Carlos... ok so, I have the same issue, the good folks at Marshall have been working with me to try to resolve this one. There's bad and some good news here. I have tested it to the ends of the galaxy, and conclude this is an inherrant feature of the CODE amp.
For me, I cannot get rid of the whine noise completely, it's there, at ZERO volume, and doesn't increase with volume until you add some reverb in the loop. It seems adding modulation to the loop starts to amplify the annoying signal, which is then boosted by the volume control.
BUT i did discover that if you add a noise suppressor (we use NS2s) at the first point in the loop, it acts a noise gate, and is enough to strangle the inherrant whine going through the loop and then amped. This does NOT stop the whine at zero levels, but it does do a lot to cut it down, and, prevents the whine from corrupting modulation going through the loop itself, which was my biggest beef. To cut the whine out completely, we add a weakly set noise supressor (another NS2) on the mic, and this allows us to mic it up without issue.
The CODE is a fabulous piece of kit, coupling up your pedalboard with the inbuilt modelling gives you a hell of a lot of sounds to play with. Shame the whining puts a dampener on the otherwise excellent amp.
I have ran this past the good folks at Marshall directly, and extensively tested. Folks aren't going mad I promise. I have asked Marshall as an ER (enhancement request) to examine the circuit and eliminate this rogue interferrence. It shouldn't be up to the players to compensate with NS2s, but, compensating with these does allow the amp to function.
Not sure if it helps, but would be inetrested to hear if this does indeed help.
Simple fix. Lower volume to 4.2 or less, master no higher than 10 o'clock. Bingo..no more crackle.
I'm having the same issue aswell on the Code 100... even when the the volume is on 0 it makes pops/crackles annoyng sounds, tried several powercords several wall plugs, diferent houses wall plugs... you name it... I'm very disappointed... probably will be my last Marshall
hey so the buzzing and crackling sound goes (almost) away when you pair the 100head with your mobile device.
the problem is with the bluebooth hardware/software.
Hi Carlos, cheers for the reply back. OK sounds like yours is slightly different to mine. My one does not make pops or crackles, and is not affected by connecting bluetooth. I specifically use an android tablet for the app controls, it works really well.
Do what I did, contact marshall support. They are super helpful and will try to help. Marshall sent me a CODE straight off the latest production batch, and left it with me for quite some time to test it before giving the thumbs up.
Just for reference, my amp did not pop or crackle, it just had a droning whine, which was exasperated by adding modulation into the loop. I needed the loop as the code has some great drives which you ideally need before modulation, hence it bugged the hell out of me. Someone linked the exact noise up in the thread.
Anyway I'm waffling... before giving up on the Marshall, give customer service a call or email, I know they'll be happy to assist. The folks I dealt with were excellent.
Cheers, and best of luck, keep everyone posted.
I have the same problem! Its clear to me that there is no fix for this known today. Any posibilitie that Marshall fix this by firmware?
POSSIBLE SOLUTION: Disconnect Bluetooth PCB module from the system.
CASE: Randomly my Amp software started crashing and freezing making bad noises coming from the rev and delay digital modules, if I disable this options the amp stopped the weird noises but also effects, so this is not the best option. For this I looked with an osciloscope all signals and power lines, and Power line shows a lot of noise, also when bluetooth worked the noise increased a lot, yesterday I disconnected the bluetooth module power cable and now seems to be working withouth noises and crashes.
If I get something new I share here.
