I have the CODE 50. My problem is with the master volume knob. When I set it to ~ 0-0.9 it is very low, but once it gets to ~1.1 it gets immediatelly too loud and there is no way to achieve something in between. Controling the master volume is a real problem cos I can not get a normal (not too loud) volume. You can make the increments between 0-2 a bit more slowly increasing to allow better management of the master volume.
Another thing is the playback volume on both the Gateway app and the line in. When using the Gateway app I have to lower the volume (1-3) and increase the master to a lot more just to balance the backing track and the guitar. I have tried my phone via line-in, my laptop and even connecting it to the output of my Creative SBX. The only thing that works is cranking the volume pass 100% on the PC player if it is supported to get it to be loud enough to play along.
Have you tried adjusting the threshold? and using the volume instead of the master volume?
Unfortunatelly that does not solve the poblem. Changing the volume also changes the sound of the patch... so it is not the desired solution.
I am struggling with the same issue mentioned here. In order to get the Bluetooth or Aux In audio to a reasonable level I have to turn up the master volume but this results in the output of the guitar being excessively loud unless I drop the volume of the patch to a very low level (1.0 - 2.0). Doing this for all patches is awkward especially when the usable range to match to the audio level is so narrow. Is the patch volume a reactive parameter of the model or just an attenuator? If it is a reactive parameter, then using this method may also be compromising the tone of the patch.
I would like to add support to the idea of adding a ratio control that can adjust the balance of the Bluetooth/Aux/USB audio levels relative to the guitar level before hitting the master volume. This is the only problem I am facing with what is overall a great product.
Hi, the issue is not only on the code 50 my 25 is the same, volume knob right down= no sound then as you slowly increase volume very little happens than once it kicks in it far to loud. This is a issue but best of luck trying to get help from tech team as I have had a concern with a hissing noise for about 4 months now and no further forward, I was told the same turn down volume or adjust noise gate which I don't want to do as it alters the patch.
Is there any possibility that this issue gets fixed:
"I have the CODE 50. My problem is with the master volume knob.

Same here for my code 25... It's a little bit disappointing for a practice Amp, to have to fight with master volume between 0.9 and 1.2 to get a decent bed room /living room volume
My Yamaha THR10C has a much more progressive volume (but not has good overdriven sounds...)
I ask my question directly to support by email.
They said that R&D team, is working on it. They also said that the next firmware update should solve this issue, but they didn't said when this update should be released.
Guys are you still alive? You are clearly ignoring us... The first message of this topic was in Oct last year, 8 f***** months ago.
Same issue, Code 50 amp. First the volume is too low, and then suddenly within a 1mm turn of the MASTER knob it gets toooo loud.
And still no FW update from Marshall. This is a kinda big issue and it feels like Marshall is ignoring the issue. Please release a new FW before the summer!
More than one year that your "developpement team" is working on that issue (original post from Oct 2016)...
Come on Marshall do something! Less talks and appologies, more actions!
I guess at this point, we're simply stuck with a bad design decision. The amp sounds good enough I'm willing to live with it and adjusting the patch volume seems to work fine recording with the line out. If there's a real difference in tone, I can't hear it.
We are looking into this and have passed it to R&D
THIS ISSUE IS STILL ACTUAL !!! THE MASTER VOLUME ADJUSTMENT IS NOT LINEAR !!! PLEASE MAKE A FIRMWARE UPDATE TO SOLVE THAT !!!
Did this ever get sorted guys? Had mine delivered 2-3 days ago and the issue is still there on the master volume.
I just want to add my voice to those talking about this issue. I recently purchased the Code 50 and am considering returning it because it's just not usable in a bedroom setting most of the time without headphones. Some of the presets can be adjusted down, but at least a few of the ones I've tried are simply way, way too loud to be usable. With headphones the levels are usable, and the amp sounds really nice, but I don't want to have to wear headphones all the time just to use this at home.
I am super excited to see such a community around these amps, and how programmable they are, but this (seemingly) simple and obvious volume problem is very annoying.
I have exactly the same problem with the Master Volume Poty on my CODE 25 like all the others here.
Please Fix this issue.
Must say I have similar issue with how much powerfull the volume is in lower levels.
The Master indeed after 1-2 is very loud.
Though I have learned that any preset also include some settings of volume level (so I can reduce also the volume and not only the master), I am still get loud output when the volume is around 2 and master around 2.
Bit higher than that, and the bass strings have very much "presence" (which I failed to lowered using any settings). Lower than that, I can here the metalic sound of the guitar strings...as the sound is too low...
The best solution so far is to play with headphones. (now I am looking for good set to match this power...)
I have thoughts about maybe replacing it with something more quite and more fit for home use, but I do like this amp. so I assume I will still think about.
Dear support team, any chance fixing this master volume issue via a firmware update any time soon? Thanks.
Guys you know what, I am reading through this whole discussion about the problem I also have, the master volume knob. I was hoping there will be an answer here or a solution, because I own the amp for 4 years now and I just played it like 10 times and everytime I was pissed of by this volume knob. The sound is great, the amp is great for practicing / playing with the band, but why the f*** is it not able to control the master volume properly?
I will be very happy is Marshall Support will stop to say this bullshit again and again to use the volume knob instead of the master volume.
Do you even understand, what the difference between the volume and master volume is? What these knobs makes with the overal sound?
And are you kidding with the last answer, that the master volume problem is not a fault, but the design of the amplifier?
So if the car manufacturer makes a gas pedal not sensitive as it should be, you will tell him not to use the gas pedal, but to use a brake together with gas?
This is how you treat your customers?
For sure there is an engineer / engineers, designers, etc. in Marshall, who knows how to solve this problem easily.
But this takes some work to do and this cost money, right? So this is the reason, why you don´t want to help your customer?
Honestly I will be very happy if you can take your amp back from me and return me my money, because I just can not use it at home.
The Volume pot is not apart of the firmware, so are R&D team are looking into this.
I can't figure it out if the firmware update released the 10th of Oct is supposed to help or not...
It's still tricky to tune that master volume, but maybe it's a little better.
I'm a user from Korea! I got my Code50 a month ago, and I'm experiencing the exact same issue. Code50 is NOT suitable for bedroom (not even living room) at all due to this volume and master issue. There are only too quiet and too *ucking loud - there's no in-between. Whenever I turn on the amp, my daughters start shouting 'Dad, it's too loud!!'.
If I had known this issue earlier, I would have not purchased this. Please please please fix this issue. Aren't you guys like the best amp manufacturer in the world?? Come on!
From a very disappointed Korean user.
I just unboxed my code 25, and immedialy was faced with this issue with a backing track through bluetooth. For me, the app won't play the song - although I can use iTunes bluetoothed to the code 25 to play, but the volume is so low - I have the same issues with the master and the main volume.
Otherwise great amp, but I always practice with a backing track.
I'll throw my 2 cents in. My code 100's master vol pot would jump volumes all over the place. No sound on 1, then on 2 it would blast you out-- then go quiet on 6 or 7. It was also scratchy despite cleaning it. I messaged marshall and they said try firmware blah blah. I replaced the whole damn board (since you can't get an individual pot) . The part number is M-PCBA-00005 for a Code 100 combo. It works great now. I'm not sure if it's the same board for all models - just email marshall for the correct part number. I ordered it from www.tubesandmore.com for around $76.00 shipped.
Same problem. You have a nice clean tone at about 2 volume then you try a different one and the volume can be heard 2 miles away since the preset has the volume at 7 so you have to use the app to crank it down but then it sounds washed out. Rocksmith 2014 figured out how to make metal guitar sound good at a reasonable volume. WTF? Very disappointed.
Can't judge the GTX100, but my CODEs are my favorite amps of all time for recording direct (analog). This is an issue, and one would hope for better from the company, but it can be worked through by adjusting the volumes using the app. If you like the sound of the amp, keep it and use the app. Otherwise, look for other options.
I have the same problem. Master works ok with headphones but is unusable coming through the speaker.
The same here. I've been using Marshall amps for over 20 years. I started with a 15 watt MG combo and later a JCM 800 and a DSL 100. When the CODE series came out I switched and bought a CODE 100H with 2x12 box and sold my old amps.
How could I be so stupid. CODE 100 has been standing in a corner for years now, slowly gathering dust. It is not possible to use the amp outside of clubs or stadiums.
I have always found Marshall to be a customer friendly and solid company. Any problems with my JCM or DSL were fixed promptly by Marshall. Well, there were hardly any.
But with the CODE series, I feel ripped off and screwed. It's March 2022 and the problem with the master volume should be solved by turning down the preset volumes?
Well, let me see. The CODE is a digital modeling amp. This means that a virtual tube amp is operated in a kind of soundproof room and the volume is reduced to a tolerable level by the master volume.
So the volume pot is only there to regulate the output stage of the simulated amp. So when I turn this down, I change the power amp setting of the virtual amp. This makes the preset quieter, but changes the sound.
The same happens with a real plexi, for example. So that can't be the solution.
So it's like "Marshall CODE 50" already wrote. There is a cost involved and you would have to recall and repair every CODE amp ever sold.
I cannot sell my CODE 100 because the problem is known and selling it will probably result in a high financial loss.
I use a combo from another company, not as good in terms of sound as Marshall, I'll admit, but usable at home.
My daughter is starting to learn electric guitar and I certainly won't buy her a Marshall.
Thanks Marshall, it was nice while it lasted.
Hey guys again,
you know what? I was somehow able to overcome this problem by this solution.
First I was trying to switch the original 50W speaker to the 30W speaker from my VOX AD30-VT. It did not help at all. The CODE was still too loud.
So, after a lot of research, I bought the Monacor AT-52H Mono Bulit-in 50W level control for speakers. Posting the link below.
I bought it from the german company Conrad - I´m sure for example Sven Krebs will be familiar with this company since he is from Germany. But I´m sure there will be lot of distributors of Monacor company all over the world.
Anyway, I disconnect the cables from the internal speaker and installed between the amplifier output and the speaker this controller.
And voila? I am now able to control the output power to the speaker, so I found a good spot on the Monacor regulator and I can finally use the Master Volume as it should be.
The link is here:
Monacor company link:
I know it´s a DIY solution but I was only a small step to throw the CODE out.
But I was trying my best and maybe, and I will be very happy about that, this could help someone else.
Not sure, if there is some kind of regulator for 100W ( I have the 50W CODE version).
Any questions, please ask here, I´ll try to help :-).
I've just bought a CODE 50. I wish I had known before! =[
I've noticed the problem, but I thought it was because I've just purchased a "too loud" amp not designed for homes. Then I've tried a Boss Katana 50 in a house friend and then I realized it was a design problem... How Marshall didn't notice this before!? Come on, obviously this is an amp targeted at home enthusiast players who are looking for a versatile product. It's a shame. I'll try to return it and buy a different one, but they're gonna rip me off with the shipping costs.. well, thanks, Marshall. I thought you were a premium label
