Hello,

Last December I bought an MGFX30 amp. After a few months of use I realized that the volume knob does not correctly work. On either of the 4 channels if I turn the volume fully down, and then turn it up, the volume becomes faint and distant. If I then switch to any other channel without touching the volume knob, the volume of the other channel is correct, loud and clear. 

I returned the amp to the seller and it got replaced today to a brand new one. When I started to use it today, I immediately checked it, and have the same issue: the volume being turned fully down then up - sound is faint and distant, but other channels produce a loud, clear sound. 

I don't think that this is the way the amp should work. However, the odds of having two faulty models from the same seller seems to be very low. 

How can I fix this issue? Is this the way the volume knob supposed to work?

Thanks

Hi, 

I've just recently bought the Acton II to have as a speaker in our bathroom. Looks great and sound good enough. So far I'm satisfied. 
However, the speaker is driving me mad. Here's why. 
My girlfriend and I both use the speaker whenever we're spending time in the bathroom, so both our phones have been connected to the speaker at some point. 
But, if I'm playing music from my iPhone to the speaker and my girlfriend is in another room, let's say, watching YouTube on her iPhone things get wierd. If she adjusts the volume on here phone it also messes with my music in the bathroom. 

Another example:

Playing music from phone 1 to Acton II. then, Adjusting the volume by using the buttons on the side of iPhone 1 also adjusts the main volume of phone 2. Even though Phone 2 isn't in use. It just messes with the volume of it. 

This is suuuuuper annoying. Since the app is no where near of being good, I don't know how this can be solved. If there's no good solution I'm gonna have to sell the speaker and buy a brand that really knows how to make speakers for this purpose. 

Does anyone know if this can be fixed..??

thanks / Mathias 

I have had my Code 50 for a while and have played around with it to no avail. It's 20-50X too loud. When I set the Master Volume control to something like .5 it's way too loud. I can adjust the volume within the preset but if I change to any other preset it almost knocks my house over. I think this amp is unusable and has some serious design flaws. Is there a way to knock down the volume for the entire amp and all the presets? I need them all set at around a .1 or .2.

Hello.

I'm not sure if I phrased that correctly, apologies.

I've been enjoying the Emberton for 3 months and have recently noticed that whenever I turn the volume up above 50-60% the lows fall behind and are almost not audible. It effectively sounds like I've applied a high pass filter regardless of the mobile device or media App used. This was not initially the case.

Any advice is welcome, seems like a software thing. I've been careful with it.

Woburn  speaker wont play loud volume when connected via bluetooth, but sounds normal when connected via optical1.

Hi

I have an American Performer Fender Strat, and a Marshall CODE25. I have to all the time put the volume of the guitar to about 7 in order to be able to hear something out of it with CODE25.

Just wondered, are there any tips on any possible configuration on CODE25 that makes me able to keep guitar volume on 3 or 4?

I've got an Origin 5C, about 6 months old.  Has worked fine and is a fun little amp.  But last night I had my first issue.
Got the rig set up, with front-end fx, and also some fx in the loop. Warmed it up, then played a few bars in low power. All worked fine, so I switched to full power, and stepped away for a few minutes to let it warm up some more.
When I came back, it was still powered on (light and mild hum), but the footswitch was dead and there was zero volume. Not even cable crackle when plugging and unplugging the guitar.
I messed around with all the connections. Pulled everything and plugged in directly (also checked the instrument cable). So, guitar > cable > amp. Still no volume, and just a slight hum (very slight; it wasn't ampliyfing anything, so this was just circuit hum).
I dissambled the the thing, to check tubes and connections. Everything looked grand.
Reassembled it, and it worked fine. Played for a good 10 or 15 minutes at medium volume, and it was a charm.
But then the volume started dropping. Would come in and out. Then it dropped completely, and the footswitch went dark again.
I tried connecting an external preamp into the return (with a dummy plug in the send), but no luck. Footswitch was still dark.
Hum but no volume.
Haven't tried it yet today, but I'm expecting the same behaviour. My assumption is that there is something that goes sideways when the temperature gets up.
So, two questions:
1 - Is this a power tube issue? I haven't noticed any other problems or symptoms of bad tubes. And, like I said, it's 6 months old. Never gigged, but played loud fairly often.
2 - What's up with the footswitch? I can't find any schematics of the Origin series, and I don't care to go tracing. So, I'm not sure exactly where the FS fits into the circuit. I was wondering if that symptom might help to diagnose.
Anyway, a great little amp, but it's acting up!
Has anybody had or heard of this issue?
Thanks, friends

Hello,

I took delivery of a Code50 last Friday, and already I have noticed a major flaw. I have updated the firmware, and it didn't solve the problem.

1. On many of the presets, there is what sounds to me like a slight buzz or a distorted sound as the chord is being held after about 4 or maybe 5 seconds. Obviously, this isn't going to be good when recording.

For example, I have been using many of the clean sounds, such as, American Clean (preset 32). This is a prime example of the unwanted buzz as the chord fades (only 4 or 5 seconds). There are so many more presets that also have this problem.

The issue occurs through both the Code50 built-in speaker and my Beyer Dynamic DT100 headphones. Using headphones proves that it is not the internal speaker at fault.

I can email a sound byte if you need one.

The last thing I want to do is re-box the amp and return it for a replacement only to have the same issue happen with the next unit. So, please can you let me know if this is a widely known fault because, if it is, I will unfortunately have to send it back for a full refund.

2. A second issue worth noting here is that the clean sounds are not very loud. When wearing headphones, I have to increase both volumes to 10, but I can still hear the strumming of the actual guitar with my plectrum coming through the headphones. The volume on the clean sounds are too weak and definitely not loud enough when also playing through the Code50 speaker, not just the headphones. Conversely, the distorted rock sounds are really loud when the volume is set to a low level, but the clean sounds couldn't be more opposite.

It will be a shame if I return the unit because I love the app and the ability to back up presets and also search for new ones.

Many thanks 

It's not happening always, but when it does it's frustrating.  Also, sometimes the volume (when it's only cranked up around 2) it tends to get quiter than how louder it suppose to be. Should i bring it back to the shop and ask a repair?

I have a Marshall Code 50. Not sure what’s happened but when I plug my guitar into it, I get no sound and the presets are now being controlled by the guitar volume knob. If guitar volume is full high, display on the Code quickly scrolls thru presets. If guitar volume is full low, you can individually scroll thru presets by quickly turning volume knob up then quickly back down. No volume from cabinet regardless of preset volume or master volume, only static. Have tried with both electrics I have and both cables, in various configurations with no difference.

Any help is greatly appreciated.

Thanks. Kevin.

Quite a few people on various forums are concerned about the emulated out of our DSL20H and DSLCR amps. It seems that there is a set level for the emulated line out and headphones which can only be adjusted with either the guitar volume knob of gain channel knob. The channel volume does nothing to the line out/headphones only to the speaker output.

Is this normal behaviour? Where the gain knobs are the only controls on the amp that increases the loudness of headphone/line out. 

Will Marshall provide a way to increase the headphone volume as is very low against all other devices we use such as iPhones, PC DAWS etc, so makes it very difficult to practice without disturbing the household and neighbours...

Hallo,

just received my DSL1HR now, and test it's functionality without an external cabinet (ordered but not arrived yet), so tested only with my headphones AKG K240 MKII. I noted that the volume is very low even with the volume knob at maximum level and switching the power 1W-0.1W I don't feel any difference, in both channel !

seems that only 0.1W is allowed when external speaker is disconnected. Is it broken or is it normal ? awaiting for a kind urgent fast responce please.

thanks

cheers

This is not a question but a response to those who have asked if there is a way to reduce the output wattage on Code amps to make them quieter. The short answer is no, not out of the box.

However, the speaker(s) that come with Code amps are 4 ohm. In the case of the Code 25, you can swap it out for a Celestion G10N-40 10" 8 ohm speaker (about $70 on Amazon) and reduce the output from 25 watts to 12.5 watts due to the change from 4 ohms to 8 ohms. Instead of running the master volume at < 1 when I'm jamming with my stereo, I can now run it at about 3. The added bonus is better sound - you hear the distortion from the amp itself with less mud and distortion from the speaker. This will not harm the amp in any way as driving an 8 ohm load requires less of an amp than a 4 ohm load.

Full disclosure, this was not my idea. I read about this from another Code 25 owner. Enjoy!

Which do you think is the best amp attenuator for my Les Paul Traditional+JCM 800 2203+4x12 cabinet. Plz recommend.

The problem is that when I put the distortion pre fx my amplifier does not give the sound even with any preset, the other effects work correctly only the distortion does not, however when I connect my headphones I get the distortion sound but without the headphones it sounds

Hi everyone!

Recently I bought Marshall CODE 25 and it's a great amp but I have one little problem with it.

There is a problem with MASTER potentiometer. I noticed that when I set it between 0-0.99 it is very very quiet but when I set it about 1.0 it becomes very loud. And in the effect it is very hard to play at "bedroom" volume levels. I must say that I'm disappointed - I had Yamaha THR 10 previously and it could play very well at every volume and it could play very quiet.

So to sum it up, is this some general issue with all CODE amps or something is broken in mine? Maybe master potentiometer needs repair?

My DSL401 has just started to intermittently volume drop i.e. the volume gently fades down to nothing - leave it a while, and the volume returns to normal.  Also, the effects loop doesn't seem to work as it used to - for example, if I plug a delay in to it, the delay is hardly noticeable when you play.  Not sure if the issues are related or not.  I've not had any issues at all over the last 12 years and the tubes have not been swapped out.  Grateful for any advice.  Thanks in advance.

Hi, i am using a code 50, and i cannot store the vlume levels in presets.

I am using 3 diferent presets, but i cannot level the volumes, i think that CODE dont store that.

How can i solve this ?? Its very importan, otherwise its a complete mess....all the presets with diferente volume levels....

Please HELP ME !!!

Thanks

Today I tried to connect my guitar via iRig and a common audio cable to my Code 50.

The sound was really muddy without any treble... Same when I play music from my phone over the audio input... 

Can anyone confirm this?

And is there a way to control the input volume?

Thanks and regards
