Hi

My dsl 20hr is a great sounding amp, I have just started using the supplied footswitch, but noticed a problem. The tone changes when footswitch is plugged in, the tone is clearer, slightly louder. When unplugged the tone goes slightly darker. Also when plugged in the tone is better, more crunchy. But when I engage the fx loop, again the tone darkens, as if throwing a blanket over the speakers. I run a delay and reverb in the loop, checked all cables etc all fine. Any assistance greatly appreciated.

I recently connected my code via usb....went to ACDC preset, downloaded to test it out...I liked it but didnt save it...now when I come back to save it nothing (any preset) will not transfer to my code....It reads CODE connected....Help please!!!

Hello, perhaps I'm being thick, but the little 1 minute or so videos available through the marshall site hardly seem up to the job of properly introducing a new user to the amp and all it's functions. 

Has anyone produced a decent guide, video or written to properly explain the functions and those 'tricks' that come with experience or those featires you fall over when fiddling away the hours on the many options provided. 

It seems to me that a 'Master Class' would best help new users maximise their enjoyment whilst minimising the painful of experience of trial and error that eventually leads to frustration with sound resulting in turning the amp off! 

Help

I have a Marshall Super Bass 100W amp (American Version) I've had since brand new... I had always thought it was made in 1969 tho I'm not sure...

On the Paper tag on top of the chassis it says:

"Assembly" --> Job M      No 81

"A.C" --> Andy

"Tag Board"  --> Joyce H

"Back Panel" --> l k

"Tested" -->  T-20-69  (the T could be a 1, not sure)

Serial Number: SB/A 2231A

Thanks!!!!!

How do I register my product?

I own the Marshall CODE 100H and CODE 212 cabinet.

I really love this amp, but I find the MY GATEWAY web page interface to be somewhat awkward to use.

The following are issues that I would like to see changed.

All references to the MY LIBRARY list are referring to the list below the MY GATEWAY List on the MY GATEWAY web page.

1) On the My GATEWAY web page, the preset list at the top is arranged by columns (as it should be), but the MY LIBRARY list below that is arranged by rows.

This makes it very awkward to find a preset in the MY LIBRARY section. 

The MY LIBRARY section should be arranged by columns as well.

2) There is no indication in the MY LIBRARY section on the MY GATEWAY tab whether a preset is or isn’t in the MY GATEWAY list.

This makes it awkward to know which presets from the MY LIBRARY are used in the MY GATEWAY

I would suggest adding the MY GATEWAY preset number to the MY LIBRARY list as the indicator.

3) There is no indication in either list whether a preset has been Modified or is a Factory Preset 

(must copy to MY LIBRARY section below and then edit to know if it was changed-not as convenient as it could be if it was marked as Factory Preset or Modified in the list)

4) There is no way to compare presets in the MY GATEWAY list vs the same named preset in the MY LIBRARY list.

(And a preset can be changed in the mobile app or on the amp and synced to the web, 

but the change doesn’t get applied to the same named preset in the MY LIBRARY list,

so the MY LIBRARY presets become inconsistent with the same named preset in MY GATEWAY. 

And, there’s no indication that the same named preset in the MY GATEWAY list is now different from the MY LIBRARY version.

Must be constantly manually checking / updating the MY LIBRARY list.

There should either be a “Date Changed” field in the Edit Preset dialog box so you can know which one is the most recent, or

There should be a prompt or checkbox to update the MY LIBRARY preset as well.

There should be a way to select two presets and then select “Compare”.

The compare screen should highlight the differences.

5) Renaming a preset in the MY GATEWAY section doesn’t also rename it in the MY LIBRARY.

Requires either deletion of the preset in the MY GATEWAY list and re-addition of the renamed preset,

or edit same named preset in both lists.  There should be a prompt or checkbox to update the MY LIBRARY preset as well.

6) Multiple presets can be named the same thing but have different configurations (really bad idea!)

This makes it hard to know which one is the most up to date.

This should be prohibited.

Copying a preset to the Library should pop up a warning message that a preset with that name already exists, and ask to replace or rename it differently.

7) Preset settings can only be  viewed / edited in the MY LIBRARY section but not the MY GATEWAY section.  

This means that you have to copy a preset from the MY GATEWAY list to the MY LIBRARY section first.

Then hunt down where it went in the MY LIBRARY list in order to edit it, Edit it, and then copy it back to the MY GATEWAY list. 

That seems to be a lot more awkward than it ought to be. It should be possible to view or edit preset settings from either list.

8) It would be nice if a preset could be marked as a favorite.

9) It would be nice if all Factory Presets had audio preview samples.

10) It would be useful to have a way to record a short audio sample via bluetooth on the mobile app and then be able to save it automatically to SoundCloud and add the url to the preset.

11) Where do I find backing tracks for to use with the amp?

I am using Stanmore II with various devices via BT and i have no issue except my laptop ( ideapad 100 ) which pairs normall as a BT audio device (at first two pairing it was showing me a message that stanmore II need to be plugged in cause battery is drained and as we know its always plugged in but ok the 3 time it connected properly) but its not playing music as it displays that need to be plugged in a jack .

Hi, How do I register my Marshall amp if I live in Canada?

Hi,

I can't have a good sound when i'm using my RC Boss looper.

When I change preset, the sound of the looper, and especially the percussion, are inaudible.
Is there a way to keep the sound recorded normally?
For example if I record my loop in CLEAN, and then I switch to disto.

Thanx :)

Cant pair my code 25 and all phones in the house on the android (sumsung a70, lenovo a1000, micromax q385, sony xperia xa2 plus and others).
In the bluetooth settings, phones do not display the device name but its mac addres: "С8:DF:84:26:58:1F".
When pairing some phones it asks for a PIN code, the rest are not connected. In any case does not connect.

I get a new Code 50 this weekend and I'm very exited. Nevertheless, I have seen some posts regarding the Master Volume sensitivity  and I agree this is not nice. But there is a second issue with the Master Volume which concerns me more and I'm not sure if this "works as designed" or if this amp is simply defective:

When I turn the master poti I hear a kind of scratching noises. Additionally, the system/amp noise gets very loud the more I turn it up. I also noticed through headphones that there is only noise in one ear.

FW version is 1.11 and I know that I can upgrade but to newest version 1.4x - but I doubt this is an FW issue. 

Is this normal? Otherwise I will go for an exchange...

 PS: This seems a possible explanation to me - see https://my.marshall.com/forum/question/2544/master-volume-marshall-code-50?filterType=recent

I recently purchased a CODE 25 and love it. In the Gateway app I see a different list of presets when connected via Bluetooth versus not. Any suggestions of how to correct? 

When not connected I can see presets like Purple Plexi and Sweet Jubilee. Would like to check them out.

Thank you.

Hey everyone, 

So I've had my dsl 40c for awhile now and I absolutely love it.  However, One small issue came up awhile and i could use some help tracking down the right part. A couple weeks ago one of the fuses blew in the amp head, and after going to severa music stores,  hardware stores, home depot,  even automotive stores, i cannot find the right exact fuse for the amp. They're all 500ma, which are pretty common, but if you get one from a hardware store it just blows again immediately, because as I've noticed, the fuses that came in the amp have a thicker wire than anything I can find. Even having trouble locating the right ones online and there is absolutely NOTHING in the way of fuses on sweetwater, if anyone has any idea on how I can track down the right fuse, it would be greatly appreciated! 

Looking at purchasing an ‘89 2205 head this week but not sure if it comes with footswitch. Please can anyone advise which model of footswitch is compatible with this amp? 

I want to use two 1936 cabs with my JVM410H. Just wanted to make sure i understand the connection. Should i be using the 1x4 and 2x8 jacks on the amp, to use both 1936 cabs (both cabs are 8 ohm)? (Left two connections when staring at back panel)
