WARNING: When using the DSL1HR head
for ‘silent’ practice or DI recording ALWAYS
disconnect the speaker cabinet from the
amplifier’s rear panel before switching on.
NEVER unplug the speaker cable from the

Can i use an emulated out with the cab speaker plugged in? 

Hello,

When I tried to charge my new Marshall Minor II for the first time, for a while the LED that was supposed to turn on when it's charging was off, but when it finally turned on, it started alternating between red and white lights every second or less. Also, every time it turned to white, it'd play the charging notification sound.

I left it there first, for about 3 hours, then the whole night, so it has already been plugged on the charger for at least 12 hours. But still, every time I take it off the charger, it shuts down and doesn't give a single sign of life until I connect it to the charger again...

Has anyone else had this problem? If so, is there a way to fix it? I don't think I'm able to replace it because it was given to me by someone else and they don't have the proof of purchase anymore.

I hope someone can help me and thanks in advance,
Adan Castro

1.  Why does my amp lose "fullness" when Gain is at 5 or below, regardless of the Master Volume knob position?

2. Does switching from one mode to another (from lo > mid > hi) change the amount of harmonic distortion if the settings (EQ, Gain, and Master on full) remain the same?

3. Does Tilt knob, when set to 10 (which supposedly mimics the Hi treble channel of a Plexi) add additional gain to the overall gain structure (Gain knob + Master volume knob)

4. What frequencies does Middle knob control? Does it boost or cut certain frequencies or just shifts the emphasis of the middle frequency region?

I have tried for ages to get this to  work with no progress. My tablet connects to my amp ok. But to get it to access the on line library so I can download. It just has become inpossible . 

I have tried everything in the browsers to hopefully turn things on . Not one bit of progress was attained.

Someone must know how this works.............Any ideas.

I noticed my Marshall Code  25 makes a hissing noise when I play through any of the clean amp models. This hissing noise is clearly audible when I play a note on the low E string. It reminds me of an old cassette tape. This is especially apparent with the cab emulation switched off. On the higher strings there is no problem. Is this normal? The hiss doesn't go away with the noise gate turned on.  I have this problem with both firmware versions 1.44 and 1.45. 

I recently purchased a Marshall Code 25. Today I decided to update the firmware.  Originally it had version 1.45 on it, but after the update it now has version 1.44. I can't find version 1.45 on the Marshall website. How can I install the latest firmware, which is 1.45?

Is it possible to combine Code 100w with MG412AG extension cabinet and have all 6 speakers work?

Hi Just got a new DSL20CR and it makes a hssing sound without any guitar plugged in. Nothing on stand by but 10 W it is present and 20W is way too loud. Playing with Reverb and presence changes it but it looks like there is a resistor problem or innefficiency.

Any advice or resolution ?

I have the Gateway apps on my android phone but I don't have WIFI at home so I can't reach the cloud to  use my downloaded saved presets.

Is there a way when I am connected to a free WIFI to save my presets to a file on my phone and then when I am home send them blue tooth to my Code100 amp. 

Thanks Tommy

Bonjour,

Pour jouer Seven Nation Army, il y a plusieurs réglages différents. Je ne maitrise pas encore le son du code 50 et je suis à la recherche des différents réglages de l'ampli.

Merci

Bruno

Good morning,

 I have a Code 25 and am using my Iphone with Gateway to control it. How do I add downloaded presets to the app so I can put them into the amp?

Hi there! What can it be, when sometimes i turn on my amp the channels simply don't response, there is no led light and no sound. But when i plug a footswitch out, led and sound start to be functional. So it rarely occurs, but still occurs. Should i worry about it? Footswitch itself works properly by the way.

Hello, 

I recently found a JCM900 4500 series hi-gain dual reverb in mint condition. The serial is Y38091---I know that it was made in 1990, I was just curious past the "Y" what the remaining five digits might pertain to? I was really just intrigued by reading the history of these and was wondering if mine is one of the first few produced and if it would be possible to find out what tubes and components were used on this one. Also, is it possible to get a copy of the original manual? 

Thanks for any and all help! I love my 900.

Does anyone have the presets for repilia from the strokes? 

Would Marshall ever consider reissuing the JMD:1 heads ? I own the 50watt and hands down , best amp head - maybe except jvm- Marshall ever made in last 20 years 

thanks 

John 

hi , can I swap out the ecc83 preamp tube in V1 for a ecc81 in a SC20H? I’m just trying to lower gain to a much cleaner sound - preferably to the origin clean . 

Any suggestions - outside of “ buy an Origin “ ;) 

thanks 

p.s REISSUE THE JMD:1 heads !

is it possible to save differents preset on the same bank  of the switchfoot instent to use just one and switch  from delay to distorcion? ..for example... i found a very good distorcion preset of nirvana but doesn't have a clear sound on it, and another nirvana preset which has a good clear sound but not good distorcion, i would like to save one of them in bank A1 and the otherone in A2...is that possible?...many thanks

Just saying: I find these almost-daily advertisement-posts in this forum very very disappointing. Let alone today - up to now - six such posts, that have nothing to do with Marshall or our concerns and questions!

I think we need a better watchkeeper here. 

Hello, i play on my marshall code 25 with a mobile phone app in bluetooth "songsterr" , it allow me to have the guitar sound on my amp with some other instrument from my mobile phone, when i use the usb cable to record on my computer , only the guitar sound is recorded on laptop, can you help me to have on the computer all the music from the amp on the computer : guitar and music from "songsterr " directly   

hey

my name is jason and i have a question. Since a week or so my marshall dsl 40 had very low volume on the ultra gain channel even when i turned all the way up. Normally my ears would explode and my mom would run upstairs. So it makes very low volume on the ultra gain channel. but when i turn my volume up all the way on the classic gain channel while im playing trough the ultra the volume is normal again. This is really weird and i have  no idea to fix this please help
