I have a mg15cdr that I 've for a few yrs bought new but not used that much,everything works as it should but when I switch it off there's a loud pop/crack sound,it's done this since I bought it,I've tried turning the knobs all to zero before I flip the switch this has no effect,if I switch it off at the socket it's lots better.

Any ideas would be great

Today my neighbor came over to jam and brought an electronic pedal  arena 2000. I noticed the guitar volume was much higher than it should be as I had the volume on input 1 all the way down. We unplugged the pedal and found the amp volume would go up and then down as we played, we plugged a guitar into input 2 and found that both guitars would ramp up and then down.

the amp is 15 years old and doesn't get much play as it's a bit too much for the small room (realistically it may have 100 hours total at lower volumes), it has been parked in same spot all this time.

any help would be appreciated

I am having problems with the new firmware on my code 25 and gateway app on an iPhone.  It used to work fine but now gateway is not connecting to the amp.

Hi, I have an issue where playing some notes in fifth octave like g5 weirdly resonates with some internals of the Amp amifying the note to unpleasant degree at the start of the note and even more couple of seconds later. Notes close to it behave normally. 

This happens on both my guitars, both through the speaker and headphones on any cranked high gain Amp. My other two amps do not exhibit the same issue as well as boss gt-1000 connected to my code with ever section of it turned off.

Please help me troubleshoot this. 

Obviously, I have updated to the latest firmware and did a factory reset after. However, neither of this helped. 

My ACTON II has a problem with connection and all LED's are acting weird. Unfortunately when I'm trying to create a ticket for repair there is no SERIAL NUMBER sticker at the back. Can you help me on how to process this?

I have bought WOBURNIII - like to have an AMP which model from Marshall suits my speaker system; As i have bose speakers too. Please advice.

Ideal to have an AMP to enhance my Sound Experience, as we have limited functions on the Marshall / Bose Speakers.

I just bought the Marshall Code 25 Amplifier. Whenever I plug my guitar (Epiphone Les Paul Custom Replica), sometimes even just the cable into it, it makes a buzzing/ticking/crackle noise - sometimes both at the same time. When I play sound over Bluetooth or nothing is plugged into the "Input", it does not make the noise.

The guitar, plugged into a different amp (Cambridge Audio with Bose Sound System) with a different type of cable (RCA with a 6.3mm adapter at one end), also does not make the noise.

So either the amplifying circuit/chip in the code 25 is fried, or the cable (normal 6.3 on both ends) is.

Worth to note: the Guitar, Amp and the normal 6.3 cable are all brand new.

Do you know what can cause this and how to fix it, if the Amplifier is fried I can just return it within 2 years.

I have a Marshall DSL40CR. It came with EL34's as the title says. I decided I wanted to try 6ca7's and was told they are essentially drop in replacements for EL34's. I had the EL34's biased at 35-36mv. When I put the 6ca7s in, I was shocked because the bias was 70mv. I lowered them down to 35-36mv.

My question is: Should the 6ca7's be biased to the same number I had the EL34's at? Should I go higher or lower? The reason I'm asking is that most Marshall techs say 35mv is where you should be at with EL34's to sound their best. Is this the same for 6ca7's?

There is also a very slight burning smell in the rear of the amp. Don't know if this is just something about the new tubes or if it's cooking the amp....sounds fine though.

Могу ли я использовать наушники Bluetooth с усилителем Code 50, чтобы играть на гитаре и слушать ее? У меня есть Bluetooth-наушники, но они не работают...

Hi I have a JVm410H and I'm looking at buying a Gig Rig G3 programmable footswitch so I can store various pedal combos, and then switch with one push, both the pedal combo I want and also the Marshall channel I want at the same time.

Is this possible using a) the Marshall footswitch or b) using the MIDI In/Out on the head?

Any help most appreciated

Cheers

Can I connect the amp to my computer and record my guitar? how can i do that?

Hey there. I love my Code25. Everything was just perfect for about 3 years, including bletooth connection and USB. Updated last time to 1.48. It is still the latest. But recently, with same cable and same W11 laptop there is no connection.  I read some posts and few suggest USB interface may burn out. It is true? Any ideeas on this?

Guida all'uso dell'app Marshall Gateway

ciao a tutti,

ho appena acquistato un Marshall MG15 Gold, ma appena lo accendo (anche senza cavi collegati) si sente un fruscio di sottofondo. E' un difetto di fabbrica?

My Emberton II turns on with no sound and it's bluetooth is not discoverable, I tried resetting by pressing for 7 seconds. Still it's not discoverable and can't connect to any devices. 

How can I fix this?

Please help me

Hello all

I am using a Code 25 together with a PEDL-91009 footswitch.

but it is not running, I am not getting different volume when changing the preset.

Your help is much appreciated ;-)

Kind regards,

Please could Marshall and Softube create a new Amplifier with new effects and new improved amps and speaker Cab's..... Maybe call it...    CODE-X....

or something like that...

I own three Marshall code's they are incredible.... Please I think Marshall and Softube are the best thing since Peanut and Jelly....  please continue this great pairing...

Thanks Allen Perez

I bought the Marshall stanmore ii from Amazon, and I can connect and play music normally after I bought it.

After I updated the firmware from the APP, I found that the machine was unresponsive when I tried to restart it.

Now when I plug it in, nothing happens. 

I would like to ask if there is a way to solve the current problem. Thank you

Hello. I need to find out if the Marshall Acton 3 speaker has the ability to pair with other speakers from this series, just like they do in Series 2.
