Hi all. I recently bought a DSL20 brand new and something is up with the effects loop. For some reason, when I turn it on, the volume drops way down and you can barely hear it. Any idea why? I've only owned it for a couple of months and the only thing I have running through the loop is my DD-7 digital delay.

tring to find out how i can control my 100h code amp using the gateway app but cant find out how

what to do if my bluetooth is not working when I try to search for it on my phone through the app or any other source. its jsut not there like the bluetooth was never a thing on it. this is the first time ive tried to use it and I think it picked it up once and did nothing else but show it was found. then never again. what do I do? it like it was never a part of the product

Is the programable 91009 going to work properly (AS the app does not), does it come with a cord, am I going to have to fight it as I do the app....Also, when are you guys going to fix the Gateway app. Don't give the same "we're working on it......blah, blah, blah....."And it's NOT MY PHONE.......YOUR APP is the ONLY APP I HAVE A PROBLEM WITH!!!!!!FIX THE F*^#ING APP!!!!!!!! 

Got my new CODE 100 and half/cab plugged it in and zip, nada, nothing, depressing to say the least! Anyone experience that issue? The amp turns on and everything seems to look alright, but no sound from the cab. 

It won't let me submit my registration for the warranty. I put the information it needs, I hit submit, and then it tells me "500 - internall server error". What am I doing wrong?

I just got my marshal code 100h used from guitar center and everything works eccept that its realy realy quiet. I tried factory reset and and mesing arould with the optins but nothings working; and yes i did check the volume and master knob. What should I do?  

I'm sorry to hear that MARSHALL does not provide Hungarian-language manuals for the expensive amplifiers sold in Hungary (CODE 50). This is not in the price? Not all speak a foreign language - especially the older ones.

Is it possible to play two different tube amp heads at the same time out of one 1960a cab?  Mine has the switch on the back to make the cab run in stereo mode and I was curious if it would be possible to use both inputs for independent heads.  Of course the impedance would have to be matched (8 ohm - 8 ohm), but I have no idea if it would handle the amp load properly or not.  Trying to find out for sure so I can avoid breaking something if it's not possible.

Hi,

I have an old AS80r, although the Transducer input works well, however when I plug into the Magnetic Auxiliary channel, there is a constant loud buzzing noise. Is this fixable?

Thanks, 

Please delete my post from the 28th about usb recording and an asio driver. I know why you won't make a driver now. Someone answered my question, so there is no reason to keep the post alive.

Is there any reason why the PEDL 91016 footswitch is only available at one location and that location is in the UK? Is the footswitch available anywhere in the U.S. or will it be?

hi there,

i'm pretty new to the whole cabinet with heads mixing and matching, i have only used combo's before and i am wondering about the power output of the code 100H which should be 100 watts if i am correct but the 412 cabinet is rated at 200 watts? so are you kind of limited as to what the cabinet can do or how does the whole power rating work? i ordered the 100H and 412 cab but i just want to be sure i'm not missing out on something bcs the power rating isn't correct

thanks guys!

i have a code 100 combo amp.  I like it so far, but....can i use an external speaker “and” the on board 2 x12’s too.  If so, mines horked up (sorry that a very technical musical term) if not.......sup wit dat?

I have a question about my DSL5CR Classic Gain channel. I replaced the stock power tube with a 12BH7A-STR-TAD and replaced the stock pre-amp tubes with Genalex Gold Lion ECC83/12AX7 tubes. I biassed to 100mV. I now have no discernible gain in the clean channel. I can alter the volume, but even at full gain and full volume the tone is pure clean. Did I clean it up too much or is this normal?

Why in the world would Marshall advertise right on their site for the code amps that you can record the code amp into your DAW, but not provide an asio driver? This is false advertising. Yes there is asio4all, it is not for a Marshall per se, and it doesn't work real well, it only records at 48khz, most daws will go to 96k, if not all the way to 192K? What gives Marshall? Plase put out an Asio driver for this otherwise great product. please. It can't be that hard if you can write the"code" for this amp. You are relly missing the boat here guys

Hello...I have a marshall dsl 100 and also dsl 40 C amp, need to change power tubes EL34, the ones I bought is JJ with 8 pins only, while the factory set tubes have 9 pin. Is there any issue using either of these?

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. 

I purchased a Marshall CODE 100H + 212 Cab recently.

I downloaded the Marshall Gateway app and have created a My Marshall account.

The Amp came pre-loadedwith a 100 presets.

The Marshall Gateway app also came pre-loaded with 100 presets,

but the Gateway app presets are different from the ones in the amp.

I synced the 100 presets in the Gateway app to my "My Marshall" account Library.

I have edited and saved some of the Presets on my Amp.

I want to transfer the edited Presets on my Amp to my "My Marshall" account Library, and then put them in my Gateway app, 

How do I Transfer a Preset FROM my CODE Amp to my "My Marshall" account Library?

I see the option to transfer a Preset from My Library to the Amp,

and I understand how to manage / organize the Gateway app presets from the Library,

but I don't see a way to put a Preset on the Amp in the Library.

Do I have to manually re-create it in the Library?

The My Gateway online interface is  great for managing / organizing the Gateway app presets from the Library.

It would be useful if there was as similar interface for managing / organizing the presets on the Amp, when connected via USB.

Hi are the effects pedals based on Marshall pedals
