I just got a new CODE50 and am extremely pleased with. My problem is everything on the Gateway app works, but the GAIN, MIDDLE, VOLUME, and PRESET knobs on the amp don't work. I'm really pretty new to this so I'm not sure if something is wrong or I'm doing it wrong but every other knob works correctly.

I'm trying to get the specifics on my head's history.  It's a 1987 2203, with the serial code labeled S/A.  However, the sticker has hand-written specs saying:

Model: 2203

Power: 100 W

Power Input: 375 W

As far as I know, "S/A" models are 50 W.  But how come mine says it could be 100 W?

Hello!

Have a 6100LM three channel head. The footswitch that comes with the amp is huge - it takes up a large amount of space of my pedal board and I only really use it 3-4 times during a set (swapping from crunch to clean and back, never really use the lead channel). Does anyone know of a smaller replacement footswitch that could do the job? I only really need "channel up/down". I know the head has midi switching but this kind of thing is not my strong point......

Appreciate any help I can get!
Best

Hey

Problems with the lead and crunch channels on my 6100LM head - on both channels the tone and volume disappeared leaving a trebly tinny sound. It also seems like the tone controls on each channel do not work. Any idea what the problem is here? Appreciate any help you can provide.

Best, Andy

Hello, I just got an old AVT150H, I will use this AMP with a MG412CF Cab. AMP: 150 Watts, and the Cab: 120 Watts, 8 OHM.

Can I use it normally?

What if I get a second cab (for full stack)? Can I get another with 120 Watts? Should I better change to bigger cabs?

so what series is the vavlestate 10 and valvestate 40V?    can't find them in the manuals section

Hello ,,, being new to this site and Marshall amps hope I don't sound to dumb...  Can I go out of the line out on my valvestate 10 and into the input on my valvestate 40V?   

I lost the retaining nut(and washer?) for the Input jack on the front panel of my MG10 Amp. Can I buy a replacement from you?

Another question about the Code 25.   I'm configuring using the amp selector switches.   You've said everything that can be done via the Gateway App, can be done via the amp controls.   In the Gateway App, it allows me to individually turn on and off each pre-fx, such as Distortion, Compression, and Pitch.   I cannot figure out how to individually turn on and off these pre-fx devices via the amp controls.    It appears to either turn them all on or all off.  Even when I turn them off, every sound appears to be compressed (even when I set the power resonence to a high value) and its really annoying me.    When I had the Gateway app working properly (see my previous question), I was extremely happy with the ability to control these pre-fx settings and the Code 25 amp sounded awesome!   Now, since the Gateway has stopped working and all sounds appear to be compressed,  I'm ready to return it......your help is appreciated.

my Marshall 2555, I have to change the voltage and the ohm rotory switches, now the one's in the aamp are an 8pin with a jumper going from the #3pin to the #6pin, but the new replacement switches are a 6 pin with what i assume is a ground pin in the middle, so my question is do i run the jumper from the #3 to the middle pin. pictures would be nice since i can't seem to find any information at all on the net,or u-tube. I would hate to do a trial and error wiring thing.

I recently purchased the Code 25 from Guitar Center.   I downloaded the app to my Galaxy S5 and paired it with the amp.   Day 1 everything worked fine.   Day 2, the bluetooth connection is dropping whenever I make a setting modification via the app.....very frustrating as this did not happen Day 1.   Can you help?

One more piece of info, the bluetooth connection actually stays active after the Gateway app drops as I can still play audio from my phone thru the Code 25.   It is the Marshall Gateway app which drops the connection after I make any change.   The app appears to drop the connection as soon as I strike any note on my guitar.       Once the connection drops in the app, it will not reconnect.    The only way I've gotten it to reconnect is to drop the pairing and re-pair.   Interesting that when it 'pairs' it always produces a new pairing code.

I cannot find my model number in the dropdown list

Serial is T40052, It's 1x12 master volume JCM 800 super lead with channel switching.

4210 - 2205 basically

When i try to play a track to my Code 25 using gatway on my motorola droid turbo 2 running android 6.0 the search window opens but remains blank other then the ok and cancel buttons at the bottom. Please help. thanks!

what model number footswitch goes with the avt150h  (head unit)?

Using my C5 combo as a head to the C110 cabinet, is there a way to have outputs on both the combo and cabinet?

Where may I purchase an AVT 2000 6 button stage controller or parts to repair one

What options are available to replace the stock 4 ohm speaker that comes in the Code 50?  I would like to upgrade to a Celetion or something similar.  The stock speaker flutters at volume when using the heavy distorted/gain presets.  Any recommedations?

Just purchased a new Code 25 amp and about every 30 seconds or so it looses its bluetooth connection and I have to go back to the connection page to reconnect it. Often after reconnecting it looses connection again before I can even back out of the connection page and make any changes to the amp. This is very frustrating. Ive checked for new firmware updates and there are none. I have seen others on forums complaining about the same issue. Is there a fix?

I am running Windows 10 on a compatible laptop and get an error message when I try to run the Marshall update utility software. It occurs after a "verifying application requirements" window pops up. The error starts with "An unexpected error just occurred. Cannot create instance of main window"?

Any advice?

When I save a preset in the app the preset will multiply as in there will be more than 1 of that location and none can be used.  Is there any way to fix this? I tried deleting and redownloading the app but it happened again. Thanks!
