I have a 2000 JCM 2000 DSL.  I've read much about bias drift being a problem on some of the early ones due to a defective PCB main board.  Are the replacement boards available commercially free of this defect?  Is there a specific issue of board to get in order to be free of the problem?  I don't have the issue presently on my amp but am considering buying a board to have as a backup.

 

Thanks!

Dave

I own a mg100 hcfx which I am very happy with. Although it didn't come easy. It was anemic sounding out of the box but with a boost and eq in front sounds like it should.(Also a noise gate run in x pattern in front and loop quieted the noisy mg) Question: where about do other users of this amp or similar channel switchers prefer their channel volumes? I know it's function is to equalize volume between channels but is it best to equalize them towards full volumes? Half volumes? Thanks!

I would like to register my head Astoria Custom, but I do not know what to enter in the "Amp Model (Product Code)" because AST2H generates the message "Unable to find any products That match"

Team,

I'm moving back from the US to Europe and would like to take my favourite Marshall amps with me: DSL40c and JVM-1H.

The different voltage I can handle with an external transformer. The wattage is no issue, my transfomer can handle up to 2kW. The issue is the frequency,  going down from 60Hz to 50Hz. Would this be an issue with these amps?

Thanks,  Chris.

Hey all,

Feels like a silly question asking however...
I have recently purchased a new Marshall amp and inside the box it came with a leaflet for 3 years warranty.
I have made an account and registered the amp, does this now mean the warranty is active on the amp?

Dear Marshall,

I am waiting for a new shipment of Code 50's to be delivered to Sweetwater here in the USA.  They told me the shipment will be in by the end of July.

Will this new shipment include updates to Blue Tooth, or programs with current problems? 

I have no home computer, so this is improtant to me.

Thank you for your time in this matter.

Very Truly,

Stephen

Serial number V02003995E. When trying to register I can choose between Code25A, B etc.

Whichever code I choose I get an error return. I just bought it today at the American Guitarstore in Apeldoorn, The Netherlands. What should I do?

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?
