My JVM410C Combo which is only 7 months old has started making intermittent but persistent load crackling and popping making it unuseable. How should I go about getting this repaired or replaced under the warranty?

Hi, I bought a Marshall DSL40C amp in July from Gearnuts (www.gearnuts.com).  The amp has been working great until yesterday - a crackling buzz began and then I heard a pop and saw a small flash of light.  It looks like the tubes are blown out.  How do I get these replaced under the warranty?

Thank you,

Sean

would it be possible to do something like a phrase recorder in the app, maybe as part of the song player to capture/record ideas and riffs to save for playback to jam to or email to yourself as say an M4a.

Hi there, currently using the marshall vba400 with the vbc412. Just purchased the DOD meatbox reissue and I was wondering what the frequency response is on the custom 12' speakers as I dont want to overload them with more low frequency than they can handle. 

Cheers,
Matt

P.s the cab is from 1999 if that helps at all.

In the power amp eq (gain, bass, mid, treb) control knobs do not work. Only the volume knob works. On the pre amp section, all eq  control knobs are working normally.

Is it normal  ?

I just got a Marshall TSL 60 head and am having trouble with the footswitch.

Of the five buttons: Clean - Crunch - Lead - Reverb* - FX Loop*

The Reverb and FX Loop are both latching switches and work fine. The Clean, Crunch and Lead switches are all momentary and there's some sort of digital logic switching going on on the board. The problem is with these switches.

When I turn the amp on, the Clean switch LED comes on. When I hit the crunch or lead switch, nothing happens (No LED, no change from clean).

I thought it was an issue with the switches, so I replaced them. Now Crunch and Lead still do nothing, but when I hold down the Clean it switches to Overdrive for as long as I am holding the switch. When I let go, it goes back to clean.

Anyone have any thoughts why the switches aren't doing their job? Could it be a fried transistor that's supposed to be controlling the logic switching that's going on (Anyone know a good way to test this?). Some more info on the footswitch...

Any plans to release a Windows desktop app for managing presets via USB connection? I'm not an Android or iPhone user. Editing via amp panel is ok, but somewhat tedious.

Hello,

I experienced the following situation when testing my brand new CODE 50:
When I pressed the "SAVE" button for quick saving a preset, the CODE 50 completely "froze" and no sound was coming out of it... 
Then, I turn off and on the unit and everything worked again with no problems.

This happened ONCE.

After this incident (some hours after), I reinstall the firmware and did a factory reset to the CODE.
After that, the issue has not happended again.  

It really sounds as a software "bug".
Is that a known issue?
I am gently asking in order to see what to do. 
Should I return the amp to the store I got it and ask for a replacement?

If the issue is software related, a replacement might not needed, since this may be fixed with a possible update...?

Thanks.

Denis

This seems to be a common problem with the code 50 and even the code 25? When i had my code 50 it would lockup with no sound from the amp when i edited and then tried to save a preset,i would have to shut off and then reboot the amp for it to work again,this happened about 3 out of 5 times when i used the amp?Check out the user reviews on musicians friend for the code 50,three reviews mention the same problem that i had with my code 50.

 

Marshall should look into this problem and try to fix it with a firmware update or find some other way to fix this problem?If marshall can fix it i would most likely buy this amp again.
