I would think the other way, IF you hear fuzz or hear anything at all, your input is fine, wiggle the speaker plug around and listen for changes. You probably have a dirty socket on SPEAKER OUTPUT.

    I would also wiggle the master volume and check as well. If it is static and scratchy, just working it up and down to see.

There is clearly a problem with your input jack or cable. This should be covered under the warranty.

Check your input (guitar signal).
Also, check your gain and volume levels.
Make sure that you have a reliable, steady, and clean power source as well.
If the problem persists, contact the store from which it was purchased. There are a lot of things that can go wrong internally with the cheaper Marshall models.

My ltd deluxe ec-1000(vintage black) is not producing any distortion on my Marshall mg100hdfx. this is the first time i have had an active pickup guitar, i put a new 9v battery in it but still no change in...


Distortion is not produced in the guitar. Distortion is generated in the amp by circuitry that increses the gain until the waveforms "flat top". This creates higher harmonics and a buzzy sound. If you are getting a very low output from your guitar it is possible that you don't have enough output to get the distortion in the amp to work. Other settings in the guitar add harmonics by mixing more than one pickup. This is not ditortion but adding these harmonics changes the sound immensly.
LOOK AT THIS SITE AND FIND A SCHEMATIC THAT MATCHES THE RESOURCES OF YOUR GUITAR... You might be able to figure where the wire goes... It may be a ground.

Marshall MG100HDFX, VERY loud painful humming/noises as soon as the amp is turned on. Cant be adjusted by volume or anything, is this a connection problem?


Likely the filter capacitor(s) have failed OR the power amp has shorted driving DC with ripple into your speaker (very bad). Take it for repair before damage might be done.

I have a Marshall MG100HDFX 100-Watt Amplifier half stack (solid state) and I now am not getting ANY sound out of the amp. I changed the fuse and the power module behind the fan, and still no sound,...


plug headphone in the effects send jack...If you get somme sound (won't be too loud) there, that means preamp sections are probably ok. Drive a signal into the effects return jack... If power amp responds, it is OK... If both these are OK, then suspect the switch contacts on these two jacks that forward the preamp to the power amp when effects unit is NOT plugged in.
These contacts are a chronic problem.

The sound on my mg100hdfx cuts out sometimes then its fine what could this be


Common problems are broken or intermittent input jacks or cracked circuit board or soldering or broken volume controls. Another one is a bad switch contact on the jack for PA input connection. All these are internal and require servicing.

External problems are guitar and cable problems.

I can turn it on and i hear the fan going...but it doesnt make any sound when i strum or anything...please help!


There are some basic things you can try before you suspect the amp. Does your guitar cord work in another amp? Is your guitar sending sound through your guitar cord? Without any thing plugged into your amp can you hear a slight hiss when you turn your controls up on your amp? Here is a link to some things you can do to troubleshoot the problem:http://www.geofex.com/ampdbug/ampdebug.htm Even though the info is for tube amps a lot of it also applies to solid state (transistor) amps like yours.If it turns out to be the amp and you don't feel comfortable working on it and have no one that you know personally to do it you are best served by taking it to a certified Marshall repairman who will have the tools, parts and schematics to help you.

MG100HDFX Amp - crunch setting seems too loud


There are 2 channels, Which means there are 2 sets of knobs ... One for clean and one for crunch. Start out with a low master volume and set up the crunch, Then the clen and switch between the 2 and make adjustments until they match volume wise ... Then turn the master up.

Feedback noise when overdrive is on


it could be your guitar pickups. try using another guitar or getting your pickups waxed at your local music store. also if your playing in a small room kind of loud, or if your using single coil pickups (like fender statocaster pickups) you will definitely get a feedback noise. if that does not work let me know.
