Marshall MB4410 - Dies and comes back to life every few minutes..

After about 30 minutes of playing, the amp started to lose volume and stopped all together. Two minutes later it will start again but do the same thing over and over...Every few minutes it'll come to life and then die while the light stays on. Any ideas?

Our bassplayer had the same problem with his mb4410. As it turned out, the fan was not working when the amp got hot. It did turn when cold - go figure! Swap the fan for a good quality (Pabst, Sunon) 80mm pc fan with 2-wire connection. Three or four wire fans will not work w/out modding. See your local pc guy and ask for an unregulated, silent 24/7 fans. He will know. Our bassplayer sold the P.O.S. while still in warranty. HTH.

Its a possibility that the amp is overheating, and for that reason the thermostat opens, when it cool down it close bringing the amp back to life

Hi I have A Marshall JCM 2000 TSL122. It starts out having full sound then all of a sudden no sound then after a few seconds, minutes or several minutes sound is back!


I suspect it's your input jack if it stops working immediately and comes back immediatly rather than fading in and out. Give it and any other jacks a good cleaning and see if it helps.

Marshall MB4410, with low volume gives no real volume,


Guitar amps have preamp sections (think unpowered audio mixer) and power amp sections (Crown rack-mount amp). An excellent way to isolate audio problems if amp is still producing audio is to check the preamp out (line out). Preamp output distorted = preamp failure. Connect MP3 player to "Power Amp In"...sound distorted = power amp failure. In your case the latter is the case as your "line out" is clean. Also test each speaker for clear sound as speaker cone damage from being overpowered is fairly common. At 300w. I'll assume the failure was not from cranking the volume to loud but a shorted speaker or speaker wiring could zap the power amp in an instant.

Low volume on my marshall


I am very new here and don't know how to answer a question to a specific problem so I will write about the most common problems that I have had over the decades doing guitar amp repairs. If you find that your amp is extremely low in volume and then suddenly comes back to normal- check out the effects return [or power amp in] jack. Especially in Marshall amps-these corrode and your signal dies. If there is loud noise such as hissing and crackling with no guitar patch cord in the input jack- the input jack is likely at fault. They normally have switching contacts that ground part of the input circuit when the 1/4 inch male plug is disconnected. When this in is corroded or too weak to make normal contact, you can get these symptoms. If your amp is a solid state Marshall or Fender and there is a random buzzing sound with no guitar signal connected- hit the side of the amp and listen for the buzz to go away or become louder-if it does, this usually means that the connections are loose at the two large filter capacitors. In one or more Marshall amps, they use a filter circuit in the low voltage power supple for the preamp tubes. If you encounter a dead Marshall[the model escapes me now] remove the circuit board and resolder the four connections at the bottom of the bridge rectifier. If you have any other amplifier repair questions you can email me direct at computerlen@hotmail.com.

I bought the amp a few weeks ago and it worked perfectly for a couple of days and then for some reason the controlls just froze. the tap tempo light went out and the channel control light stayed the same...


Exercise your warranty IMMEDIATELY since you just bought it! If you bought this used, you LIKELY bought someone else's problem. The problem is likely in the digital effects area... probably a bad cable contact... but if under warranty DO NOT mess with it... return it for replacement or repair.

My Marshall Haze 40 Amp started making a very loud humming noise after a couple hours of playing.I let it cool down,and turned it back on and the noise came back after a few minutes


may be one of the electrolytic capacitors in the power supply has become leaky...this is a common problem among amplifiers...so you let it cool down..then after a period of time the capacitor heats up and then causes the hum...the power supply caps filter out the 60 hertz ac line noise...which is probably the frequency of the sound it is making...this is a good indication of these caps going bad....another thing you can check is to see if the amp is properly grounded(eg: the ground pin on the plug is present) and that you dont have an open cord or input

My marshall G80RCD plays perfect...but every now and again...for no reason...the volume will spike to explosing levels for a few seconds. Thoughts?


A wild guess is that the soldering on the cold side of the volume control pot MAY be bad. When it vibrates and loses contact where it is soldered, the unit will go to full volume. Check soldering of ALL the pot leads into the circuit board. Look for a thin grey line around the lead part way up the menicus of the soldering.

Hello, well i just bought this week an MB4410 marshall and it sounds a lil bit distored even at low volumes and on the clean modern channel, i just wanted to know if thats how the amp should sound like or...


First make sure your guitar can't "hear" the amp as the sound can rattle the strings and have a form of feedback. Stand with your back toward the amp for example. If that doesn't help, take your guitar to the dealer and try it on another of the same type... see if it does the same. Also where you use it, make sure nothing is rattling in the area that can fool you as to how it sounds...

My marshall classic reverb 30 makes sound some times and some times when you play with the volume knob it stops


The volume control knob PROBABLY is broken, dirty or has bad soldering to the circuitry.

Use some CRC226 in the control if dirty. While you have the unit apart, check the soldering and for any circuit board cracks.

Marshall DSL 100 - volume fades away and gradually comes back on


IF this is a vacuum tube unit, these symptoms are that of a tube that the heater is intermittent, that is it cools off due to a break and then liights again.

Open the back and observe the heaters in the tubes. DO NOT be fooled by some that have TWO heaters in them. (use a mirror if necessary) A single one that comes and goes can cause the problem and the voiration can make it come and go. This behavior in a tube is NOT somthing readily spotted in a tube checker. The delay in fading and coming back would be the delay in warm up following a heater going out and cooling.
