Guitar amp make large crescendo-like noise, loud pop at end.

I posted this up recently and am adding a bit more info- I have an approximately 1-yr old Fender Deluxe Reverb-Amp and it has recently begun to make a noise-floor like sound that increases in volume until it pops really loud at the end. I tried unplugging both the footswitch pedal and also the speaker jack and it still makes the noise, randomly, and repeatedly, whether the volume is up or not. Moving the pots makes no difference; it seems to be coming from an internal isolated problem. thank you for the help!

Same loudness, no speaker? This sounds (no pun intended) like a filter capacitor shorting out. Open it up and VERY CAUTIOUSLY look for what is making the noise. Filter capacitors can eject hot stuff. Very dangerous.

Guitar amp continuous humming from speaker


Firstly, do not disconnect the speakers from the amp when it is on. Damage is possible.

You have a bad ground somewhere in the hookup. The first suspect would be your guitar-to-amp cord shielding connections at each plug, then, the wiring in your guitar. Try changing each of these to another as a trial, one at a time.

Zener diode and hum in guitar amp


It could be the diodes, but whatever is the cause it's before the pre-amp section. Generally a loud hum such as that with no effect by volume control, is mostly caused by the filter capacitor in the power supply. And that hum is the 50HZ mains hum getting into your system!

My H/K 430 amp making a low frequency, very loud white noise that drowns everything out after it's been on for about 10 minutes


My strong, strong guess is that the large filter capacitors on the power supply have come to the end of their life. open chassis and remove (desolder) the power capacitors - large cans - and replace with new capacitors of similar ratings (voltage and uF). This "noise" will be more like a fuzzy tone of 100 (Europe) to 120 (USA) Hertz which are pretty low frequencies.

When plug in guitar to amp, there is either no


Try a different guitar and cord. If still problem, give the amp a bump without guitar plugged in. If amp makes noise, there is an intermittent internal connection,

My amp won't play distortion.


Hello all you have to do is turn your master volume down to just barley on then turn your pre amp volume somwhere about 2:oclock depending on how much distortion you want ajust your volume on your guitar a little past halfway to give yourself some headroom in case you need to turn up some while you are playing! just think of it as your guitar is your first pre-amp then your amp is second preamp in line ,that is your over drive ,then the master volume is how loud you want the overall volume i hope this help's ya!

Elevating loud noise and pop


Hi melissa961

Not sure what make and model your rig is but the symptoms you have are classic for a failing transistor or capacitor. There is not a lot you can do about this except trace down the faulty part and replace it. We do this in the workshop by cyclic heating with a heat gun, and cooling of individual components with freeze spray until we locate the offending part. If it is a year old, I am hoping that it had a 1 year warranty, and that you are close enough to the end of it that you can claim the repairs as warranty. Sorry that this does not actually fix the problem for you, but now you know what you have to do next. Get the amp back to the retailer you purchased it from. Hope it all works out for you. If my advice has helped to resolve the problem for you, a FixYa rating from you would be great. Cheers

Crate RFX65 solid state guitar amp has power but no sound


Hikonartist87

Sounds like the amp has developed a problem. If you had it LOUD then you may have popped a speaker or an output stage. You say it still makes the plugging in noise, what happens when you touch the end of the jack lead whilst plugged into the amp. do you get a burst of clean hum?
