I bought a brand new MarkBass LittleMark III for maybe two months ago, and after a band rehearsal at Sunday, I noticed now that the sound has a lot of buzz to it.... I don`t know the exact words to explain in english, but it`s the first time I hear it and it`s definitely not supposed to sound like that!

On Sunday, I played with a borrowed fender p-bass, where the pup has much more output than my own bass, at least it seems so since the clip-LED blinked several times, even though I turned the volum under 12 o`clock....
can this clippings have caused a fuse to go or something?
I really have no idea...but I`m kinda panicing unsure.gif

any ideas?

UPDATE!
The amp was a 110 % functional!


The unwanted noise is surprisingly coming from the cabinet (which played cleanly the day before). I`m pretty sure a part, or more, is loose.

Clipping and buzzing and hardly the same,
clipping would add bit of overdrive to your sounds,
that's what clipping is actually.
Buzz on the other hand can be caused by many things,
one screw loosen a bit to the whole amp is "buzzing",
or one note that causes resonance to some piece of amp etc.
I can't tell more since I don't get if it was buzz or clip. smile.gif

On my bandreahersal, it was clipping

Now I`m playing at home at low volumes, and I have this noise.

Almost like this: https://www.youtube.com/watch?v=h6AkfXgNx0c

not so intense ofc, but when I play hard, the sounds are very similar

Perhaps something is wrong with the amp. Have you checked several bass guitars on it? Have you swapped the cable, changed the wall outlet, possibly some effects could be causing this as well. Check all these things and see if you can localize the problem.

Oh my, that's Chicago, I almost went up on that tower
but waiting time was more than one hour so we passed. biggrin.gif

Anyways, it seems like AC buzz, at least at your home,
check out cables, outlets, turn off TV or any other device just to be sure.

As for clipping at rehearsal, it could be either input in your amp working wrong
or you simply played louder than usual.
Tiny clipping shouldn't scare you tho, it's "healthy" to have bit if hotter tone.
I guess you have separate input (volume) and master pots on your amp
to dial proper input and then overal volume of the amp?

I have the guitaramp as well on the same wall outlet, and tried all cables at that amp, including the bass. Clean tone without no buzz...so I fear it`s the bassamp sad.gif
Will bring it to my luthier today, and see if he`s able to do som magic!

Take it to amp tech mate, or if your luthier can fix it, then you can take it to him ofc.

I will do, I`m hoping that the amp is new enough that the guarantee will cover it all smile.gif

Hmm its best to take it to a tech. There is a switch behind the amp for "ground/lift" maybe has something to do with the issue. But be careful with that since I don't know what is broken its best to have your bass amp grounded.

If you have warranty, definitely take it to qualified technician/service with a warranty papers. This will ensure that you get the services for free.

If it's new you still got warranty in affect. Take it to the shop.

The unwanted noise is surprisingly coming from the cabinet (which played cleanly the day before). I`m pretty sure a part, or more, is loose. So tomorrow I`ll bother him with my cab instead tongue.gif

Great man, it's good that you localized the problem. I hope it is just a minor thing, like a bad wiring or something, it should be very easy to fix.

That is a relief! I hope he will be able to diagnose and fix the problem with the cab! smile.gif

Another update!

We opened the cab and found the following: some loose carton rolls, and a capo stuck to one of the magnets laugh.gif

I was hoping that it was the capo (no wonder what it did there, must have been the previous owner) that was making the noise, but still buzzing after we took it out.

We ran some more testing and found out: (dunno if this translates directly to English, but I`ll try) I had blown/overloaded the horn at my cab, so when we disconnected it, the buzzing disappeared as well. It will cost me about 150 $ for a new one, so I`m not sure when I bother to fix the problem since it`s of a minor sort tongue.gif

hahah that is crazy smile.gif How did it end up there? smile.gif Sorry to hear about horn, some of them have a glow fuse to prevent overloading but it happens. If you don't miss those highs you don't need to replace it though.
