OK right. So recently I have been having problems with buzzing in my amp. It's not the kind of buzzing you get when you turn the volume up to 10, if you know what I mean. If a jiggle the cord where it plugs into the guitar, then that might stop it, or sometimes when i jiggle it where it plugs into the amp. This would seem to me to be a problem with the cord ( i sure hope not with the guitar or amp). Is there any way i can investigate fix it, or am I better off just going and buying a new cord? It is very annoying, even though it doesn't always happen, when it does it usually doesn't stop.

get another cable.. then mark one end of the old one with a sharpie.. plug it in the guitar and then in the amp..  giggle both ends to figure out which end is shorting out..  after you do, let your electro-geek bud take 3/4's of a inch off the cable and soldier the end back on.. you'll have two cables then.. in the event that the new cable still crackles.. that's when you start to worry about amp or guitar... but again, simple process of elimination from the least possible to worse possible case can maybe save you a little money.. rather then getting panicy rushing out to buy a new amp or put the axe in the shop to have expensive repairs done.. the simplest tasks you can do for yourself if you just take time to read material on it then be solid when you do it..  and always when you take something apart.. even the cable ends.. remember exactly how it came apart.. draw diagrams if you must, that way you'll know exactly how to put it back together.. can remember seeing young up and coming techs forget to put the cable back through the outer sleeve before soldiering it back together.. have a good strong soldier, but on an open cable.. 

hey I have a genz benz bass amp with a short in it...
when I get all this stuff put together right in my studio,
I'll have a little room to be able to tech on more..
so when I am able to break it open, I will start by
checking the input jack, then the volume pot. then will
start looking at digging further into the circuit...
it's like my piano. I had spend the last year or so
scared it was going to be a discontinued circuit board
or something and I would have to loose my controller
till I could save up at least a good $500...  but bored
and waiting on the real electronics engineer to get his
tired half dead carcus out of bed, I tore it down myself..
luckly I figured it out pretty quick.. that part of my baby
was split into two halves, each a bank of momentary switches..
from there went via ribbon cables into the pc boards..
p.c. here means printed circuit...  already had figured it
wasn't one of the boards since it was a problem common to
all three a flats below middle c.. so from there it was as
simple as finding the short...  so rather then stressing it, I
took and warmed up the ol weller.. and proceeded to touch
each physical soldier joint for just a quick few seconds, long
enough to reseat the soldier... steve had gotten up about
that time, and so when he had shaken the cobwebs out a
little, looked over the circuitry and what I had done.. I had him
add just one extra drop of soldier to the one spot I was uncertain
about since I had lingered a little to much on it with the iron..
he then put it back together and congratulated me for a job well
done.. you see, as musicians of music that is generated mainly on
computers, kids today don't have to know how to tech on that
much equip.. but to learn a little general spot tech knowledge
will never hurt and can save a few $60 bench fees for someone
finding what you could have.. after you do learn a little bit.. well
it's not bad to then let someone else fix it if it can be fixed..
so you'll save enough in bench fees to replace it when something
really is seriously wrong with it.. the amps are mainly what I speak
of here.. but getting this kind of quick tech knowledge will also
allow one to save when it comes to fixing simple shorts in their
guitars, all the way to being able to changing out your own pickups..
completely rewiring a guitar won't be that hard of a task either...
just will take a little reading and understanding of what has to be
done.. short of midi equipped guitars, there isn't enough places
one can be messed up.. you'll find mostly at the input jack, the
switches and then the pots will usally have a lite duty job short
to be re soldiered... and then you worry about the pots and lastly
the pickups..

Dan

deff sounds like a cord issue..you can get cheap ones from www.musiciansfriend.com
