Input Jacks
You need good input jacks in your
guitar amp. When nothing is plugged in,
the input jacks short circuit the input so there's no annoying
background
noise. When these input jacks are dirty or worn out, the jack may not
short,
usually resulting in really loud static-like noise coming out of your
speaker.
I've seen some musicians spend hundreds of dollars on unnecessary amp
repairs,
"low noise premium tubes", amp "mods", shielded pickups and other $$$$
stuff when all they needed was an inexpensive set of new input jacks.
Try
it out for yourself. Next time you run into a "real noisy amp", just
take
the chassis out, turn the amp on, making sure it's plugged into a
speaker
and when the "noise" starts up, try shorting the little extra 'leg' on
the input jack to the tip and see if the "noise" doesn't stop. You can
usually clean up a dirty jack contact with some Cramolin spray and a
Q-tip
but if the noise problem reoccurs it's probably best just to replace
that
part. For those of you out there who feel challenged by
the circuit of a Ray-O-Vac flashlight, check out our groovy pictorials
of guitar amp input jacks; you'll find those on our FREE 'How To..'

amp projects, right here on our web site. Also see the schematic diagrams
of the Fender input jacks at the top of this page.
