Make sure you have a ground prong on your power cord. Most input jacks nowadays are closed circuit. They have a switch built in that won't allow any sound without the cord plugged in. You may have a damaged jack that will give you a loud hiss, a loud hum or crackling depending on what volume your controls are set at.

Here is the page you need:http://www.fender.com/support/amplifier_schematics.php Look under hard copy archives if you can't find it in the newer section. I emailed them at [email protected] for a manual and schematics for a Fender Sidekick 10 and they emailed me one right away and were really nice. Please let me know if this helps.

The frequency of the A string when in tune is 110Hz.
What you are hearing is actually 120Hz which is the second harmonic of the 60Hz power frequency. It would be hard for you to distinguish between 110 an 120.
Try this test: Bring something that produces a reasonable magnetic field such as a wall wart power adapter that is powered near your pickup... Then you will be able to see that you are picking up stray magnetic fields from your environment.
Humbucker pickups attempt to quash such pickup by winding the pickup so stray magnetic fields cancel in adjacent coils.
Some pickup CAN occur on your cord and also in an amp.
If you leave your cable unplugged from teh guitar you are LIKELY to pick up some of this hum... The second harmonic pickup is COMMON when devces like full wave rectifiers are driven by transformers in the area.
