Lots of noise and hummmmmm.

Ok
I´ve read all your hum experiences and did some tests:

- Connected the jack directly between the guitar and the amp (without breadboard or any effect) and there was some low noise.
- Connected the input jack to the breadboard and then the output jack to the breadboard too (just serial direct connection without any effect) and the noise got louder. It seems the breadboard is making some noise.
- Connected the input jack of the guitar to my digitech RP80 pedal and choose to bypass the guitar signal to the output jack (amp). I got less noise than on the breadboard but some more noise than connecting the guitar directly to the amp.
- Connected the input jack to the pedal RP80 and choose a high gain distortion/fuzz and connected the output jack to the amp. GREAT SOUND AND NO NOISE AT ALL EVEN LESS NOISE THAN CONNECTING THE GUITAR DIRECTLY TO AMP.

So my questions are:

- It seems that my RP80 pedal has some noise filter on the effects but not on the bypass ( i dont know if its true bypass). So how do i make a filter like that on a high gain effect like a fuzz?
- Why am i getting some hum even connecting the guitar directly to the amp? I´ve tried two diferent jack cables with not much noise reduction difference between them. Is it the cables? Is a bad grounded amp? Is it a bad grounded guitar?
- I´ve tried on the breadboard to connect the input jack in series with a 100ohms resistorand output jack and in parallel a 1nF condensator connected to the ground but with that i get no noise and no sound of the guitar ( i saw this at musique.com website of how to reduce hum). Am i doing it wrong?

Please can anyone help me out im getting crazy because of this problem. Yesterday when i went to sleep i could still hear the humm in my hears
