    Heya guys!
    I got a nano atm with 2 effects,demeter compulator and a stmp 01 john east preamp,
    The thing is that i generate alot,but alot of buzz and hum like a guitar with distortion on high
    Is there any way to reduce that?
    The chain is:bass-preamp-comp-amp...

  2. Hey !

    There could be a lot of sources for hum/ buzz. Here is what comes up to my mind :

    - Power isolation issues. Try to use seperate power sources or an isolated power block.

    - A defective or too long jack. Try replacing each of 'em one by one and see if things go better.

    - A defective effect. May come from a bad solder or from the inputs/outputs. Check if the buzz is still there when you get each pedal off the chain.

    - Try changing your effects order.

    - Try to rearrange all the cables, avoid that they cross each orhers and such. Also avoid that they cross mics and other amps cables.

    - Is the noise still there when both effects are bypassed ?

    - Is the noise present at home and at gigs/ sessions ?

    These are only ideas, hope this could help !

    Hum is almost always somehow related to the power supply. Which one are you using?

    Unless he's got a passive jazz bass.
