Can a bad cable cause microphonics?

[Milothicus]

i can't see how it can, but it seemed like it last week...

chain: mim jazz with 62 RI pickups -> behringer tuner -> yorkville amp. my cables are the cheapest planet waves cables...

i was practicing, and noticed that tapping on my pickup cover was louder than usual. i thought the pickups were falling apart and would need to be replaced soon, or (re)potted.

i kept playing, and then my volume knobs started acting more like tone knobs. i started jiggling plugs and moving things, with no effects.

i unplugged and plugged using one cable directly into the amp and everything seemed fine after that. he microphonics were mostly gone. i even used the same cables and setup the next night at a small show and everything seemed fine...

is there a particular fault in a cable or my wiring that might be causing this?

problem hasn't returned, but any electronics experts know what could cause my volume knobs to act like tone knobs?

Cables can add capacitance dulling your tone (especially long curly ones) but that is a 'one trick pony'. In short, no, your cable doesn't case those problems.

I would check the wiring on your bass, make sure nothing is earthing in the wrong area, loose or just wrongly connected.

Other than that just improve your rig. I wouldn't touch Behringer gear with a barge pole these days. The Korg DT-10 tuner is sent from heaven!

i guess if the signal at the pedal end of my cable was disconnected, the cable could act like a tiny capacitor to ground, couldn't it....

i'll take the bass apart and check the wiring too...

i've since bought some nice Canare cable and G&H connectors from bayoucables.com. i've never had such an easy time soldering. those connectors are amazing...
