Buzz with fuzz

[Paul S]

I am having problems with buzzing when I switch on a fuzz effect.

Pedals I use are:

guitar > Korg Pitchblack tuner > Boss LS-2 with a clean loop and a loop that has EBS Unichorus > Fuzz.

So nothing complicated.

First fuzz I used was EHX Big Muff - switched it on and it buzzed and shrieked. I though the problem was the pedal so I sold it. New owner reports everything is fine.

Now have a Bozz ODB-3. Still buzzed and shrieked.

Changed from a cheap power supply to a Johnny Shredfreak one that arrived this morning. No shriek, but still buzzes although not as badly.

It varies from bass to bass, which I think seems to indicate grounding issues with the various basses as much as the effects! Also worth mentioning perhaps that I have an old Zoom BFX-708 multi-effect that is as clean as a whistle when I have the fuzz on it.

If I turn down the gain, keep the eq on the ODB-3 reasonably flat and roll off the treble on the bass eq it is reduced. But still there.

Do I accept this as life with a fuzz or should I be able to get shot of it completely?

ta!

could be the loop of the LS-2 at fault, try the 'other' one just in case, before ditching the fuzz.

That never occured to me! I'll try that out, thanks.

please report back on this issue, as i was only thinking laterally, but have had similar probs in the past ..

Does the buzz start when you let go your strings and stop when you touch them? That would indicate a grounding issue. Check your cables too and try your setup with one pedal at a time to eliminate the cause. It could also just be that both these pedals amplify noise and feedback like a mofo and you weren't expecting the expected behaviour!

Had a rehearseal last night and was able to have a minor fiddle that was inconclusive. I have EBS Unichorus on the same loop as the ODB-3 and there is no buzz at all when that is selected on its own, so I guess the loop is fine. I used the ODB-3 on its own and it still buzzed a bit so it is looking like I need to check the grounding on the bass - at least the one I used last night. Which is annoying as I shielded all the cavities, soldered extra earth leads to it and all sorts! But I guess I still need to try each pedal with a few different basses to see what happens, if anything.

Thanks - given me food for thought and an idea of what to look out for now.
