POD HD in south korea getting a lot of humming sound when using a guitar

Hi

 

Im getting alot of hum and fuzz sound from my POD HD when my guitar is plugged in. It's most noticable on presets such as master of puppets and distortion effects etc.

 

I live on the 10th floor in a fairly new 20 storey apartment in south korea and am wondering if this is a grounding problem. The south korean  plug only has 2 pins with no third pin for grounding so Im wondering if buying an adaptor that has a ground pin would help reduce the hum.

 

The standard voltage in south korea is 220V with a frequency of 60hz. The standard plug used is a type C though type F (grounded plug) can be used.

One thing i have noticed is that sometimes the hum is reduced when I place my hand on the guitar lead right where its plugged into the POD HD guitar input or on the power input to the unit.

 

I hope someone can shed some light on this.

 

Thanks

 

Stu

      It sounds like a lack of a ground connection is causing your issue.  I don't believe it is a ground loop issue necessarily.

        Hey nick

         

        Thanks for the reply.

         

        When I play my strat through the pod and it sounds fine however when i plug in my acoustic theres some crazy squealing sounds, hum and feedback notably on the heavier amps and effects. I'm wondering if its simply the battery for my pickup going flat or maybe the pickup itself is faulty. My acoustic is a Cole Clark with a dual input Piezo type pickup that is positioned under the saddle.

         

        Does this type of acoustic pickup or acoustic electric guitars in general amplify humming when playing on hard rock or metal presets etc, or should the sound quality be just like the strat? Even some of the acoustic presets in the pod produce hum when i use the acoustic.

         

        Thanks

    Hi,

     

      It's possible that the pickups in the acoustic guitar could be an issue. Does the acoustic feedback easily with another processor or amplifier?

     

    Also, have you tried  a different guitar cable?

     

      Thanks,

      David

      Hi David

       

      I get feedback when playing through a BOSS BR1600CD multitrack notably on heavier effects etc.

       

      When I run it through a marshall amp with no overdrive its ok.

       

      I contacted the maker of my guitar and here is their response.

       

       

      Plugging directly into a POD will hum every time with a CC acoustic/electric, our pick up signal is too strong for them. PODs are designed to alter sound and make bad pick ups sound good. If you plug your CC into a PA or powered speaker, as it was designed for, and then run that into the POD it should be fine, or you could get an impedance box, makes the signal weaker, in between the CC and POD. Being that it is an acoustic instrument you will have feedback issues with high gain and heavy distortion effects, you could put a feedback buster in and that should help. I assure you there is nothing wrong with the guitar, it just wasn’t designed to be used as an electric. I do use some effects on mine live in different situations, but I use only Boss OD-2 overdrive and a crybaby wah as they seem to not feedback anywhere near as much as amp modelling, multi effects units.

       

      I might try the impedance box or feedback buster. However I agree with them that the acoustic wasn't designed to be played like an electric.

       

      Thanks for your reply
