Hum sound on Luke guitar?

[thisispastrami]

Hey guys, is any of you have experience a little hum sound on the Luke guitar? I bought my guitar in December and I really love it, its the perfect guitar for me, but it have this hum sound. It's not that big, but when im recording there is that start to make me mad. Do any one have experience this? If so, how can I repair it?

Is it just the Luke that gives the hum? Have you tried your other guitars through the same rig?

How are you recording? Is it via a mic'd up amp, or into a simulator and then on?

What are you recording on? Is it to a laptop, or a workstation?

What happens with the guitar when it's just plugged straight into the amp? Have you tried the amp with nothing plugged into it, to see what the background noise is there?

Also, have you checked the cables that you're using? It could be that they're picking up interference, especially if it's an electrically noisy environment (eg, flourescent lighting)

There are many things that it could be, b ut to check the guitar itself, the easiest thing that i cna think of would be to try it at another location, through another amp, then at least you can isolate if that's the problem or not.

Hope this helps.

Just a quick thought.

Have you checked the 9v battery to see if that's ok?

yeah was thinking about this one too. a low battery may generate some hum

Are you using the piezo when you record?

(i.e. using a stereo cable, or two mono cables simulataneously... even if you're not actually recording the piezo output.)

 

[thisispastrami]

Yeah its only with the Luke, and yes I have change batteries like 4 times already. I mostly connect to a PodXt and it gives me this hum, but its only with the Luke.

Does the hum get worse if you take your hands off the strings? Could be a grounding problem.

Is it loud enough that you hear it on the clean channel? Or just your usual RF noise made worse by gain?

(I actually find I get noise through the EMGs I've had. I seem to have a noisy house, RF-wise and they always pick it up.)

Try a long cable and do not come to close to the pod. Sometimes EMG pick up some noise from gear. Mostly monitors but try it.
Hope this helps

wow beej answer in the same minute

 

[Jimmyb]

Ok.

Well I don't have a Luke, or a POD, so I'm probably not the best person to comment on this But..

It may well be the case that the output from the Luke is 'hotter' than that of your other guitars (ie, because you're using an active system, the signal output could be higher).

Is there a way on the POD of attenuating (turning down) the input level? You should be able to set it so that the noise floor is reduced, but obviously you'll have to make sure that the output level is matched accordingly.

Maybe someone who has both the pieces of equipment will be able to tell you more?

 

[thisispastrami]

Actually I havent noticed if the ground gets worse without my hands on the strings, but yeah the hum continues even with the clean, not soloud but its there.

 

[thisispastrami]

yeah jimmy, but man i appreciate your help anyways, and by the way you should try a Luke, for me the best guitar ever

 

[SteveB]

Let me ask again if you're utilizing the piezo.. that can introduce hum sometimes if the two signal paths (magnetic and piezo) are connected to two different grounds in the building.

 

[thisispastrami]

oh sorry for not answering before, but no im not using the piezo...

Maybe it's humming 'cos it doesn't know the words!

Wait, this is the musician jokes thread ?

Do you have a CRT computer monitor? These make most guitars hum like nothing else!

 

[thisispastrami]

Yeah i have one, but on saturday i was recording on a pro studio no CRT monitor and there was when the hum sound make me mad, maybe it's the Pod I dont know...

 

[Jimmyb]

I reckon it could be more a case of the input of the POD being designed to take a passive guitar. Then when you feed it with the active out from the EMG's on the Luke, it may be that the signal is a little 'hot' for it.

A longer cable may well help, as this will effectively attenuate some of the signal from the guitar. However, when you have the longer cable, it may well be more prone to interference...

I can really reccomend the cables by this guy although he's not the cheapest maker around.

I get some hum from my pod also.
Maybe I'll try a longer cable.
