Hummmmmmmmmm.........Unwanted

Jim Eller · From: Kodak, TN (Michigan transplant)

I have a Lawrence 710 pickup mounted in my Emmons SD10 that seems to have developed a hum. Or at least I've never noticed it before.

I have the pickup connected directly to the jack in the end of guitar and eliminated the little tone control thingy.

I have run it direct from the guitar to two different amps with the same results.

I have checked the wiring and it seems to be ok.

??????????????????????????

Thanks,
Jim

IF the guitar is connected to two amps at the same time, It will probably hum.
In the old days we would lift the ground of 1 amp by using a three prong adapter and not using the green wire or ground strip.

It worked, but dangerously! Don't do it.

Go to Furman Electronics on the internet.They have a gizmo that will solve your problem safely. About $50?

Do a Forum search on Ground loops, Grounding, hum.

Make sure you have a good "instrument" cable. I've seen short "speaker" cables sneak in the loop sometimes. Cord Gremlins???

Thanks guys.

Only using one amp (NV112) and the cables are George-L's.

Do these "hum eliminators", do anything for the single coil hum? Curious...., Or are they mainly for ground hum problems?

Jim Bob, there was a pretty extensive thread on the Electro Harmonix Mum Debugger a few months back. The
reviews were mixed but mostly favorable. I bought one. It definitely tames single coil hum, but with
a slight effect that could be described as a mild,
random phase, which may not be noticable in a loud situation. It is for sure an improvement over having to live with the annoying buzz all night.

Let me add this to the mix.

I have tried this guitar on two different Nashville 112's. It hums in both but worse in one.

I plugged it into my Nashville 400 and it is relatively quite.

And................. as a surprise to me. The pickup is the original Emmons pickup. I didn't realize I had changed it back some time ago. I apologize to Bill for that mistake.

But the problem still remains. It hums with the amps I use to do gigs.

If it's an original Emmons pickup it's a single coil pickup and the single coils are noted for having hum problems. And in this case what you are hearing is "normal".

There are some things you can do to help minimize the hum such as placement of the steel VS the amp, poximity to AC power lines, etc.

But if you can't "live" with the hum, you will need to replace the original Emmons with a humbucking pickup.

Thanks Jack.

You always have good advise.

Thanks Clyde for replying. Smile

The 112's occasionally have a bit of hum in the reverb and you might try cutting down the reverb in the 112 to see if that helps. I'm only suggesting this because you said the hum was minimal when going thru a 400.

Thanks Jim, I'll try it.
