Topic: Strange sub-space field anomaly when turning old lap steel |

Maybe some force field physicist can help me….
Acquired one of the older Oahu Tonemasters. Tone full!
I redid the ground wire as it was humming a bit (probably typical for these old birds.). Got it pretty quiet now… BUT I notice that if I lift it up and turn it 90 degrees (like I was holding it like a typical guitar) the hum basically vanishes. Mind you, it doesn’t matter if I hold it against my body or out in space, it’s almost dead quiet. If I turn it back flat, as if on my lap, the soft hum returns.
I have no neon lights, microwaves, Tesla coils or alien crafts in my house.
Any ideas?
Thanks and happy day of celebrating the working man and woman

Fluorescent or LED lights perhaps? I know they can sometimes be noisy...
I have a few Oahu Tonemasters and the single coils in those really do pick up the noise. I gigged with one and in some venues, I just had to ride the volume control and shut it down in the quiet parts... others it wasn't so bad.

Where is your cell phone during this problem, If it is on your belt or laying near could be the cause.
A cell phone laid on some amps. can cause many problems. |

This behavior is quite normal (common usage). The orientation of the pickup relative to the electromagnetic disturbance (normal, i.e., perpendicular or orthogonal incidence vs. parallel incidendce) can make a very large difference in how much of that disturbance is transmitted through the pickup. This is one of the problems I have with using single coils on a steel guitar situated horizontally - on a stand, lap, or whatever.
When I have a guitar with single-coil pickups like a Telecaster or a Stratocaster, I can almost always turn and/or change the orientation of the guitar and find a reasonable null for the noise. I have never had much luck with a steel guitar. |

Ahhh this is good info. I play in the same place when I play. Almost palindromic. I shall play in other zones and take notes
