After what seemed like an eternity,I have finished building my 8 string lap steel.It's a real "Stringmesster".Everyone at my local music store seemed impressed.I even seem impressed.But it hums like a S.O.B.Is there any thing that can be done about this besides scrapping it and selling the pickups on Ebay? |

Tom; several things to check pal.
Did you put(one side sticky;other side aluminum foil) underneath the pickups on the wood??? Also can you describe what you have as far as the wiring??? meaning the pickups are wired to what(+&-)and what you have in line to the input jack(like volume pot; tone pot..capacitor..ect)and how they are soldered together.....and if your using an extra grounding wire from the pot or input jack and where you have it affixed.??
Sorry for all the questions; but I can as well as others help you solve this dang quickly with that info.

| As far as I know,there is no foil under the p/u's,which are soldered to a balance pot rather than a blend pot.There are no vol. or tone pots,I use a vol.pedal.The p/u's and pot are connected to an input jack.There is a ground wire on the pot which will be affixed to the bridge.Would it be better to use copper foil under the p/u's and on the sides of the cavity.Thanks for the advise. |
