Hello, I got bored and decided to build a lap steel. Not that I needed one but just for the challenge.
I have it all connected (soldered) the way the diagram shows but I can't get the hum out.
The hum is there all the time but gets worse when I touch the strings
I have a input jack socket
pre wired loaded tele bridge control plate w/6 saddles
tele bridge pick up single coil
I have a ground wire from pickup to back of volume pot & live from pick up to pin 8 on ctrl plate.
I also soldered a ground to back of pick up to volume pot ground
a white from center lug on volume pot to negative on input jack
A ground from ground lug on ctrl plate to input jack
This is not a cable nor amp problem as my factory guitar works just fine.
Wish I knew how to post a picture but this is the best I can do,
Any help or suggestions would be great, bob
You getting the 60 cycle hum that all single coil guitars get.?
Single coil pick ups are notorious for picking up AC hum, and perhaps when you touch the strings your body is acting like an antenna in this case. Make sure any lighting dimmers and a computer nearby are turned off, as these are noisy electro magnetic interference (EMI) devices. If all this doesn't help, lining the body cavities where the electronics are with thin adhesive copper can help. Make sure to cover any plastic "pick guards" and ground the copper. This helped on a G & L Legacy Strat that I have. Copper available from Stew Mac.

thank you Frank, I will give it a try, bob
Do you also have a ground wire going to the bridge? This would ground the strings, which is a big source of hum.
