EMI extraordinaire
I have a cheaper Hofner Icon cavern "Beatle" bass that was in need of some TLC to setup. I figured that while I had everything torn apart I'd replace the cheap pc board wiring harness in the body cavity. There was underlying finish damage, so I elected to use a spare bit of plate I had leftover from another guitar project.
I rewired everything according to schematic and then plugged her in and bam- I was hit with instant hum! I rechecked all my wiring and component values and still it lingered. Moved with switch movement and volume controls. I went back to pictures collected on the internet and it looks like the only thing I am really missing is a metal plate to mount the volume pots and switches to. All the older examples appear to have this. Duh!
My question is what can I use? The cheapest thing would be aluminum sheet metal pieces they sell at the local hardware store for flashing. But this seems to thin. Should I just scrounge around or cut a thicker bit of aluminum?
I also assume I will have to ground it to the back of a pot?
Here is the color scheme for the body wiring on the bottom- (tailpiece ground - yellow),(p/u - yellow),(input jack - blue),(p/u - red)
Apologies! Image quality not the best, I can take a better one with cell I think if it helps
