I just thought I would mention something that has frustrated me up until I discovered what the problem was. I had wired a guitar up using 2 humbucker pickups, 1 Volume pot (cts), 1 3-way selector switch and a jack input socket.
All seemed well when I checked the pickups using the screwdriver tap test but there was quite a load constant buzzing noise, very annoying. I checked and checked and checked and checked my wiring work and it was definitely correct. WTF?
I then thought, right, take a break!
Then!
As I turned off my soldering iron, the buzzing stopped instantly and all my wiring worked perfectly! Ahhhhhhhhhhhhhhh............??????
Watch the video for a demo.
Make guitars, not war 🌍✌️🎸
I was getting some really loud buzzing recently when I plugged my lovely new bass ( https://guitarmaking.co.uk/community/showcase-bass/short-scale-30-walnut-bass/#post-838) into a Focusrite audio interface. Really annoying. I checked the wiring, turned lights on and off, adjusted various gain settings....
...turns out it was a dodgy guitar lead.
