YB-4 Wiring Issue

[JimC]

Have you got a little multimeter that does resistance? Superficially it looks as if the right connections are there, so I'd check continuity. Earths especially. A bit more detail on the symptoms would be good too.

Thanks for the note. Before I install the bridge and string up the guitar, I check to see if the wiring is correct by plugging in the guitar and just lightly tapping the pick ups to make sure I can hear it through the amp.

For the individual tests of each pick up, as I turned the volume pot up to max, I could hear the tapping clearly through the amp. However, when I completed the full wiring per the diagram, and tried the tapping test, even with adjusting each volume pot to max, I could not hear any tapping coming through the amp.

As I adjust the tone pot, I can hear the change in frequency so I know that, that pot is working. I have tested the pick ups and each pot with a multi meter and the appropriate resistance amount is shown on the meter.

Hope this makes sense.

I just read this again and realised I may have misinterpreted. So you don't have any volume at all now?

Correct. When I soldered the jack directly to each volume pot/pick up, the pot worked. However, when I soldered all of the connections per the diagram, 2 volume, 1 tone, I get no sound from the pick up. Woltz provided some info to test each pot. I will give that a shot then start to replace wiring if required. Thanks for your help!
