Have it wired using the white as hot and following the Pibull 2 Humbucker 4 pot wire diagram. The schematic shows the output jack wired as ground to the long pin, hot to the short pin. There are 2 short pins, both the same height. Just use one or are the 2 short pins connected? Thanks
There can be some variation with that type of jack as to which lugs connect to what. Recently it seems on the stock jack the two shorter lugs are the ones needed for a mono connection like on your IB-5 (often the shortest lug is hot and the next shortest is ground, if there's any height difference). If you have a multimeter use that to test which lug connects to the lead's tip and sleeve.
If you don't have a multimeter connect a lead to your amp and plug it into the jack at a low'ish volume. Touch one lug at a time with your finger tip, if you hear a hum from the amp then that should be the 'hot' lug. Then, while still touching the hot lug touch the other lugs and if the hum stops then that should be your ground lug. It's a crude test, but should work.
Thanks Scott, will give that a go with a multimeter. The long lug appears to be connected to the sleeve (this should be ground) the other 2 (must be tip and ring) are exactly the same size. So, it's just the tip and sleeve for the IB5. Will let you know how this turns out.
Wellllll, all wired up. On the new jack, you have to test with an ohm meter. Both short lugs are the same size, one is hot, other ground, long lug not in use. Only problem is that if you wire your pots per the schematic, align them as shown, and wire them as shown, all volume and tones are backwards. Clockwise to decrease volume. Guess I should have checked them with a meter prior. When I get done, I will try to draw a new schematic with correct orientation (as your looking at the back of the bass) for a 4 wire Humbucker. Hope to finish up this week.
