Correction.
The 1/4" jack is wired stereo and it is working correctly. (I was inadvertently using a mono/ts cable previously)
All positions of the pickup selector switch work as they should when using the 1/4" jack.
Position 1. Neck pickup on, bridge off
Position 2. Both on
Position 3. Bridge pickup on, neck off
Position 4. Both pickups off / standby
Volume pots function as they should, lowering or raising levels respectively.
The 5pin jack is totally wonky.
As mentioned previously both pickups are coming through on all settings of the pickup selector.
Position 1 = Neck(bass) pickup strong and lower level signal from the bridge pu.
Position 2 = Both pickups, strong signal from both.
Position 3 = Bridge(Treble) pickup strong output and lower level signal from Neck pu.
Position 4 = Low signal from both pickups.
In addition, the volume pots are not functioning properly when used with the 5pin jack. Signal passes regardless of the level of corresponding volume pots or setting of pickup selector.
This is a weird one!
Thanks everyone!
Mica, I just sent you photos of the jacks. Thanks
