I have just picked up a great MIJ Jazz Bass circa 93/94 but it has a unique control layout which I am having trouble getting to grips with. Cannot find any other like this or any info to help me out. It has the standard 3 pot layout with the addition that all 3 are stacked pots. There are also 2 toggle switches - 1 under first pot and 1 under 3 pot. The top pot on control one seems to be overall vol control but cannot work out rest. Obv there is active/ passive switch but the controls dont seem to be the usual vol/vol/tone in passive mode, in fact any no eq controls in passive at all. Also the active eq is v confusing, not sure which is pickup select or blend etc. Any ideas or help would be appreciated
Serial No is O 067896 if it helps?
I have included pic which shows all controls except toggle switch under 1st pot.
