I have done a search and come up with plenty of descriptions of what is there now the question is where are they located on the bass? Fender is no help at all.
ok the knobs near the bridge are volme and tone the top switch on the lower horn is neck pickup on and off and the switch under that is bridge pickup on and off and the bottom switch on the lower horn in series parralell the top switch on the upper horn is active and passive and the two below it wich only work in active moder are treble and then bass hope that helped and if you ever need more jaguar help you might get quicker responses in the jaguar club http://www.talkbass.com/forum/showthread.php?t=371287&highlight=jaguar+club click on the pick for more detail
