I've had this bass for about a decade now. It was played regularly up until about a year ago until I switched back to jazz basses (mainly because I just wanted a change).
Something always seemed odd to me about the controls, they seemed backwards to me.
(http://club.alembic.com/Images/16271/84111.jpg)
Going by the photo above:
Pan knob: Rotated so the white indicator is pointed towards the neck, I only have the bridge pickup on. Rotate so the white indicator is pointing towards the bridge and the neck pickup is on.
Neck Filter knob pointed to in the photo, actually controls the bridge filter on my bass. Bridge filter knob pointed to in the photo actually controls the neck filter on my bass.
Neck Q switch in the photo controls the bridge pup on my bass, same for the bridge Q switch on my bass...
I thought I was either crazy or just smoking too much dope, but I spent the past ten minutes playing around with this and it's clear to me this how my control layout works.
Is the photo backwards or are my controls backwards?
Oh, and the LED switch turns on my coffee maker!
On a side note, love the sound of this bass, and I loved playing it when I had it in rotation but after playing jazz basses exclusively for the past year I have a hard time going back to this bass. Scale seems to small now, and the neck dive is more apparent to me than it was before.
I might be on the lookout for a medium scale balance K in the future.

I think you're going to have to elaborate a little Greg. What exactly do you mean by 'backward'? On my sig they all increase in 'whatever' when turned clockwise apart from the pup balance which increases towards the neck pup when turned clockwise from the detent and increases towards the bridge pickup when turned anti-clockwise. The bridge filter is nearest the bridge pup and the neck filter is nearest the neck. Likewise the 'Q' switches. Exactly what I'd expect from any guitar control.

just updated my post...sorry..hit submit before i was done.

Ok. That makes more sense. Your filters and 'Q's certainly seem to be in the wrong place. Mine are as per the labels in the photo. I'm not sure about your pan. If you turn it clockwise from the detent, does the bridge pup increase in volume? To me, this would suggest that the pickup plugs may be in the wrong sockets. try swapping the pup plugs and see if it sorts out the problem.

When turned clockwise fully, the pan knob leaves only the bridge pickup on...CCW leaves only the neck pickup on.
Where are the pickup plugs located? Is it literally unplugging and plugging back in thats required ?

really easy to swap. there's a picture if sorts in this thread... http://club.alembic.com/index.php?topic=24048.0
just switch the two thick Grey leads with brown plugs.

can't see the photo Greg?
Edit. Shouldn't need to see the photo..
There should be a 'ferrite bead' - round lump of metal with the two grey pickup wires looped through it. Follow these to the brown plugs on the circuit board then swap the plugs.

Afraid not. See my earlier edit though. might help.

weird...hosting it through facebook..here is the public link, pretty sure what i have circled is what i need to swap.

It's probably a security thing - browsing at work and they lock most social stuff down (apart from the club luckily).
managed to browse on someone elses phone ... Yes, it's the two plugs circled. just swap them around.

Yep, those are the ones. Most likely yours looks more like this:
(http://club.alembic.com/Images/411/110175.jpg)
The pickups connect behind the blue trimpots on the Filter boards on these.

It's the white and brown plastic connectors that need to be switched with the trimpots?
Honestly I don't do electronics and its not readily apparent to me that those are easy to remove and switch without breaking everything. Do they just pull out and push back in or is there some kind of restraining device holding them in place. The circuit boards in there seem so delicate Im afraid that if I go in and start messing around I'll break something. I've been meaning to drop it off for a setup so I'll probably have the setup guy switch them around.

Did you buy it new Greg. It's possible a previous owner could have switched them.

Yup..brand new from Bass Central around 2008.
I had always thought the controls seemed backwards to what they should be, but I never followed up largely due to free time issues and the fact that I just dialed things in to get a sound I liked and left it that way.

actually it was easy..they both pulled out with a gentle tug and went back in just as easily...whew...tone controls work as they should now.

Glad you got that all sorted out - that would drive me nuts! Wonder how they got switched - I find it hard to believe that it left the Mothership that way.

Mica can chime in I guess but yeah Im pretty sure it did. The bass was brought brand new in 2008 from bass central. I can't imagine someone there going in and messing around with things.
Shit happens I guess...one could argue that with something this expensive something that simple shouldn't have happened, but than again it took me almost ten years to finally realize something really was up. I swear though I thought I was crazy or just too high. I must have looked at that photo in Daves sticky over a dozen times the past decade and went "huh?"....

I would have done such a thing as to my mind, the pan pot is now backwards. Clockwise=treble, anticlockwise=bass. But that's just me.

Obviously you are a person who is free of O.C.D. :o
-
Can't you just set the pan knob so the neck pickup is on, then loosen the knob and move it so the white line points toward the neck? That way the clockwise/counterclockwise issue is irrelevant. Turn it so the white line points at the neck and get the neck pickup. Turn the knob so the white line points toward the bridge and the bridge pickup will be on.
Bill, tgo

Hi! We make mistakes sometimes - regardless of expense, it's just humans here. Glad you got the pickup leads switched and all sorted out and sorry if this caused you stress for the past decade.

You mean CDO. Gotta keep those letters in alphabetical order.

I had a similar incident when I bought a used elan. Eventually i managed to get everything in the right place and the controls doing the right and expected thing. I couldn't have survived a decade with things they were on my bass. I think when I asked the seller he told me things were setup like this when he got it from the previous owner. I expect someone previously changed things round to match their own specific needs but it was great to have things working logically.
Enjoy your bass again. :-)
