I suspected your bass was old enough that they wouldn't be included. It's only been a couple of years that we've been adding them. Let me know how it works wonce you get them installed.

Does this also apply to Q switches on basses with Europa type electronics?

Hi All,  
I am currently having this same problem with my neck Q and I just wanted to know  
Should I get 1/2 Watt or 1/4 Watt 1 Meg resistors?  
Does it matter?
thanks

Either one will work fine.

thanks ...

For the Europa, here's the placement for the 1Meg resistor:
 

I finally took the backplate off my Custom and sure enough, no resistors.  I installed two 1 meggers and sure enough, no more pops.
Thanks Mica!

Well I took my soldering iron to the Alembic this morning and installed the 1 meg resistors as you said Mica and sure enough no more clicking from the switches.
 
Thanks for that.

Hi Mica, I've just started playing the bass again after a run of guitar playing gigs.
I notice that the modification for fixing the clicking sound has stopped the clicking but also it has stopped the function of the Q-switches.....
 
When I operate the Q switches there is no change in the sound at all?  
 
Any advice?
 
Jazzyvee...

The difference in sound is not evident by simply flicking the switch, it affects the attack portion of the note only. Compare a passage you are good at repeating with the switch on and off and listen to the attack of the note.  
 
There won't really be any difference from just flicking the switch across a sustained note.  
 
Perphaps you can post a picture of the modification you made? Thanks.

Ok, I will try that and see if I can hear any difference. If not I hope santa gets me a digital camera for christmas so I can send you the picture to check my soldering :-)

You hear it better by spinning the filter knob across a sustained note than by flicking the Q switch.

There is no difference in the attack of the notes when using the switch. There is a difference in the tones available when sustaining a note and spinning the knob.
 
I'm gonna remove the resistors and check the sound again.

It sounds like you may have installed the wrong value resistors.  If they were 1 ohm for instance, instead of 1 meg, it would be as if the switch was always in the on position.

Well that did cross my mind although I did go to a respectable electronics store and ask them for the resistor rather than try to remember the colour coding system.
 
But I will check it asap as I have a gig next Thursday with it.
