so the bass /treble controls go when the filter and Q switch are installed ?
 Thanks for all of the information everyone. Please let me take a moment to tell that I feel that I've come full circle in regards to basses. When i was a kid in the early 80's I wanted an Alembic. After 25 years of playing a particular makers very fine basses I came back to alembic; It felt like coming home...
 
Thanks again..

Here is a picture of my epic

I am going to order the filter with the 3 pos. q switch. will there be any soldering involved or are these connectors all snap-fit ?
 
thanks,
DZ

Sorry, I just reread Mica's post about solderless connections...

The Filter and 3 position Q switch are on the way !
 
anyone interested in an A/B test of electronics on this once the filter is installed ?

thanks for the info mica, sounds quite reasonable!

The Filter and Q are in...but the results are poor...
 
I do not not know what i could have done wrong.
 
Whe ni first plugged the bass in i had no response. After about 30 seconds i got some volume.
 
Now, There is very very little volume and what seems like zero function from the q switch.
 
Any ideas ?

The circuit board is probably touching the side of the control cavity, and the signal is shorted out against the conductive shielding paint. Try touching the pins with your bare fingers, while plugged in: you will still get the zooming sound.
 
Move the circuit board around GENTLY so that it no longers touches the side of the cavity.

I looked at that; the only thing touching the control cavity is the insulated wire coming from the pickups to the board. I tried a new battery and that made no difference.

help?

Try posting a picture of the installation.  Maybe someone will spot the problem.

Maybe you put one of the connectors on the p/u leads on backwards? The receiving end budges, so you could probably have managed to do that.
 
Anything else that would cause the signals to be out of phase ...

 I do not think it is possible to puts the leads on the wrong way. They = have those little locks that snap fit to make sure the connection is = made.

 I will do that; good idea.

The little locks that snap-fit may have been forced by someone in the past ...
 
Let's have some pictures.
