    does anyone have a diagram for it?
    does anyone have pictures of how they have executed it with the switches/wirings etc?

    does anyone have clips or experience with it?

    I have it on one bass: used a push/pull on the bridge volume. It's a really great mod: adds a thickness to a J that is not attainable with stock wiring. The little volume boost is cool, too.

    That's the one I used, except I put the switchpot in the tone position.

    has anyone done it with a mini switch? instead of push pull on the tone knob or bridge volume knob?

    I had one on a switch in a MIM Jazz. It did require drilling the control plate and routing the body to fit. But I did prefer that to a push/pull because it felt a little more solid, less likely to be bumped. Wiring is the same as the push/pull.

    Edit: bad cell phone pic attached. I no longer have this one. But you can see the switch on the plate above/between the two volumes. It's a refinished MIM body, so there was originally wood under where that switch is placed.

    I used a switch on an old P bass years ago. Worked the same, but did put another hole in the pickguard. Had I known about push/pulls, I would have done that in order to make reversing the mod clean.

    Do both vol pots still work when switched to series?

    No. You have to pick one to be the volume while in series, and the other will do nothing.

    My neck volume becomes the master volume when in series mode. It's closer to manipulate than the bridge volume. The push pull on the bridge volume also allows to not mess with adjustments since I tend to leave the neck volume full up most of the time.

    Bummer. I used a schematic to wire for series only, and both vol pots still do their thing.

    Hmm, mine didn't, at least. I know there's a few possible ways to wire it up. I don't remember exactly how I did it, but in series, the bridge volume was inactive.

    Do you get a change in tone and volume when you switch?

    This exactly. I've installed 3 of these, including on my current parts Jazz. All three were wired with a push/pull pot according to the schematic on the SD site. It's such a cheap and easy mod and it's such a neat tone to have access to, that I consider it pretty much a necessity on a jazz bass.

    The whole point of series is that the two pickups basically become one sweet humbucker. There's not really much (any) reason to control each pup individiually in series mode.

  15. As said above...the neck volume on mine is the master for series volume. 003.JPG

    Big fan of Fender's S-1. Can't even tell there is a switch!

    A friend of mine installed a BQ V12 tone pot with serial/parallel switch a while ago, and it got me very enthusiastic. :)

    That switch is a really nice addition. Highly recommended too. The V12 pot as well. Gives you 12 very usuable tone choices.

    I'm assuming this would sound like my Jag Deluxe series/parallel switching?
