phase switch without series mod?

I was wondering if it's posible to make the basscut switch into a phase switch if the pickups are wired normally (parallel)
and if so.. is this all I have to do?

or is this a stupid idea and will make my guitar explode and burn down my house?

I once added a "phase-reversing switch" on the middle pickup of my Strat. When two pickups were in parallel (positions 2 and 4 of the selector), the output was lower, sound was rather shrill, lots of highs, almost no low frequencies ... I guess it can be useful to play a grunge solo with lots of fuzz

... but on the whole I found it a waste of place on my guitar for a more useful switch. So I rewired this switch to be a on/off switch for the neck pickup, allowing much more useful stuff like 3 pickups in parallel (very airy) or Tele-mode (neck & bridge pickups in parallel).

So it's not a stupid idea, but from my experience not a great one either; your guitar and house are safe though.

Let me add that the pickups in a Jag are not as close as a pickup pair on a Strat, so the "out of phase" effect I described above wil probably not be as strong as on my Strat, maybe you can get a useful sound out of it. Anyone tried it on a Jag and like it ?

Hmm, I just checked it out, but it's not so much an phase switch as it is a kill switch now

when it's in the down postion..the guitar is completly turned off one way or another
Getting the feeling I've done something wrong, but I don;t know what..
could it be the wires I used? I found them in a bike-repair-kit

they're just standard normal electrical wires

It's not your wires, it's your wiring

... I should have checked your drawing more closely, it indeed is a nice kill switch.
However I don't have a proper drawing software at hand; when I'm home I'll draw you one unless someone already has.

First, a reminder of the inner wirings of switches :

Now, here's how I would do it :

alright, thanx

the hotwire from the neck pickup is going to the upper switches(as a white wire), THEN from the upper switch to the lower ones(as a orange wire) right?
cause otherwise it would not be connected to the 50K neck switch.. as I see it..

I'll try it out, I'll be posting it later wheter it worked out swell or not

Absolutely, what I call "Neck +" is going first to the rythm circuit, then comes back to the pickup switches, so that's your orange wire all right. Sorry, I forgot the Jag had also the rythm circuit of the JM (I own a JM but no Jag).

Drawing corrected.

oke yeah I figured that the orange wire should go on the top lug instead of the off side

right now I'm trying to find the grounding wire from my pickup...it should be somewhere on my volume pot...but wich one?..there's like 5 black wires there :-\
Oh well...i'll find out wich one..attach it to the switch lug and check out if it works..then you can adjust the drawing one more time

Delete "untested"

Yes, the Jag has almost as much wiring as an Airbus.

hahaha. yeah maybe even more

and I wish it was as clear as the schemetics, but it's total chaos

kinda was going for just a minor little mod and didn;t have to unsrew the pickgaurd and al the strings and remove the bridge and so on, but there was no other way.. oh well

but hey, I found the wire, found out it was to short to reach to the switches so I extended it..attached it, and that was the final wire
so I put everything back into place, and tested it out
when in the up position it all sounds even brighter then the jag pickups already do and way more trebley
everything works perfectly and I really like how it alters the sound
so for anyone else who doens't really use the bass-cut switch, this really is a cool mod

blah blah blah
and many thanks to haddock
