I have a three knob tele from doing extensive mods and due to liking the ability to mix the two in parallel and series.
Recently changed the blade switch from a super switch to a standard 5-way using Craig Anderten's wiring www.tdpri.com/wiring5wayStrat.htm (second one down) cause at the time I had a TV Jone's TV'tron and wanted that Gretsch tone switch sound and utilize the Broadbucking feature while in series.
Both volume pots are wired independent to the switch.
When I went for the neck with tone cap, it sounded way too bright like i had a short or something, turning the neck vol down didn't do anything...
Ditched the TV'Tron for the matching neck pup to the bridge SD Broadcaster. Same results...
Took measurements with a meter with the knobs cranked up and down and noticed the following, btw, neck dc is 7k1 and the bridge is 7k7 with 500k/250k volume pots
NV BV value
10 10 7k1
10 0 3k8
0 10 157k no sound
0 0 7k7
even got the same readings when the control plate was lifted, plugged it to my practice amp and when i was rotating the knobs, noticed how it got brighter as i lowered the bridge volume and could only concluded it was going out of phase. Normally with just one volume pot, the bridge pup would short it self out leaving just the neck and cap, with two volumes, the bridge volume is in the way and puts the two pups parallel out of phase.
This was the first thing I thought of and always wanted to try from Borsanova's 'Only one switch for humbucker & out of phase' wiring
But the good thing is that you can also use your controls for further effects. So put the selector in position 3 (neck alone) and turn the bridge volume to zero and you'll be surprised how your sound turns thin and sharp (allowing to emulate even some Shadows tones). In fact this position creates a reverse current in the bridge pickup and puts both pickups in parallel out-of-phase. You can also use both volume (and tone controls) to mix the signal. Put the neck volume to 8 or the bridge volume to 2 and you'll see how your sound turns fatter as the other pickup starts to prevail.

At first with the TV'tron and SD Broadcaster i had an issue as the TV pup is OoP naturally to the SD pup. Pulling the phase switch changed it. Left it that way cause it was nicer sounding to switch straight over to OoP series and parallel. Changing the neck pup let me hear what was really going on in that position. I get that extra sound!!
If you add a .047 cap to the switch's common lug where the B- is and ground, you'll change from humbucker to full Broadbucker effect, or a deeper treble roll off for n,n+-b,-b
I suggest switching in a cap instead of leaving it hardwired to the blade switch is you don't want too much treble roll off in that position and not enough when in series Broadbucking mode.
Throw in a phase switch for the neck using a .01 cap in series to warm it up it it just really adds to the versatility.
(-Nx.01)+B, neck w/10% less bass, and in the new position (Nx0.1)+B, bridge is back in phase now.
So far the only draw back is when switching from the new parallel OoP to series is you may have to roll you bridge volume back up since it was 'reversed'
