4way-Twisted Tele-Broadcaster, what did I miss?

I just wired up a new project tele with the 4 way wiring diagram posted here on the website.

I am using a Twisted Tele neck pu and Broadcaster bridge pu.
positions 2+4 sound great, best #2 position ever, IMHO.

Positions 1+3 are lacking, they sound nasally and a little lower outputs.

Any thoughts on where to go to from here?

Nothing from all of the experts here?
I may have some time to tinker today, both positions 1+3 are very thin and bland, positions 2+4 sound great,
I didn't notice if I had hum cancelling or not, I'll need to confirm that, I'll check phase, reversing the PU leads, one pu at a time,

The twisted tele is wired
yellow =hot
black =grnd
green = cover =grnd

bridge
white = hot
black= grnd

If 1 and 3 are your series and parallel positions, I think you have a pickup out of phase.

pos #1 would be the neck PU and #3 would be the bridge PU
pos #2 +#4 should be the series - parallel

I'll assume its a Seymour Duncan, so you likely have an inherent phasing problem between the Fender TT neck and the Broadcaster bridge... Simply reverse the TT pickup ground (not the cover ground) and hot wires to the switch and assuming everything else on the 4-way is correct, you should be ok!

^^^^^^^^^^ This. One thing to remember about Seymour Duncan pickups is that they are 'Out of phase' with Fender pickups. They cannot be combined with Fender pickups (With the exception of the Hotrod 52 AVRI bridge pickup) unless one or the other of the pickups has the ground and hot or the magnet polarity reversed.

pos #1 would be the neck PU and #3 would be the bridge PU
pos #2 +#4 should be the series - parallel

Sorry. Very hard for me to accept that your pick ups sound thin/nasally/lacking individually and sound good combined.

Do your ears confirm those switch position assignments?

To be absolutely certain, connect the guitar to an amp at low volume. Tap on each pick up in turn in each switch position.

As everyone else has said the thin bland sound is sure sign that the pickups are wired up wrong .I had it when I wired a Van Zandt bridge into a tele that had CS Texas Specials fitted as stock .I kept Texas Special neck as per .I reversed the VZ wiring and wow ,away we go .great sound as your should be .

Don't know how 1 and 3 can be bad, that pups are on their own there ???



>positions 2+4 sound great<

Then they are in phase.

upon closer reading,and as noted by sjtalon above, you say that positions 1 & 3 (should be bridge only & neck only, respectively) are the issues, that just doesn't make sense... Positions 4 & 2 should be the series & parallel combos respectively, as per standard 4 way wiring diagrams. Besides the SD/Fender phasing issues I'd reassess your switch wiring. Also, its relatively rare but check the switch contacts -- you could possibly have a dud switch...

Here's a scan of the diagram that came with my Fender 4-way switch. I think it's easier to follow than some of the others online:

Sounds like may have a wire connected wrong, or a cold solder or solder bridge.

I put it in my CV50 with the stock 8.8k bridge pup and a TT neck pup. The series position (4) is very hot, and the other three are similar in output volume.

First off I do want to thank all of you for your help and insight to help me resolve this issue, this trully is a first class group.
Swapping the leads on the neck pickup did the trick, but I assumed something and I would suspect some may make the same mistake that I did.

I didn't read the whole paragraph.

4 way switch with master volume and master tone which is a nice upgrade to the stock 3 way switch. This is the same diagram that Fender provides when you purchase a 4-way switch from them. This mod works best if the neck and bridge pickups have opposite polarity. Here are the switch positions:
POS 1 = Bridge alone
POS 2 = Neck + Bridge (parallel)
POS 3 = Neck alone
POS 4 = Neck + Bridge (series)

I had always assumed that POS 1 = Neck alone, so I was bass ackwards from the get go.

My statement that my "#2 Pos was the best ever" which actually was POS 3, ended up being the twisted tele PU all alone, wow now I see why these PU's are so highly regarded,.

Worst part of this, these PU's have been sitting in my parts bin for over a year!

Thanks again
