I already have my neck pickup wired to a DPDT On/On switch as coil split ..I'm adding a GFS Crunchy Pat to bridge position..Do I have to use 2 switches to coil tap both.???Can I hook both humbuckers to same switch??If so..how??Right now I have one end jumped together and coil tap wires to middle lug and other end is ground,,Do I just unsolder the jumped lugs and hook bridge coil tap wires to other middle lug ?

Strat, I'm sorta shooting in the dark a little here, so hang on for some other input - if'n ya knows what I means. Nevertheless, my first thought is that you can/should either use another 3-way switch or a push-pull. If the same 3-way can be shared by both, then it's a question of whether you will be bothered that you will have no way of individually controlling volumes on either humbucker. If that's okay, then wiring them both to the same 3-way switch may work. Recalling what you did to get the coil tap to work for you before ( guitarnuts2.proboards45.com/index.cgi?action=display&board=wiring&thread=3447&page=1 ), if you just duplicate that (i.e. replicate it for the new pickup) it may work ... again, I am not sure about that though. Assuming you have a dedicated pot for the new pickup, maybe you would be better off going with a push-pull so that you have coil taps with each pickup, but are still able to individually control the volume of each pickup. FWIW DD

Strato- No, you could theoretically wire both pickups to the same switch. But you're going to be seriously limiting your options if you do so. You would only be able to switch between "both pickups full HB" or "both pickups coil split". And assuming you have some type of selector switch to switch between B and N pups "downstream" of this DPDT, it would no longer switch between the two pickups. Assuming you want the ability to have only a single pup active at a time, you're going to need either additional switches, or a more capable switch than your current "on-on" DPDT. If you think in terms of the signal chain inside your guitar, you will see why this is so. The signal starts at your pups, and goes to the out jack. Components along the way (V and T pots, other switches. etc.) are limited to processing only such signal as they get from components further up in the chain. If the issue is that you're trying to not add any additional switches, it's probably best to post a diagram of what you've now got, together with a description of what you want, and we can then see what switching would be needed to achieve your aims. And DD- Per his post, he only has a DPDT "on-on" switch, not a three-way. Our posts overlapped here, but the bottom line is, he's going to need more switching capabilities, whatever they may be.

So he does ... I don't have a clue where I got three-way from. Sorry about that. DD

You didn't say you don't have a 3-way switch somewhere in there, either. While I agree that it would be severely limiting, I can't figure out why using just the one switch for coil splitting on both would get in the way of your pickup selection or seperate volumes. Is there something weird about the way this switch works that makes it any different from something like a DPDT push pull? What the heckbuckets is going on around here?

Let's review. You have a DPDT switch used to coil tap (coil short) one of the coils on the neck humbucker. You would like to use just the DPDT switch to coil tap (coil short) both the bridge and neck humbuckers (assuming that the "GFS Crunchy Pat" is a humbucker - I'm not going to look it up). If this is all that you want to do with each humbucker, you can use the same switch, use one switch pole for each humbucker. Each pickup will be separate from interaction within the switch, but both of course will be either in humbucking mode (series) or single coil mode at the same time. I have no idea what you are describing regarding "one end jumped together" and the "jumped lugs". Look here. You'll probably find something. www.seymourduncan.com/support/wiring-diagrams/This has two humbuckers with a common DPDT switch for a coil tap (coil short) on both in unison. www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=2h_1v_1t_3w_1pp

Well since stratotak hasn't returned since that beginning post, it's going to be difficult to solve this wiring scheme. I was curious why the coil cut switch is a DPDT (as we know you only need an SPST). Also, if he wants coil cut options for both pickups and if both pickups are on at the same time, there are humcacelling concerns that would be worth addressing.

Yes indeed, and the SD diagram posted above misses the trick. We've been here before, and this is a better version that is humcancelling when you select both coils in coil tap mode: John

Well when I bought the switch I originally wanted it to be series/parallel..and that's what radio shack had..Over the last few weeks I have tried various wrings that I have seen on sites...Ending up with it wired as coil split...Never really liking what I heard..along with the hum .After all the different wrings I tried I didn't like any of the sounds..Even with the pickup wired normally as a humbucker in series.I figured It was to hot a pickup for neck..It measured 12.4 and is Alinco 5..Its a Artec Hot Rails type pickup...same thing as a GFS pickup.So I figured it was not a good pickup for the neck...It was just to damn dark and wooly for my taste...So I was planing to replace it in future with one of GFS Lil Killers ..but get the 6k one...Since my bridge pickup is 10.5 I thought Id get a hotter bridge to balance it out with the one I have in it know..Hence the Crunchy Pat's at 14k..Its pretty close in sound to Dimarzio Super Distortion..and has good reviews on Harmony Central..And from clips on you tube It sounds pretty close.I wanted to use the same switch because I didn't want to drill another hole again and have another switch...But after I posted last night I felt like trying something again..So I unhooked the switch and wired pickup wires in parallel..not using switch..but just connecting wires on pickup. And I liked it..Its dint sound like that when I wired it with switch as series/parallel...So left it permanently wired in parallel..It sounds better wired parallel ,at least for this situation.So now my plan is to use switch on Crunchy Paf when I install it and use it to coil tap it or maybe series/parallel..I mean I drilled a hole in guitar and have switch in it..might as well use use it..lol...that's the plan now..but who knows ..that might change ..lol..But that brings up another question??Why does it sound good with pickup wires connected as parallel..but with a switch it didn't sound like that..??Switch is a $3 Radio Shack switch..would a cheap switch make a difference in sound..??

Oh..forgot to add my setup and wiring ..Basically its nothing complicated ..A Hamer California Import from 1993...like this one..mines not red..lol. Switch is a Fender brand 3-way..same thing one a Tele.. Neck pickup is a Artec Hot Rails at 12.4k Bridge is a Powered by Lace 2 wire humbucker at 10.5k to be replaced with a GFS Crunchy Pat And a DPDT ON/ON switch from Radio Shack..part number #275-614 Its wired exactly like this..other than On/ON switch

After looking at JohnH's diagram, I stand corrected, hadn't thought of doing it that way. But he's still looking at both pups split, or not.
