Sorry, i've only shown half of the dpdt switch in the pic.
Thanks for the wiring tip

I've heard you guys discuss 'hanging' coils, where a coil is connected to hot on one end, and nothing on the other (is that right?) I wired up my dummy coil in my strat like this: Does this mean that the coil is 'hanging' when i havent got it selected? How much more hum have you guys experienced with a hanging coil?.... Also, how could i wire up the dummy coil so it doesnt have a hanging coil when not selected? (the switch is a dpdt on/on) thanks!

Hooked the same coil i used for the p-90 up to my Ibanez hardtail strat today. After much fiddling i managed to stuff it under the pickguard next to the bridge pickup, and i hooked it upto the switch to compare. When turned on, It cancels most of the hum in the neck and bridge positions, but increases the hum in the other 3 positions. Tonal change? In short, it takes away most of the great sounding characteristics of a fender single coil....all the sparkly single coil goodness is gone and it just makes it sound fairly flat and 'boring' for lack of a better word. Also is just a tad quieter with dummy coil switched in. Though i can see myself using the dummy coil when playing live or recording.....as i usually just use the neck or bridge Recorded a clip just using the neck pickup.....first take with the dummy coil switched in and the second is just the neck pickup on its own....i'll let you decide which one sounds better. martinrotolo.googlepages.com/dummycoil.mp3Cheers

Mickey - too lazy to put in a switch + no room. But i can safely say that i dont find the tone to be any worse or any better than it was before. In any case, being able to turn up just that little bit louder and have more dynamics in my playing makes it sound better to me Love ya quotes BTW ;D Just tried the same thing on my epi LP which has a GFS hum-sized p-90 in the Neck slot. The coil mismatch was a bit greater this time (the p-90 was about 9k, and the dummy coil about 5.8k), + different coil shape, so the hum-cancelling wasnt quite as good this time. But, with the coil in a very particular position, a similar result - A lot of the hum cut out (is actually as quiet as the humbucker in the bridge...but its a noisy bridge pickup i think).....and i can barely detect a difference in the tone. Cool! Dont get me wrong, it still makes noise...but its quiet enough to keep me happy Now heres my problem: The mounting of the dummy coil. In the bass there wasnt much room for it to move around in the cavity plus the cavity cover was pushing down on it....so i dont think it will move. On the LP, the cavity is deeper and the dummy coil will move around when i move the guitar around. Plus, the 'sweet spot' of humcancelling is a lot smaller. Any ideas as to how to keep that coil fixed in the one spot for good? As fer now its just a very dodgy gaffa tape job Edit: after a few solid test shakes, the gaffa seems to be working pretty nicely. Time to actually play the thing i think! ;D Edit pt2: Neck pickup sounds great. Dream 90 they call it. Sounds like pure blues to me Cheers, gunther

<EDIT:>The topic of dummy coils comes up every so often, hence I have made an Executitive Decision to sticky this thread for easy future reference. gunther has done some positive research and posted his results in a way that most people will probably understand, and then be able to duplicate for themselves..... and that's a good thing. If anyone else wishes to contribute, or ask questions because something is not clear, please do so here in this thread so that others can take advantage of the discussion. UPDATE: Another thread, with a different method and explanation, can be found here: A successful attempt to low impedance dummy coils in an SSS</edit>Since reading lots on this forum i've become pretty anal about instrument noise...almost unhealthily so! But My 5 string bass guitar had been REALLY irritating me. It has a P pickup in the neck (which was pretty quiet of course), and a J pickup in the bridge (noisy as!). I liked the tone of the J pickup but never used it because it was so noisy Was almost ready to pull the trigger on a stacked replacement pickup...but had a moment of inspiration after reading a couple of threads here about dummy coils. I also remembered that i had a couple of guitar single coils that gfs were selling for cheap...the only reason i bought them really. The J bass coil measured 5.36k ohms, and one of the gfs single coils measured 5.43k ohms....pretty good match i thought. Got a knife and pried away the bar magnet underneath. Then i had to cut off the mounting tabs so it would fit in the wiring cavity. First i tried hooking up the dummy coil in parallel with the J...mainly because i'm lazy and i didnt have to solder it in this way....sounded a lot weaker, cutting out a lot of the bass frequencies. Got out the iron and hooked it up in series the next time. The output was the same as the pure single coil..only problem was that there was still a bit of noise. Spent some time just moving the dummy coil around in the cavity and listening, and eventually found 'the sweet spot' where it cut the most amount of hum. Added a bit of tape to secure it in place (also the pressure of the cavity cover seems to hold it in tight) Results: The bass isnt totally noiseless, but i'm quite happy with the signal to noise ratio now. The J pickup is almost as quiet as the p pickup, and just as loud. And the bass is even quieter when both pickups are on (and i like this sound the best) As far as tonal change, i really cant detect any...but them again i'm not a bass connoisseur. Hope that info helps anyone who's interested in this stuff.

I've had to lay some tape down in spots where the hot signal would contact the shielding (output jacks and superswitches)

I've read some complaints on a few different message boards about how switches and complex circuits 'suck tone' One example being the s-1 switch on some strats....Have read that it 'muddies up the tone' The question - Do you think extra switches suck tone? I really cant see how they do... Guess i've answered my own question...but lets hear your opinion

Well i always have a lot of crazy wiring ideas... So i think i need to learn how switches work instead of annoying members of certain message boards for wiring requests ;D If someone could run me through the superswitch (and the normal strat 5 way) that would be awesome. Hopefully i can repay the debt sometime in the future by making wiring diagrams for others

Michael - No, the bridge is a Tapped single coil
The JD wiring Is the neck and bridge in a controlled degree of reverse phase. but i dont know the specifics (help!)

No, i was thinking Neck and Bridge combined in parallel.
Actually i've changed my plan a little!
1. Neck 2. Neck and Bridge combined in series 3. Neck and Bridge (JD wiring) 4. Tapped Bridge 5 Full Bridge

Anyone know how it works and whats so special about the 2, 3, and 4 positions? www.peavey.com/products/browse.cfm/action/detail/item/116158/number/00581620/cat/355/OmniacSeries.cfmBe interesting to have a look inside. And if anyones got a diagram, please fling it my way. I'm keen to try it out on my tele Cheers ;D Edit - Found a thread on the Seymour Duncan Forum: www.seymourduncan.com/forum/showthread.php?t=46917Covers it pretty well. I want to do something similar...but i have a tapped tele bridge pickup. Heres my idea: 1. Neck 2. N + B (JD wiring) 3. N + B Tapped (Parallel) 4. Bridge, Tapped 5. Bridge (full) Anyone wana come up with a diagram??? Cheers Still got some questions about the wiring on the Omniac guitar... * Whats so 'special' about the cap in position 4? * Whats the customized parallel wiring??? If anyone knows, fill us in!!! Thanks

Hi all....a simple one for the pros
Got a guitar here with a humbucker in the bridge and a single coil in the neck, hooked up to a tele style 3-way (master vol, master tone). Its all hooked up and works fine.
Just wanting to know how to split the humbucker in the middle position (ie. send the red and white to ground when in the middle position)
Thats all! Thanks if you can help ;D

I definately dont want to use an on/on/on switch. Its too complicated for live use.
Is there any difference with putting the middle pickup before or after the volume pot???
I just thought it would be handy to put the middle pickup after the volume pot IF i could use it on its own when the master volume is turned down. Also to use the switch as a killswitch (when i've turned the volume down from the 3-way output).

Hi all, I'm a big fan of this site, have read heaps! Now i wish to change the wiring on my stratocaster. It is currently wired with normal 5 way switching, master vol/tone, and a neck on switch Basically i have little use for the 2/3/4 positions on it, and the extra 2 positions dont sound too interesting either. What i wish to do is replace the 5 way switch with a 3 way which selects neck/both/bridge. From there, the signal goes to the master vol/tone......now heres the tricky bit: Then it goes to a switch which puts the middle pickup in series with whatever else is selected. I think this wiring will work really well live, putting the middle pickup in series should be like having an onboard boost of sorts. I can work out most of the wiring, i just need help with the 'middle pickup in series' switch. I wish to use an on/on dpdt switch to do this, if possible. Thanks alot if you can help me out or provide opinions Edit: one extra question - If it implement this wiring scheme, and my master volume is turned all the way down, and my middle pickup switch is on....will the middle pickup be on by itself? Thanks!!!

What sorta job would you recommend to a young guitar nut such as meself?
The obvious answer being a guitar tech. But how many of those gigs are around?
Anyone got an interesting job? Doesnt have to be music related....
Cheers
