In Praise of the Coil Tap

Message Bookmarked

After getting a coil tap installed on my PRS Santana SE, which has a Seymour Duncan Custom in the bridge and a Jazz in the neck, I wonder why these things are not standard issue more often on guitars. It really opens up a guitar for so many other sounds. I could also not believe how much an improvement in sound some good pots add to a guitar.

The coil tap has satisfied my interest in a strat, as I can now get something close now with this guitar. The tones in the middle position are now fantastic with the coil tapped and just the two humbuckers.

I'm thinking about getting a coil taps put on my Epiphone Les Paul, which has some Seymour Duncan Alnico Pro II pickups in a couple of weeks.

Did you add a switch or are you using a push/pull pot? How are you getting all 3 pickups at once? Blend pot?

Also, what exactly is the difference between coil tap and coil split? I'm interested in these different types of wiring options but with all of the parallel, series, etc. options it starts to become very confusing.

I suppose my wording was a bit off, it sounds good in the middle position with either both humbuckers or the coils tapped in single coil mode. It used to sound like mush in the mid position, which was dissapointing. With the new pots and the coil tap, the mid position now has two very good and somewhat different sounds.

The push pull is on the tone knob, which taps both humbuckers putting them into single coil mode. The way the Duncan pickups work is that they have four lines out and when you pull that switch up, it only uses the front coil (I think) of the pickup making it a single coil. It is the vanilla coil tap set up, but it is still pretty cool. You get to go from having three basic pickup sound setups on a guitar to six, which raises the possiblities. I did not have a guitar with a single coil pickups, so this helped out.

I think having some good quality pots have greatly improved the sound of the guitar. It sounds like someone took a blanket off of the speaker.

Depending on how the pickup is wired and set up, you can get into all sorts of esoteric things like choosing which individual coil will be used and changing the phase arrangement. I'm pretty much just starting to pick some of this stuff up.

"Split" and "tap" in this context mean the same thing everywhere I've ever read or heard about it.

Parallel pickup wiring is pretty uncommon though it can be really cool. All the Danelectros use it. I have a 6 string Dano Mod which is an SSH configuration (they made the humbucker out of two lipstick pickups!) and has a 6 position switch that gives each of the three pick ups as well as every combination of 2 (i.e. front+back, front+mid, mid+back). All of the combinations of 2 are roughly twice as loud as the single pickup settings because they are wired in parallel. (There's a coil tap on that humbucker too, incidentally.)

Dano adds another small switch that actually turns on all three pickups at once. There's an almost absurd change in volume going from one pickup to all three in parallel, but I love the fact that I can use it to overdrive an amp without a pedal.

What wiring options are you confused by/interested in?

The problem is that I have a "how to make an electric guitar" book that goes into tons of detail with all of the wiring options, different pots, tone controls, switches, etc. There are so many possibilities that it just becomes overwhelming and my desire to tinker is ruined.

For your information, coil tap is completely different to coil split.Coil split is when you turn a humbucker into a single coil, this is common. What is not so common is COIL TAP. This is where a pickup is wound so that it has a TAP or extra two wires coming from the coil. So you can (via a switch) have the full coil or part of the coil, hence, the tap. So what happens is that a pickup now has two options as to the output strength so if you have a single coil pickup which at full strength has a DC resistance of say 6.5K, you could switch so that the pickup would now have less DC resistance, say,4K or whatever. This is only possible if the pickup has been WOUND that way in the first place. This is totally different to coil split.
This option is not common on pickups and I can only assume that the makers are lazy pricks and just want to sell more pickups. If you did indeed have the TAP option, people would not keep buying and selling pickups as they do. I wind my own pickups and by adding a TAP to a single coil, you are infact adding another pickup to the guitar. So you can have one pickup that is hot and raunchy but with the flick of a switch, that same pickup can now be nice and clean. I know, this sounds like what you do with a humbucker but by Tapping a pickup, you can get Better Options. This all has to be planned out before the pickup is wound and also is a trial and error technique but once you find where the tap sounds best, you can't buy a pickup like that.
One last thing if I may, to the clown who sucks himself off. Get a life fool.

Ah, I was so much younger then, I'm older than that now.

I've got a few burn scars from wiring pickups.

Coolest weird thing I have is an old 1977 Ibanez bolt-on Les Paul copy with three of their "super 70s pickups". Guys at RS guitarworks set me up and I now have it wired with the middle pickup on a dip switch that will turn it on and off with a standard Les Paul switching. The pickups are pretty low output for humbuckers but you get these really cool kind of out of phase setup with the middle pickup and with it flipped on it is all three pickups. Totally bonkers guitar with a thin ass neck, but it's cool for recording. It definitely has some different sounds built in with current wiring.

Oh yeah the guitar had at one point in the 70s or 80s been rewired using the cabling out of an old lamp, that molded crimped looking stuff. There is a thin line between being desperate and being stupid.

Years ago on one of my early guitar builds, instead of soldering the components, I connected them together using a terminal block. In theory this meant that I could easily change the wiring whenever I wanted, but in practice the wires kept falling out and breaking off in use, making the guitar incredibly unreliable.
