Anyone else every played with coil filters? I must say I have never had quite as much urge as I do right now to drill another hole in my already extremely cluttered control cavity. The story of the day - Coil Filters. Now we all like humbuckers I am sure, but they can get a touch muddy at times, especially the neck ones. A humbucker cancels out noise, and some frequencies along the way in order to do its job, some of us really like that bitey single coil tone too. In comes a coil filter. Fun111 can be shot on sight for planting this idea in my head. In a normal serial humbucker linkage, you have the south and north finish wires tied together. What happens if you insert a capacitor to this linkage and ground the 2nd leg of the cap (so attach both finish to 1 leg and other leg to ground). What is going to happen is you will bleed off the highs from a single coil, much like a tone knob. Let's take this a step farther, lets put a 'tone knob' in that linkage, wire the coil finishes to 1 side, and the wiper to a cap. You can adjust a low pass filter for a single coil, big deal you say, you are losing highs from that one coil right? Wrong. By bleeding off the highs from the one coil you are effectively BRIGHTENING your signal. The lost highs now no longer cancel the highs of the other coil, giving you all the humbucker fatness at the bottom, and a lot more bite/brightness at the top. I recently tried this on my neck bucker of my H-H guitar, temporarily commandeering the tone pot. For those who don't know my H-H guitar is a tonal chameleon, it has a master mode for both pickups of series/split/parallel, out of phase, and a 3 way switch. Normally that is enough to get by for a guy, but not this one. So I took my series/split/parallel wiring and the jumper for series mode (spans from 2-4 on a DPDT switch) was intercepted and sent to the tone pot for the neck pickup (I don't think you can do both pickups on a common pot without a switch to go between or one of those HCPs, I wager there would be some pickup cross talk). So I gave it a try with a 0.022 cap. Meh Then I decided to up the anti and put in a .047 cap, for a guy who thinks a .022 is too much for buckers on a tone knob this was a leap of faith. Damn it made the difference though. Now I could introduce so much bit to the neck, or sweetness on top that a neck humbucker usually has 'muted' clean. I tried it clean and driven to see the difference and driven it is a wonderful beast. Instead of dull, boring power chords they gained a whole bucket full of bite. This will ofcourse introduce a chance for noise but it is pretty freaking awesome. Thing is I need my tone pot too, so it looks like it is modding season again. With a push/pull pot I could rig this up to be useful for either pickup. (neck down, bridge up). Would need a brad point bit to drill first though. No sound clips available unfortunately, my interface is lent out to a friend. Anyone else fiddled with coil filtering?
