Petros Posted March 17, 2008 Report Share Posted March 17, 2008 (edited) Converting HH guitar to switchable HH/SSSS modes. I'll explain. Lace makes a pickup they call a "Dually," which looks like a humbucker but is actually two true single coils placed side by side. They're designed to be very low noise even as single coils. Using a set of these pickups you can create a guitar that switches from humbucker-humbucker (HH) mode to a true 3 (or even 4) single coil (SSSS) mode. The wonderful world of wiring and switching should be able to get you there, but I'm having a little trouble finding a diagram. The closest I found was an excellent design for creating a HSH configuration with three pickups (here: http://www.alloutput.com/Wiring/hsh_wiring.html ) Although it would work, I don't simply want to remove the single coil from that configuration because it would create dead spots on the switches. Next, I found the many wiring diagrams at GuitarElectronics ( http://guitarelectronics.zoovy.com/category/wiringresources/ ) , but none of the HH combinations (each with two 4-wire humbuckers) will provide me with how I want my guitar to function. I then found this interesting wiring scheme http://www.1728.com/guitar5.htm in which two humbuckers (each is the 4 wire type) gives you many series/ parallel combinations, but always keeping the guitar only in HH mode, and I'm looking to switch to a true single coil mode. *Essentially, I'm looking to be able to have any combination of two single coils connected in either parallel (for the traditional single coil strat sound) or in series (for the hotter Les Paul humbucker sound). I need a parallel/ series switching option, and I need one volume and at least one tone control. Okay, if you're still with me, the most simplistic idea I had at first was to create an on/off switch for each of the four pickups, something like the Brian May design in which the only "bad" thing about it is 1)you may have to flick multiple switches during performances and 2) you can't blend the individual pickups. In place of each switch you could use a Volume pot, but I'm not sure if there's something wrong with wiring four 250k pots as volume controls in the same circuit (something else I've not seen in my searching). But if you can do that it would be an advantage over the on/off switches because you can "blend" and still shut off the pickup by turning down the volume knob full. The "bad" thing about the four volume knobs is that it would be hell trying to get consistency dialing in a sound you like, and you'd need space on your pickguard for four knobs. Now where do you put at least one tone pot? Then, I thought of using a 3-way switch for each single-single (what Lace calls a "dually") combination. Each set could switch: 1. single coil north 2. single coil south 3. both single coils (essentially humbucker mode) With the two 3-way switches you would need either an on/off switch for each pickup set OR I think you can use another 3-way wired so that up is the neck pickup set, down is the bridge pickup set, and middle is both pickups. Again, I have no clue how to add yet a fourth switch to include parralel/ series options. Has anybody come across a wiring diagram for two humbuckers or four single coils that would approximate what I'm looking for? Ever see the four volume pot configuration? Some advice?
