HUNTROLL presents . . . The Great Split / Tap debate . Please add your 2 cents to this cloudy, often function-wise misinterpreted topic ! Hate it, love it - How's it work, what's the deal ? I don't know, here's my take on it : I too agree about the misuse of terms - Split and Tap, when it comes to describing pickup functionality. I suppose if you consider where the two coils in a humbucker connect as its "TAP" connection accessing point, You then "TAP" the pickup by electrically grounding* that "TAP" point. *(by means of a piece of wire or a capacitor). I would call it "SINGLE COIL MODE", especially when its done with a wire and it can be measured with an ohmmeter.** 7 K ohm R pickup in parallel with 7 K ohm T pickup = measured 3.5 K ohms. then 3.5 K ohm (SCM R) in parallel with 3.5 K ohm (SCM T) = 1.7 K ohms, ( roughly ). **(as shown in my modified mini-HB HP picture). And if its done with a capacitor, you're "TAP" -ping certain frequencies. Now the "SPLIT" function is a little bit more complicated to grasp, (for me as least). Through real world deciphering this is what I've found : On a Gibson HP, when set to do "SPLIT" on the PC board, in each pickup, one of the humbuckers' coils is electrically REVERSED in POLARITY, (that's why it takes a DPDT switch to do it). That alone makes a humbucker sound funky individually but here's why I think its known as SPLIT mode . . . When you have both HUMBUCKERs ON and both are set to SPLIT mode, The two coils that are now set to be "out of phase" with their internal coil mate, are now actually IN PHASE with each other. Thus creating a VIRTUAL PICKUP that's been "SPLIT" out from the REAL pickups. Got it ? I guess you could call it "SPLIT PHASE MODE". Is that right ? If you know different, please enlighten me !
