Title: A pickup wiring question...
Post by: stratavox on June 18, 2015, 10:29:04 am
Decades ago, Bill Lawrence showed a way to split the coils of his "blade" humbuckers by soldering the "tap" wire to the unused lug of the tone pot for that pup. Roll it (the tone pot) full on, grounds the signal, splitting the coil. Back the pot down a hair, and we're back to a hb. My question is, in a guitar with two hb's, two v, and a SINGLE tone pot, can I attach BOTH the "tap" wires to the same tone pot, or will that cause an interaction? Hope this makes sense...tia.

I think you mean this:  http://forum.grailtone.com/viewtopic.php?f=10&t=28461 (http://forum.grailtone.com/viewtopic.php?f=10&t=28461)


This seems to defeat the use of the tone pot.  Also, I do think that 2 or more the PU's would interact, unless shorted to ground. 


As one poster on the grailtone site suggested, why not do the Jimmy Page mod?  Preserve the tone control and use SW's.  Maybe push-pull SW-Pot combo's.

On a single pot, they would interact.  You could, however, use a ganged dual pot.  But I'd use a DPDT push pull, and preserve the normal tone pot.
