    I pulled the trigger on this home hot rodding project. This is the three pickup version I bought used http://www.sweetwater.com/store/detail/ENBBEBGH
    I am getting the Rio Grande texas pup set, should be here in 2 weeks. I will be replacing all the switches, pots, wiring. I am going to do a split pick up with the neck and bridge and be using the original center pick up though I want to add on/off and volume for it. still having problems with the wiring set up but have not gotten much feedback about this. If anyone could help check this thread {old-link-removed}. Can't buy the pots until I have a good plan so further research needed, but this should be fun.

    Surely you want to tap that center pickup as well. Otherwise you won't be able to get those in between tones like from a strat. Of course that also means another switch somewhere or fitting a 5 position switch instead of the standard 3 position. You could use a 6 way rotary in place of one of the tone pots and use a single tone pot for the pickups.

    Here's some wiring options for a coil tap.

    Yeah that would be great but I gotta draw a line in the sand somewhere, or do I? already looking at $400.00 in parts and the guitar cost me only $50.00 dollars more than that. The original pickups are 2 conductor can you easily split these? I thought they had to be 4 conductor and can't really justify the $ on another pickup. I have read that alot of people don't like rotary swiches, a 5 postion maybe (but will it fit in the toggle position?)

    I am not a fan of 2 conductor pickups. I had to re-wire a guitar for a friend, it having two conductor pickups, and it is a lot different if you are used to 4 conductor wiring methods. It's not impossible, it's just different.

    I think you should still be able to coil tap with 2 conductor pickups, but you might need to get fancy. You could try grounding out the base of the pots themselves (since in a 2 conductor setup they carry hot signal) rather than the wires. Or you could rig a separate pot completely that's connected to the bases of all volumes and have that pot grounded so as you roll it down all pickups effectively coil tap. i.e. Have the A wires (which come from the pot outputs) go straight to the switch and have the B wires go through the pot before going to the switch so you can control how much gets grounded. A simple on/off switch works too if you'd prefer it that way, but I think it would be cool to be able to control how much is grounded.

    ...Hey, it could work :lol:

    With re: to the wiring of the pickups, the replacement pups neck and bridge are 4 conductor, the Epi pup (center and not being changed) is two conductor. I know that terms coil tap and coil split are sometimes used interchangeably but it was my undestanding (or misunderstanding) that a coil tap is different than (coil) splitting a humbucker, and really refers to adding a wire to shorten the number of windings in the coil. I am definitely referring to splitting the dual coils of a humbucker to single coils. I guess I'll try one of the Les Paul forums for a wiring diagram. Thanks for the link Hueseph but it seems that most of those diagrams are for Strats and I can't make the leap to adjusting them to suit my purposes by my lonesome.

    You, JG, are indeed correct. According to the Seymour Duncan glossary, "tapping" a pick-up if you are pulling the signal off some shorter winding length of the coil(s). "Splitting" is switching a humbucker to a single-coil. Over the years, the term "coil tapping" has been used in place of "splitting", right or wrong.

    I got the pick ups today a set of Texas BBQ from Rio Grande, I bought them through a friend who owns a guitar store and he gave me a generous discount off the posted web one. Now thatI am officially a winter bum I'll get started on this little project after Bird Day and once I whittle down the honey-do list a little. Still have not found the wiring diagram I am looking for but I guess I'll experiment this might become the Franken-guitar but it isn't surgery so hopefully no one will die, LOL.
