Re: Making Les Paul sounding like Telecaster
The problem with Teles is that they are vastly different than Les Pauls. Different bridges, different materials and different scale lengths. I have a Tele here at the house as well as a couple of modded LPs and the LPs don't sound like the Tele, but it is possible to get into the ballpark.
The first thing to do is verify what kind of guitar you have. Production LPs have a steel plate in the control cavity and this will limit your wiring options. The steel plate LPs will not accept dpdt pots without some fairly serious modification to the control cavity. If you have one of these guitars you will be limited to splitting the humbuckers because you need dpdt switches to series/parallel wire a humbucker. If you have a historic reissue, Epiphone or any other type of LP copy you can most likely use a sort shaft dpdt pot and then parallel wiring will be an option unless the cavity is very shallow.
Splitting will probably be your best way to go though so don't worry too much about it. I'd suggest splitting the pickups (both neck and bridge) for best results. What I have found it that while the neck or bridge split does sound somewhat more like a Tele in that the guitars tone becomes brighter, the combined neck and bridge split will get you that mid cancelled Tele tone that you hear on a lot of Rolling Stones clean guitar work.
As far as pickups are concerned I've found that 59s work well for this just because they are bright and spanky already and splitting them in pairs does sound fairly believable for the Tele thing but you can use any splittable humbuckers.
If you need long shaft pots the allparts part number is EP 4486. I just found a pair of those new in the packaging in my parts bin the other day while looking for a Strat 5 way switch.
My last suggestion would be to wire to opposite coils so both pickups split will be hum cancelling. I'd suggest wiring the bridge humbucker to split to the south coil (closest to bridge) as the tone will be a little tighter and brighter and split the neck humbucker to the north coil. That part is easily done by connecting the bridge red/white wires to hot instead of ground. Just run a jumper wire from the bridge pickup black wire connection at the volume pot to one of the spst switch terminals, the other terminal will be the SD bridge pickups red/white wires.
The neck pickup will split to ground as is normally done to split a humbucker.
). I have this pickups intaled in the neck and bridge position of a Guild S-100 (SG type of guitar) and I absolutely love the tone of this pickups.
