Advice on Attempting Hentor Replica

It has to do with nodes, antinodes, amplitude and a few other things. Depending on where a pickup is placed, it will be excited by the string vibrations differently, so it'll sound different.
 
To supplement Cagey's reply -


If you imagine a jump rope, consider the travel of the rope in the center vs. near the handles.  The rope travels a lot further in the middle than at the ends, despite the frequency (the number of rotations per time period) being the same at all points along the rope.  The same is true of a guitar string.  The way the string disturbs the magnetic field of the pickup is different at various distances from the end of the string.  This is why the same note played on a Strat has a different timbre depending on which pickup you have selected. 


Now, IANAE (I Am Not An Engineer), but I know that this is complicated by the interaction of the pickups with each other.  If you have two pickups of roughly equal strength, but one is wound and polarized the reverse of the other, common mode rejection operates to eliminate not just 60 cycle hum, but also other stuff that both pickups are receiving identically, resulting in the "quack" of the in-between positions.  You'll need to get Cagey or Mayfly or line6man or one of our other resident engineers to give you more than that.


I found these neat things as I was verifying whether I was about to grossly misstate something:

Interesting.  I always find it puzzling how some folks will use a LP toggle with a 3 pickup guitar, and I never have explored "how" to wire up a toggle for this application, but it looks reasonably interesting.
 
Fender's been doing it with three pickups for over 60 years. (not accounting for the RW/RP dealio in the middle).

Can someone explain to me the rationale behind putting two identical pickups on a guitar and then switching between them?

It's a special toggle. It's like the one in some of the three pickup Black Beauties. They were wired B-B/M-N. I have one left over from doing a build like this for a buddy. If I remember correctly it was about a $30 switch.

Thanks, Bagman.  I have a degree in communications electronics and use to install and repair radio equipment. I understand basic reactive components like inductors and magnetic fields.  But, I still feel a bit like an idiot when it comes to pickups. I'm guitar stupid.  :icon_thumright: Obviously I'm going to stick with the dual FS-1 config.  Be reading up on these links over lunch tomorrow.  Thanks!
 
Talking volume and tone pots, would it be safe to assume these were both 250k pots?  StewMac recommends 250kOhm pots for single coil and 500kOhm pots for humbuckers.
 
For posterity's sake, a pick of the Hentor pickup wiring:

That pic reminds me.......the L500 needs to have the chrome housing as well. Alex says it sounds better  :party07:
