One more variation added, to get the full HB, OoP with the Neck. The only way to get the Neck single is in one of the first 4 selections, with the S/P switch in series, and the blender turned all the way to Neck.
JohnH sent this to me via a PM. Thinking it might be poor form for him to post it in this thread. Not so, John. I think it either belongs here, or in it's own thread. I'll leave it in my post for now, and invite you to put it in the second post, possibly with a blender option, or start a similar thread.
John's version uses the second switch to bypass one coil of the HB in positions 2~4.
A nice development of designs. Blender is good and I suggest 250k linear with mid-track cut zone. Any higher value pot and the blending is only at the ends of the travel, but without the track cut, a 250k pot loads the pups too much.
Your config. is an alternative to using the 5-way switch to do overall pup combos eg N,NxB, N+B, Nx(-B_B, with the toggle/push pull to get the Hb coil cut.
With the right pups, an Hb/Sc system can get all the tones that I actually use. But theres one that I like that yours cant do, which is Bridge Hb in series with Neck OoP.....
EDIT 13/08/07 At Unk's invitation, here is my version, with Blender and pots added:
Unks use of a cap on the wiper of the blender offers some extra tones, particularly if it is rolled off in favour of the bridge, leaving some extra bass weight coming through from the neck. Could be added to my version too.
