Yes,
Let me start by describing my 7 string since I can't publish pictures yet. I am using a 5 piece poly laminate Maple/Purple heart/Maple/Purple heart/Maple. The body sides are Mahogany. The neck is like steel. Mahogany is the best sounding wood but a pain to stain because it's like a sponge and it takes 5 coats just to fill to pores.
Anyway it is loaded with two Delano's. It is loaded with an sbc 7 and and sbc 7 quad coil on the bridge. Bartolini's are good enough but if you have money to burn these pickups have a better extended range.
1. Quad coil.
What I did was place the front coil where the jazz lead goes and the back coil is further back. I understand that the Fender jazz bass lead pickup changed position through the years so this gets both sounds. I wired it with an on/on/on toggle (Delano site has the schematic) so that I get front coil/both coils/ and back coil. You have to understand that they wire it like a P-Bass and a reverse Pbass so B,E,A,D is on one coil and G,C,F is on another coil. There is an option where you can put both the humbuckers in series and make a superbucker. I didn't go for this because it just made a louder version of what I already had. The Delano website will explain it better.
What I am getting is the back coils quack like a Jaco bass and the the front coils sound smooth like an alembic bass. A+B is a subtle combo of the two.
2. Standard SBC.
What I did with this was attach a series parallel switchpot so I only get two sounds. Parallel sounds pretty standard and series makes it Huge. I wanted no hum at all so I didn't mess with the single coils sounds but someday I might.
Rear coil is green + and yellow -
front coil is white + and brown -
Delano does not have a diagram for the switchpot circuit which is pretty strange but I was able to reason it out.
Now that you have a headache.
Bartolini also makes seven string pickups when you can get them. They are great, great, great but the Delano's are just a little bit better. Whether this justifies paying an extra $80 per pickup is up to you. Personally I'm glad I did.
Glad to have you back. I love seeing extended range bass builds.
