you rule.

awsome

I certainly don't rule, but thanks for the compliments.

On to winding the pups. The copier had a number of solenoids. The resistances were in the 50 to 80 ohm range, and the wire gauge probably in the mid 30's, so obviously wouldn't match the input impedance of a guitar amp. I'd need active electronics to match impedances. More on that later.

Here is a solenoid from the copier.

I made a simple spool holding jig (the fret slotting jig, upside down ), and wound the pickups by hand. One took about 900 turns, and the other 600.

The bridge pickup.

The neck pickup.

 

[crazydoc]

Both pickups.

I later smoothed the top of the bridge pup with some epoxy, and painted the tops dark brown to match the guitar colors.

 

[crazydoc]

I had some piezo discs, so I mounted them under the bridge.

Just another tonal option. Very bright and gritty.

The electronics. I found some circuits on www, and used variations (available components) on the guitar. This one seemed it would be good to match the coils to amp - a common base configuration.

And this one for the piezo pickup.

The copier had multiple circuit boards. I scarfed parts off them (got everything but the FET which I took from my parts bins), and cut a board down, cut traces to make into sort of a prototype board, and soldered in the components and wiring for the three preamps.

Unfortunately I didn't clean off the copper very well, so the soldering is pretty gross. The battery clip is the clip in an old 9v battery.

Top of board.

 

[crazydoc]

I did have to fiddle with the circuits and tweak them a bit before I made the board.

 

[crazydoc]

The nut - available materials. Old bones and antlers.

 

[crazydoc]

I used this piece. Although it looks trabecular, it was solid inside.

 

[crazydoc]

On the neck.

 

[crazydoc]

For string ferrules I used the ball ends off of old strings.

 

[crazydoc]

Countersunk.
