I recently finished a 3 stringer with 2 pickups controlled by 2 volume pots,instead of a 3 way switch.Thanks to David L.for telling me about this idea (Stracciatella Mod). I used the coils from 2 Gitty Gold Foil pickups.Diodes are soldered between each pot and the jack. Instead of soldering my grounds to the back of the pots, I flattened a piece "tin" from a can and mounted the pots thru the metal and tied all the grounds together with a bolt. It made a nice clean connection.

Just realized the Neck and Bridge #'s are reversed on the 1st 2 titles in the video

Okay I understand what the diodes are for now, they separate the signal much like a toggle switch does.

Some of the hum comes from the amp setting in the video its at the "marshal stack" position, set at the "Black Panel" position its much quieter. The strings are grounded.

Here is the Stracciatella Mod video. The impression I got concerning the diodes, is that they isolate the pots. David L. knows about this sort of thing. David if you are watching whats the story with diodes? I'm much more comfortable with string then I am with diodes.

At the bottom of this page, Mr Stracciatella explains the diodes, it made my head hurt to read. http://www.strat-talk.com/threads/the-stracciatella-3-volume-w-vari...

It's a nice build and the string adds a nice homemade touch.

My J Bass works like this. 2 volumes and 1 tone for 2 pickups that are always on and you basically turn down the pickup you don't want.

You have some hum going on in the background. Could be a few things. Are the strings grounded? 1 of the pickups should be reverse wound/ reverse polarity of the other for "humbucking" while using 2 pickups. the pickup wires to the volume pots could be the problem since they are "coiled" and could be causing RF noise in the line.

What are the diodes for?

Interesting way to assemble with the string.
