Bear, a magnetic field in variance within a coil produces flow.  I don't know about running ti through a phono preamp as opposed to a guitar preamp... but I'd say it would produce some kind of sound.  Definitely worth an experiment.  But I would wonder two things:

1) How much can you magnetize an entire string and

2) How much of an opening would you need to leave in the coil to allow the string to freely vibrate?

I do believe it would make a very interesting experiment.  You could perhaps wrap the coil around a piece of paper straw to test it out.   Note:  I'm guessing it will take a lot of wraps to generate any effective current.  You'll need to experiment to see how many.  Please let us know how it works.

(I'd start with 10,000 wraps just as a beginning point).

I was watching a video about the different kinds of phonograph pickups and the "Moving Magnet Cartridge" made me wonder, if you magnetized the string itself and ran it through the center of a coil, and ran it through a phono pre-amp, would it work?  I thought I'd ask before spending the time to find out just in case someone else had already tried it, No sense reinventing the wheel.

Here's one I did with the front of the box as the back of the CBG.  One where you can open the back to change the 'string tru' strings. You need to make a solid block. http://handmademusicclubhouse.com/photo/albums/swamp-growler.

I read where it said to ask anything so here goes,I am making a box ubass. Now I am at the place where I need to make a place for the bottom end of the strings.I ask this over at the Nation and did not get so far. I see on Youtube where folks have converted giutars to ubass.The will have strings coming out of the top. How are they doing this without a hole in the back? I am using a two pc.box and wanted to mount the lid with glue so it don't rattle.

Thankyou Bobby

 hey all you madmen (or women), posted pic of an idea, small elec motor that turns wheel of picks, to keep plucking a tempo out, if done right maybe even a chord. i just got entire motor, power source ,on /off switch from a toy mouse kit my nephew had.  hey give it a try post outcomes...

im thinking about adding a minty amp to the inside of a guitar. just with a filp if button, its electric. plus no external cables. i guess for a living room setting type of cbg. i know its been done before, but seems pretty "mad lab like". ill post pics on here when done for reference and what have you

Teddyy could you please draw this no electron person 2 diagrams.
1. 2 piezo's going to volume pot to jack
2. 2 piezo's going straight to jack.
3 Thank you very much
Comment by bairfoot cajun on November 21, 2009 at 3:43pm
and fer my first project in the mad scientist lab i,m a gonna try to do an area 51 transducer where the piezo is mounted into the headstock. inside the paremiters of area 51. it will only be an addition to the modification of the instrument as it will have a tesla inside the body fer good amplification.
