It's possible to get some crazy sounds using an EBow on the guitar. I know that it works by creating an electromagnetic field to move the strings. Has anybody tried to build one? Are any schematics available?

The ebow doesn't just use an electromagnet, it also senses the pitch of the string using a small pickup, and amplifies the pitch using the electromagnet causing the sustain. If it didn't use a pickup, the pitch it would have to use an arbitrary frequency, which would cause the string's vibrations to cancel or switch to odd harmonics. – Anonymous Mar 5 '11 at 16:58

Take a look at this page. It provides some decent background technical information.

It sounds like a fairly interesting DIY project, considering as real ones go for over £70-80!

Hope this helps.

of course calling the contraption an e-bow (and especially trying to sell it) would cause you serious legal trouble. It's a trademarked name, and there might be patents involved as well. – Anonymous Mar 7 '11 at 7:00
