Location: Orange County, California | Electics *can* have a pre-amp. They're often called "active electronics" and its mostly for tone control, although some do add "gain". There are magnets in an electric guitar pickup with a coil of wire around them. when something magnetic (the string of the guitar) move in and out of the magnetic field created by the pickup, it (new word) "Induces" an electric current in the wire wrapped around the magnet. This is an AC signal, and it's got enough ooomph all by itself to "overdive" many amplifiers.
(side note) Guess what would happen to your strings if you applied an ac signal BACK INTO your pickups. OK, I'll tell you. They would MOVE back and forth with the signal. This is the principal behind a really cool device called a Sustainiac
Yes. They are a whole 'nother animal. |

And it's how the EBow works as well. |

All the knowledge here is mind blowing. I'm just trying to learn as much as I can so I can understand a bit more about my instrument and what makes it work.
I've got a few more questions to come but I think I'll wait a few days.....don't want to wear out my welcome :) |
