Vibrato or Tremelo?

This is a question that has been asked several times, and it's time to address it!  This particular E-mail says it all...

"About that Vibrato, it's kind of a misnomer, since it's technically tremelo (raising/lowering of volume) though they say "Vibrato" (raising/lowering of pitch).  I don't know why instrument manufacturers do that. Fender still does that on their amps, saying "Vibrato" when they mean tremelo.  The only company I recall actually being right was Leslie (Electro Music), since the rotating horn/rotor raised and lowered the actual pitch. They even gave the slow/fast speeds names:
Slow - "Chorale"
 Fast - "Tremelo"  
I'm not sure if that's very interesting, though I've heard of people playing Wurly's through Leslies."

What's a "LESLIE", you say?  Click HERE to read more on that subject!
