I use a phaser . . . same thing?
...I wonder what sparked development of the Leslie rotating speaker...it seems kind of odd..."hey let's build a speaker and then put a rotating baffle in front of it...it just seems counter-intuitive to put make a speaker with a rotating obstruction in front of it.
I have no clue, but probably police/ambulance sirens inspired it. You know how sometimes you hear something and then think "that would sound cool on something else"...
Here's another link that might explain why they created such a beast in the first place.
Oh, and SRV's most famous Vibratone song was 'Cold Shot'. Say "Vibratone" and eight people will immediately say "Cold Shot" back at you.
Leslie manufactured the Vibratone for Fender. It differs from the big wood cabinets that we usually think of as a Leslie in that the Vibratone only has a single driver (10" or 12") and a styrofoam rotor. Big Leslies have two drivers: a 12" or 15" woofer facing down into a wood rotor, and a high-frequency driver firing through a double-sided rotating horn. The top and bottom rotors turn independently.
I believe the Leslie was invented to make electronic organs sound more like church organs. I'm a huge fan of them (for organ), but being an older rocker, my fav was probably Mark Stein of Vanilla Fudge. I was completely fascinated by their sound - couldn't get enough of them.
The inventor, Donald Leslie, died in September 2004.
