The Great Hammond B-3

Actually, the effect that Leslies acheive is vibrato.

Here is a good rule of thumb:
Vibrato: modulating the actual pitch of the note.
Tremelo: Modulating the volume of the note.

Interestingly, Fender got the two mixed up. On their guitars, the 'tremelo bar' (whammy) is actually a vibrato bar, since it's changing the pitch of the note.
On their amplifiers, you'll see that they include 'vibrato'. This is actually a tremelo system, since it changes the volume of the note.

but don't organs have a knob or button for vibrato and chorus?

Some Hammond organs have vibrato/chorus. I think the vibrato is simulated, however, with the use of a mysterious (to me, at least) device, the 'vibrato scanner'.
I have no idea how the chorus is generated, or what exactly it does to a note in any situation!
Some Hammonds also have reverb. Interesting fact: Hammond invented the 'spring reverb' system. Fender used the same design on their reverbed amplifiers, and had to license that design from Hammond... I always thought that Fender invented that system.
FloydWright: I did a little research... if you're still interested, the C3 is only the B3's guts put into a different case. Interestingly, this case is known as the 'church-type' case, so I guess your childhood dream will be realized!

Who knows? Maybe I'll get lucky someday! Believe me, I'll let you know if I ever do!

And thanks for the information on tremolo vs. vibrato.

we already covered that thanks to this really helpful, intelligent and all around great guy as you can see from above.

Seriously, though...could someone please define the following terms, because I'm sure I've HEARD the effects, but just can't put names to them.

Chorus...

Reverb... (I think I know this one...just checking to be sure)

And how would they tend to sound on a Hammond?

Like I have said before, I have no idea what chorus exactly does. (I just know it sounds good... )

Reverb is a naturally occuring effect. I'll give you an example...
Say you are in a big concert hall. You are standing on the stage, and the entire place is empty.
Suddenly, you clap your hands together once, loudly. You would probably hear an overhang of sound, as the sound bounced around the hall. This is reverb.
Let me say, however, that the terms reverb and echo are often mixed up. If you clapped your hands together, say, in the Grand Canyon, you would hear the sound bouncing around in distinct patterns, i.e. hearing the sound over and over again. This is echo. Reverb is unique because it is missing these distict repeats... I can't exactly describe what reverb sounds like, but I would say that your clap would sound more 'atmospheric'.

Reverb can also be reproduced (in analog) in two ways: by a spring reverb system, or a reverb 'plate'.
The spring system is really quite simple. A spring, usually about 10 or so inches long, is stretched inside a 'tank', which is simply a rectangular recepticle for the spring and other parts. When a sound is fed into the spring, the spring vibrates back and forth, creating the reverb effect. A small pickup picks up the spring's vibrations, and sends these out to an amplifier, and in turn the speaker.
The reverb plate is simple, too. A sheet of thin metal (like foil, made variously of steel or gold depending on price and quality) is stretched on a metal frame. When sound is fed into the plate, the waves make the metal sheet vibrate, which creates the reverb. This is also picked up by a small pickup and fed into an amplifier, before reaching the speaker and, eventually, your ears.
Hammond, other organ makers, and Fender all used the spring system. I've personally never seen a reverb plate inside an amp or musical instrument, but they were used primarily in recording studios.

Whew... that was pretty long-winded. I hope I didn't bore any of you.
Anyway, that's reverb.
As for their usage on Hammond organs, it should be easy to hear for the reverb, if you dug what I said.
As for the chorus, I cannot attest to hearing this effect ever come out of a Hammond organ. I am kinda interested, actually, to see what Hammond chorus sounds like.

(Anyway, here's a little something to cheer anybody up who got bored by my little speech:



Have fun!)

Actually, that was very nice of you to do. Reverb is about what I thought it was...hopefully, someone can explain chorus.

(Bashful voice) Thank you!



BTW, I was happy to let "l'il humper" out to play.
