Sven appears to know that although roses on your piano is good, "tulips on your organ" is even better!

Sven is great, but he's cheating a bit – he has a bassist.

Even though it's been years since I was in a surf band, seeing the words Leslie makes me instantly think "Farfisa" and I get a bolt of joy.

For his solo on Zeppelin's Good Times Bad Times, Jimmy Page played his telecaster through Leslie speakers. It's definitely a unique sound.

That gorgeous ping at the beginning of Pink Floyd's classic Echoes is a grand piano being played through a Leslie.

The extremely filthy bass guitar sound John Paul Jones got on Zeppelin's Heartbreaker was also achieved with a Leslie.

Everyone who loves the sound of a leslie should have to lift one into an Econoline van every night for a year. Extra credit: with a B3 organ.

Just a guess: were Plant's vocals leslied in (Hats Off To) Roy Harper?

The thing I love about the Leslie (aside from the sound, of course, which is awesome) is how fuckin' weird the thing looks. You look at this old concert footage from the 60s and 70s, there's all these hard-rockin' bands blowing up their drumkits and snarling about the war and saying Fuck You to the man, and all the while there's like a little Victorian hope chest squatting on the stage amid the brambles of black wires and dull metal speakers, amps and monitors, axes and aces. What the hell is that thing? It looks like it should have a doily and a tablelamp on it, like your grandma should have a dish of inedible hard candy sitting on it. It can't be a speaker, it has no front. Just those little slits along the top. That doesn't look like rock and roll. Which makes the Leslie the most rock and roll of all.

Coincidentally, just minutes ago I ordered a rotary electrical connector from Mercotac. I'm planning on making a rotating speaker, and when I mentioned that to the engineer there, he said that Don Leslie was his uncle. They sell these parts mainly for wind-powered generators now, and the company is a spin-off from his uncle's work.

I mentioned that in my experience the Leslie speaker always gets an enthusiastic positive reaction whenever it's mentioned.

We had an Electrohome organ when I was growing up, and it had a Leslie speaker inside it. Normally I could only hear it, but even then I could tell it was somehow mechanical in nature. I did once get a chance to see it, though, when my dad had the organ partly disassembled to fix something. It was such a weird-looking mechanism, like something your imagination invents during strange childhood dreams, before you know how anything really works.

Without the Leslie, your electronic organ sounds a lot like your alarm clock. Sorry if they are heavy.

Extra extra credit if you had to load/unload said B3 into a practice space that was on the third floor of a building with no elevator.

Is this something Tony Banks used before he completely squandered his amazing talent with post-Gabriel Genesis [spits]?

I love this sound -- thanks for this post to honor its origin.

Born To Be Wild, Steppenwolf. The bass is run through a Leslie, as well as the organ. Near the end, you can hear the speed selection change.

I'd have to believe Procol Harum did that too. Magnificent effect, no evidence.

They are called slip rings, and have been used for signage for many years. One of the largest manufacturers, IIRC, is Moog (formerly Litton) in Blacksburg, VA.

I lasted about a summer of loading/unloading both for a friend. The B3 sat in his mother's basement for years and he decided to take it on the road. Good times.

Electromechanical instruments are my favorite examples that human engineering is not evolutionary. "I know, we'll take a mechanical oscillator idea developed for radio, slow them down to audible frequencies, put a half-dozen in a piano case, and use additive synthesis to get a few octaves, and pipe the result through a spinning loudspeaker. Brilliant!"

To explain the doppler effect for my physics class in high school, I tried to build a leslie speaker. I found a website that sold replacement parts of the top horn and glued it to a portable record player.

I spent all night working on it and brought it to class the next day without trying it. I played two octaves (440 and 880) at three of the speeds (33, 45 and 78). It worked like a charm and even I was incredibly amazed at the sound. As far as I'm concerned, Don Leslie is a genius.

This is true. Leslies are how you create the awesome piano effect at the start of Pink Floyd's Echoes.

Why is a Mercotac rotating connector superior to a slip ring?

I don't know where this fits in the product line, it's not used in the classic designs. It has a liquid mercury bearing, as did old lighthouses, on a somewhat grander scale. The smaller, two-conductor, unit is relatively cheaper. I was told that is because that one was mass produced in Japan for musical purposes.

The use of a Leslie speaker was instrumental in producing a number of key effects in The Beatles' oeuvre. This is probably the most famous example. Their producer George Martin fed John Lennon's vocals through a Leslie to create the effect of him singing from a high mountaintop. (SLYT)
